How to clean an LCD TV screen at home - how to wash it without streaks

During the operation of the TV, dust and all kinds of other contaminants accumulate on the screen. Most users do not know how to properly care for such delicate equipment. Therefore, they use an ordinary damp cloth. This is a big mistake that can become a catalyst for premature failure of the device. To prevent damage, you need to know how to clean the LCD TV screen.

LCD screens are very difficult to maintain. Therefore, every user should know the rules of care. You need to choose the right cleaning agent, the material of the napkin or rag, and you should also adhere to certain safety rules.

Causes of pollution

The home environment is not ideal for operating technology of all types. Dust, particles of dead skin, and hair are inevitably in the air. Contaminants rise up and settle on the device, causing dark spots to appear on the LCD screen.

Other causes of pollution are:

fingerprints.
This reason is especially true in a home with small children;
splashes from liquids.
Traces on the screen can be left by both ordinary water and incorrectly applied cleaning products;
traces of insects.

Why does the LCD screen get dirty?

LCD monitors provide high-quality, rich and realistic images. But during operation they can become dirty for several reasons:

dust settling during irregular cleaning indoors or from open windows;
splashes from liquids during cleaning;
touching the surface.

Stains appear all the time, so users should know how to properly clean the smeared screen of a modern LCD TV.

What can't you do?

Proper care is the key to long-term performance of equipment. The more complex the device, the more delicate an approach it requires. To avoid damaging the LCD screen, do not perform the following cleaning steps.

Use liquid window cleaners

Users consider this choice logical, since the cleaners do not have abrasive components and are intended for smooth surfaces. But all household chemicals intended for cleaning mirrors and glass surfaces contain one of the aggressive components :

ethanol;
ammonia;
acetone or its substitute.

These substances dissolve the top coating of the screen, and their use negatively affects the condition of the equipment.

Clean switched on equipment

Before you start cleaning the screen or case, the TV must be disconnected from the power supply (unplug from the socket). This operation is necessary for two reasons:

Safety requirements oblige you to disconnect electrical appliances from the network when carrying out any manipulations with them. Following this rule will prevent the risk of electric shock:
When the screen matrix comes into contact with liquid cleaning agents while it is turned on, it may deteriorate due to the resulting electromagnetic waves. This will seriously degrade the image quality.

Use a fabric with lint

Lint from the fabric can get caught between the elements of the TV and stick to the surface of the screen, thereby increasing the degree of contamination.

Heavily fleecy synthetic fabric can magnetize the screen, which will lead to additional dust sticking to it.

When choosing a fabric, it is better to give preference to microfiber, fleece, or material designed for cleaning glasses lenses.

Wash with water

Direct spraying of liquid cleaning agents onto the screen is not permitted. This also applies to plain water. With this method of exposure, stains and stains will inevitably remain on the surface of the matrix from substances contained in the water. In addition, with abundant or targeted (from a nearby spray bottle) moistening, the liquid penetrates into the matrix and spoils its structure.

Scrape or scratch the surface

Any products that contain abrasives or come in powder form are not suitable for use on LCD screens. They scratch delicate surfaces, and it will be extremely difficult to remove traces of such damage.

Removing complex stains using a knife, blade or scissors is also prohibited. Any mechanical impact leaves scratches.

Sometimes they are not visible visually, but degrade image quality.

Turn on until completely dry

A TV and other equipment with a liquid crystal display cannot not only be wiped while in working condition, but also turned on until it is completely dry. Rapid switching on promotes the formation of streaks and affects the performance of the matrix.

Particular attention to LED surfaces

The screen matrix requires careful handling; when cleaning it, you should adhere to the following recommendations:

choose specialized products designed to care for LCD screens. Their release form can be any: active foam, spray or gel texture. Such household chemicals contain safe active ingredients and additional antistatic additives;
when purchasing a new, previously unused product, make sure that it does not contain alcohol-containing ingredients that damage the protective coating of the television panel;
Do not apply liquid or gel products directly to the screen. Such exposure will lead to the formation of rainbow stains and a blurry image. Such preparations are applied to a clean, lint-free cloth or microfiber, and only in this way is the screen treated;
do not press pointwise on the surface of the matrix and avoid excessive force when cleaning;
remove all jewelry from your hands when performing the procedure. Rings or bracelets may scratch the screen.

How Screen Type Affects Cleaning Method

Screen	How and what to wipe with
LED	A set that includes a spray and a microfiber cloth or cloth. The surface will accumulate less dust.
LCD	The cleaning composition is first applied to a napkin or lint-free rag. Next, you need to wait for the material to be well impregnated and wipe it.
Plasma	A soap-based solution is prepared. Microfiber or regular lint-free material is well saturated. Wring out so that there is no splashing from the rag or excess liquid. The rag should be damp, no more. Hand stains can be removed with wipes used to wipe glasses. Difficult places such as corner joints and edges where the screen connects to the body are cleaned with cotton swabs or a vacuum cleaner.
LCD	Wipes dry only. Before work, all objects (rings, chains, bracelets) are removed from hands to prevent accidental damage.

What substances are contraindicated?

Not just any product is suitable for safe and high-quality cleaning of TV screens.

The use of substances from the presented list is strictly prohibited.

Acetone

Acetone and white spirit are aggressive chemicals that damage the screen. Even a small concentration of these substances with short-term exposure is enough and the protective coating of the matrix will be irrevocably damaged. Not only these liquids in their pure form are prohibited, but also acetone-containing products.

Ammonia

The effect of ammonia or ammonia is similar to acetone. This highly active substance has a detrimental effect on the matrix, leaving behind rainbow stains. It will be impossible to get rid of them later.

Ammonia is often the active ingredient in glass care sprays, so this household chemical is also prohibited.

Ethyl chloride

This substance is strictly prohibited for use in the household, equipment is no exception. Ethyl chloride has a toxic odor, corrosive effects and a high fire hazard.

Gasoline or solvents

Gasoline and solvents created on its basis leave indelible rainbow stains on the LCD panel. The ban applies to both the pure substance and its use in diluted form.

Dyes

One of the most dubious means for cleaning electronics. In addition to the lack of cleaning properties, the dyes have an aggressive composition.

Under the influence of these substances, the top layer of the matrix is destroyed and stains remain.

Abrasive cleaners

Any products with abrasive particles or rough materials leave scratches on the delicate surface of the screen. As a result, watching TV is marred by distorted images.

Alcohol-containing products

On the surface of the TV screen there is an anti-reflective layer that does not tolerate aggressive chemicals. Under the influence of pure alcohol or products containing this component in high concentrations, the protective layer is completely or partially dissolved.

As a result, the quality of image transmission deteriorates, and the matrix becomes vulnerable to external influences, and dust sticks to it more quickly.

Washing powder and soda

Baking soda works well on grease stains and fingerprints, but should not be used on LCD screens. Small grains of soda do not completely dissolve in water and scratch and damage the surface. For the same reason, the use of washing powder or household chemicals in a similar form is not permitted.

Paper napkins and towels

Low quality paper products contain fine abrasives from unprocessed wood particles. They scratch the top layer and damage the screen.

Wet wipes for hands

Wet cosmetic and sanitary wipes have two negative impact factors:

Almost all napkins are impregnated with fatty components (cream, lotion). There are streaks and greasy spots on the screen;
Some of the napkins are impregnated with alcohol (for hand disinfection). This substance dissolves the upper protective layer of the matrix.

Did you clean the screen with wet wipes?

Not really

Removing scratches

The use of special pastes and creams intended for polishing and removing scratches from other materials (plastic, metal products) is strictly prohibited. To remove damage from LCD panels, only specialized substances for electronics can be used.

Prohibited methods and means

When cleaning LCD TV models, it is important to use only suitable techniques and materials. Absolutely forbidden:

treat the screen when the TV is on - the fragile matrix may be damaged;
turn on the device immediately after cleaning - crystals are sensitive to moisture;
use alcohol-containing products - the matrix elements turn white and fail;
wipe the monitor with damp wipes - they contain components that are not suitable for LCD surfaces;
use car cosmetics, products for windows, dishes, laundry - it is better to choose delicate products;
wipe the screen with newspaper - fibers remain on the surface or get inside, which leads to breakdowns;
spray the composition on the screen - the liquid may end up on important components that will break;
clean the monitor with soda - the abrasive will lead to cracks and chips of the matrix;
scraping off dirt - there is a risk of mechanical damage.

Important! Wet wipes leave stains that are very difficult to remove.

Fabric selection

The two main criteria when choosing a material for cleaning LCD screens are softness and lint-free. Cloths made from natural cotton, microfiber, fleece or lint-free flannel meet these criteria.

Special wet wipes for the care of LCD monitors

Wet wipes for LCD panels are the best way to quickly remove difficult stains. With their help, you can wipe dust from the screen and give the surface a slight antistatic effect.

The napkins cannot cope with complex stains; to remove them, you will need to apply friction, which is unacceptable.

In order to avoid streaks, it is recommended that you start cleaning the screen with a napkin not immediately after removing it from the package, but after waiting 20-30 seconds. The material dries a little in the air and does not leave wet spots on the surface. The best effect is achieved with the combined use of wet and dry wipes (not paper, but special ones).

Lint-free fabric

Such fabric can be soft cotton, fleece, flannel or material for cleaning glasses lenses. Most fabrics can be purchased by the cut at craft stores and cut into pieces of the desired size yourself.

Their properties are the same as specialized cleaning cloths, and the cost is several times lower.

A lint-free cloth can be used either dry or with an approved cleaning agent applied to it.

Microfiber cloths

Microfiber has the unique property of removing fingerprints or light grease stains without the use of additional chemicals. Also, with the help of microfiber, dried drops of water and dust can be easily removed. Microfiber, like other fabrics, can be used dry and together with a cleaning agent.

Due to its high hygroscopic properties, it is recommended to keep a cloth made of this material close to the TV to quickly remove accidentally spilled liquid.

How to wipe TV screens at home and how to properly get rid of stains and dirt

Now, armed with knowledge about the technical features of displays, let’s look at how to properly care for various TV screens without compromising their integrity, and what types of TV care products exist.

Old CRT TVs

The glass picture tube is not afraid of modern cleaning agents. The basic rule is to prevent liquid or spray from getting inside.

Therefore, before cleaning, be sure to not just turn off the device, but unplug the power cord from the socket. And only after the case and kinescope have dried can you turn it on.

To wipe the screen, use a damp cloth soaked in soapy water. Modern soft fibers with alcohol compounds, glass cleaning fluid, etc.

With success, the screen can be lightly scraped to remove stuck objects, such as children's chewing gum.

This is an undoubted advantage of older models.

How to clean and clean LCD TVs from dust, stains

A popular and affordable type of electronic equipment. However, improper care can overshadow the owner of a modern gadget.

A special feature of the front panel is its sensitivity to aggressive media: acetone, solvent, gasoline, car cosmetics, etc.

Also, a cloth moistened with damp plain water will not only not remove dust, but will contribute to the occurrence of washouts and streaks.

So how to wipe LCD TVs and how to get rid of streaks on the screen?

For this purpose, lint-free fabrics that do not contain abrasive threads and solid weave are suitable. Special sets and napkins.

The best means of cleaning the screen are:

lint-free soft fleece, flannel, flannel;
microfiber cloths;
cotton napkins.

These materials require a special cleaning agent. These can be sprays, gels and foams without an alcohol composition.

For example:

Patron F3-029 foam;
colorway 1032 spray with antistatic coating reduces the attractive properties of the panels.

Is it possible to wipe LCD TVs with wet wipes?

Yes, you can use special sets or separate disposable materials.

It is important that the packaging has a purpose - for caring for the screens of LCD monitors, televisions, and plasma panels.

Plasma panels

Due to the design features (the presence of LED cells), the models are endowed with significant dimensions. These are more powerful devices compared to LCDs, so the attractive properties of dust suspensions are increased.

In addition, fingerprints often remain when carried.

How to clean a plasma TV at home?

Manufacturers recommend using dry wipes and cloths for periodic screen care.

Microfiber cloths for wiping glass and mirror surfaces, according to experts, are the best solution. The material will allow you to remove dust and contaminated areas without the use of wet cleaning.

If you are unable to clean using this method, you can use a set of cleaning wipes. Contains dry and wet matter.

Plasma can also be cleaned with soapy water. To do this, fill a container with a spray bottle with warm and clean water and add 2-3 drops of liquid soap.

It is important that there is no excessive foam.

Reminder - the matrix consists of LED honeycombs. Strong pressure can cause mechanical destruction of the elements.

How to clean Oled TVs at home?

The requirements are identical to the conditions for caring for LCD TVs: soft lint-free fabrics, fibers, special wipes.

Cleaning products - any suitable for monitors and panels.

Special means

In terms of effectiveness and safety of exposure, specialized products for LCD panels are in first place. They not only carefully remove most household contaminants, but also leave a prolonged antistatic effect. The form of release of such drugs can be varied: foam, spray, gel.

When purchasing, it is important to pay attention to the absence of alcohol in the composition.

Gel

Gel-like products are used undiluted and only when applied to a rag. Applying the gel directly to the surface of the screen is allowed. Most often, the gel does not require rinsing with water, but detailed instructions are always indicated on the packaging.

Foam

A foam cleaner is used to remove grease stains and other stubborn stains. The method of application is indicated by the manufacturer on the packaging: directly on the monitor or on a rag.

Specialized foam cleans the LCD panel without streaks and wipes off its surface without using water.

Aerosol

The spray from the can can be applied to both the screen and a rag. The manufacturer always indicates exact recommendations for use on the packaging. The use of an aerosol is advisable for cleaning large screen TVs. When applying the product, you should not place the sprayer closer than 10-15 cm from the LCD panel due to the risk of damaging it.

Cotton swab for dirt on joints

Even microfiber will not penetrate into hard-to-reach places to remove dirt from them. For these purposes, it is recommended to use cotton swabs. The soft base will not damage the surface and will effectively clean it. To enhance the effect, a cotton swab can be moistened with any suitable cleaning agent.

Why does the LCD screen get dirty?

LCD monitors provide high-quality, rich and realistic images. But during operation they can become dirty for several reasons:

dust settling during irregular cleaning indoors or from open windows;
splashes from liquids during cleaning;
touching the surface.

Stains appear all the time, so users should know how to properly clean the smeared screen of a modern LCD TV.

Traditional methods

For TVs, you can use not only industrial means, but also improvised means.

Before use, you should read the instructions for household appliances and check for any contraindications.

Vinegar

In order not to damage the surface of the matrix, it is necessary to use a vinegar solution with a concentration of no more than 3%.

Algorithm of actions:

In a glass or ceramic bowl, dilute 9% table white vinegar and cold clean water in equal proportions.
Wet a lint-free cloth well with this mixture and wring it out thoroughly.
Turn off the device and treat the TV screen with circular movements without using force.
If necessary, repeat the procedure by wetting the cloth again.
Wipe the surface with a dry, soft, lint-free cloth.
Leave the screen until completely dry. Turn on the TV.

By the way! You can use vinegar to clean the handles of a gas stove, see here.

Soap solution

If there are contaminants on the surface of the LCD panel other than dust, you should use a soap solution to remove them. To do this you will need:

Grate toilet or baby soap (without cream additives) on a fine grater and dissolve in warm water. For 1 liter of liquid you will need ¼ of a bar. Laundry soap is not suitable for cleaning electronics as it contains a large amount of alkali.
Soak a soft, lint-free cloth in the soapy water and wring it out well. It is important to check that there are no undissolved soap particles on the rags.
Wipe the screen in a circular motion without applying force or excessive friction. If you have jewelry on your hands, you should remove them or wear gloves to avoid accidental scratches.
Soak a microfiber or lint-free cloth in clean water, wring it out and wipe the surface to remove any remaining soap solution. Repeat the operation.
Wipe the screen dry. Squeeze for 20-30 minutes to evaporate the liquid from hard-to-reach places and only then turn on the TV. For drying, it is prohibited to use heating devices, such as a hair dryer.

Isopropyl alcohol

This substance works well to remove dried dirt and fingerprints on a smooth surface.

To work, you will need 70% isopropyl alcohol; it is usually used to disinfect skin in the presence of wounds.

Mode of application:

Mix equal proportions of isopropyl alcohol and clean cold water in a container. It is impossible to violate this proportion and increase the concentration of alcohol, as this will lead to the destruction of the protective layer of the screen. If you don’t have a measuring cup, it’s better to make a less concentrated solution “by eye.”
Soak a lint-free cloth in the solution and wring it out well.
Wipe the surface of the device without applying additional effort.
Repeat the procedure, walking over the surface with a clean cloth soaked in the solution.
Wipe the screen dry with microfiber or cotton cloth.

Professional care products

It is most effective to wipe the TV screen with special compounds. All cleaners are safe and do not harm the screen if you follow the instructions for use. The instructions are on the packaging or on the container with the spray or gel. It is not advisable to deviate from the instructions, otherwise large stains and other problems may occur.

Features of caring for different types of screens

Flat screen TVs have different picture reproduction technologies. Depending on this, the rules for caring for them change:

LED panels. They can be cleaned using a microfiber or lint-free cloth, dry or with a product for LED screens applied to them. It is important that the drug does not contain alcohol-containing components;
liquid crystal screens. It is strictly forbidden to apply any cleaning agents directly to the surface of such panels. This will inevitably lead to the formation of streaks and cloudiness. All compounds are applied to a cloth, which is then used to wipe the screen. Joints and hard-to-reach elements are cleaned with a cotton swab.
plasma panels. Such screens can be cleaned painlessly with a soap solution and a lint-free cloth. For difficult stains, it is recommended to use microfiber. Handprints can be easily removed from plasma using a cleaning cloth;
LCD screens. The most delicate and difficult to maintain types of screens. They have a soft and thin matrix that is easy to damage. For cleaning, use only a dry soft cloth, without using any products. It is mandatory to disconnect the TV from the network before starting cleaning. It is important to remove all rings and bracelets from your hands and prevent the LCD panel from coming into contact with water or chemicals with active volatile vapors (gasoline, acetone).

How to remove stains?

The most common causes of smudges on the screen are touches from hands and fingers.

You can get rid of them safely and effectively in the following ways:

dry wipes: microfiber or for the care of glasses;
foam designed to clean a specific type of screen;
a mixture of water and 9% vinegar in equal proportions, with which a soft, lint-free cloth is soaked.

How to keep the surface clean longer?

To ensure that dust and other contaminants accumulate on the TV screen less frequently, and to clean it less frequently, you must adhere to the following recommendations:

remove pots with indoor plants from the appliance. They must be at least 1 meter away. They not only allow dust from the soil to settle into the flower pots, but also droplets of water when watering;
Make it a rule not to touch the screen with your hands . This habit should be instilled in all household members;
Place the device out of the reach of children's hands. It is the little viewers who tend to poke their fingers (sometimes stained with paint or candy) at the screen;
Regularly disinfect the house and eliminate the appearance of insects. Flies or gnats from houseplants can leave hard-to-remove black dots on the screen;
Use products with a pronounced antistatic effect to treat the surface of the screen. This way, less dust will settle on the TV, and it will be easier to remove.

Features of television screens

According to the type of displays, the following types are distinguished:

CRT - cathode ray tube;
LCD - liquid crystal;
plasma;
oled

Let's consider the features of each type in relation to proper cleaning and maintenance at home.

CRT - cathode ray tube

Model from the times of the USSR. The TV was called a “box”. Indeed, the loose wooden frame of an old non-working appliance could become a useful storage container.

Most of the device was occupied by a picture tube (CRT) - the prototype of modern screens and monitors. This is a solid glass flask with technical bells and whistles.

There was no question about the appearance of cracks and dents, since such flaws inevitably led to failure of the equipment.

Modern television receivers, instead of a picture tube, are equipped with a matrix with different technical designs. This is important to know, especially when planning a thorough wipe down with pressure on the screen. For example, to remove splashes, stains or traces of children's hands.

LCD - liquid crystal

A color monitor made of two panels, with a special liquid pumped between them. On the inside there is a light source that affects the characteristics of the liquid, changing the position of the crystals.

The applied filters, like in a mosaic, create areas with a certain contrast and illumination. This creates a visible, clear color image.

The difference between LCD and LED models is the light source. The first option uses fluorescent lamps, the other uses LEDs.

In general, this does not affect the screen wipe.

Plasma displays

The screen consists of cells filled with gas. The color of the element changes under the influence of electric current. These are large format models that accumulate a lot of dust.

OLED

The color panel is made of LED pixel elements that emit light.

These are expensive TVs and therefore proper care is important.

How to clean the case?

Regular care and cleaning is required not only for the TV screen, but also for its body. This procedure is complicated by the presence of a large number of depressions on its surface.

Remove dust

It is necessary to get rid of dust on the back of the TV at least once every 3-4 weeks, the optimal frequency is once a week. The best choice for this procedure is a dry or soft cloth slightly moistened with water.

More complex stains can be removed using any product (industrial or home) designed for the screen.

Before starting cleaning, the device must be disconnected from the power supply.

If dust gets into the TV connectors, then when using a cotton swab there is a risk of pushing it deeper and breaking the contact when connecting. In this case, it must be removed using a vacuum cleaner or blown out with air from a small rubber bulb.

Remove grease stains

To remove grease or other complex contaminants from the body, it is allowed to use:

wipes for electronics. They are impregnated with a safe solution that does not leave streaks and does not spoil the plastic. Most often, the use of these wipes for screens is not allowed;
special cleaning products for household appliances and electronics. On the label of such drugs there will be a note stating that they are safe for use on a TV (not on a screen).

How to properly take care of TV

You can clean your TV monitor:

Use a vacuum cleaner at minimum power, away from the screen. It is prohibited to bring the device very close.
Use a rubber blower to suck up the dust. At the same time, you should also not come into contact with the monitor.
A special broom with soft bristles. They can be purchased at household chemical or home improvement stores.
Clean the surface with a lint-free cloth with minimal effort. That is, it is unacceptable to press the cloth too hard. Otherwise, due to mechanical damage, dark or white spots will appear when watching films.

The purpose of cleaning is to remove dust from the surface so that it does not accumulate and form black spots. Under the influence of electromagnetic waves, microparticles of dirt can be “absorbed” into the matrix and harm it. It is recommended to wipe the surface 2-3 times a week.

How to remove scratches?

Scratches on the screen found in the first two weeks after purchasing the TV are most likely due to defects or are a consequence of improper transportation of the device. This TV should be returned to the seller.

If abrasion or scratch appears during use, it can only be removed with specialized means.

Independent attempts at “polishing” will lead to irreparable consequences. Electronics stores sell ready-made sets of wipes and scratch removers.

They are the ones who should be given preference. Among the safest and most accessible means, it is worth noting the following.

Petrolatum

This product is often found in home medicine cabinets and can deal with a shallow scratch on the screen. To do this, apply Vaseline the size of a match head to a cotton ball or disk and polish the damaged area with light movements without pressure. There is no need to remove Vaseline from the surface, just wipe with a dry cloth.

Anti-scratch varnish

This is an industrial product that is sold in electronics stores. Detailed instructions are always included on the packaging of such varnish. But the use of the product from most manufacturers is identical:

Turn off the device. Remove dust and dirt from the damaged area.
Apply the varnish to the scratch with a brush, being careful not to extend beyond its edges.
Leave the TV turned off until completely dry. This period can be from 5 to 10 minutes.

What means to wipe

You can clean liquid crystal displays with various products that are produced specifically for this purpose and are sold in appropriate stores. Among store-bought products, you can use the following options to remove dust:

wet wipes soaked in a special solution. For example: Top House or Cactus CS-S3002;
products made of lint-free fabric, which are attached to a bottle with a special product.

Important: to remove stains, you must use microfiber and spray according to the instructions and do not spray the product onto the screen; it is initially applied to a napkin.

In addition, to clean the LCD screen, you can use other TV screen cleaning materials, for example:

vinegar;
isopropyl alcohol;
soap solution;

Rules of care

The main principle of cleanliness of household appliances and electronics is regular cleaning.

Removing small dirt and dust is much easier than dealing with complex, dried stains.

The sequence and main rules for cleaning the TV are as follows:

Turn off the device using the button on the dashboard or remote control. Do not pull out the plug from the socket while the TV is running.
Disconnect the device from the power supply, completely de-energizing it.
Apply the selected product to a soft cloth or lint-free wipe. Soak the material well and, if necessary, squeeze it out. The fabric should be evenly saturated with the solution, but so that nothing flows or drips.
Check the surface of the matrix for the absence of abrasive contaminants on it. For example, soil or sand from a flower pot can get here. When cleaned, these grains will leave scratches.
Wipe the screen with light circular movements. Do not press, rub, or scrape dried stains.
Clean hard-to-reach places with cotton swabs.
Wipe dry with a clean cloth and leave the TV on for 20 minutes to dry completely.
Treat with anti-scratch or antistatic agent.

Periodicity

Standard cleaning periods:

removing dust using a dry microfiber cloth – once every 2-3 days;
getting rid of stains, fingerprints and other serious contaminants using industrial or household cleaning products - no more than once a week. The optimal frequency is once a month;
treating LCD screens with antistatic agents - once every two weeks, after cleaning;
getting rid of scratches - as needed, after thorough cleaning.

A clean TV screen is the key to high-quality images and comfortable viewing. To care for this equipment, the use of conventional methods is not allowed; the matrix of the device requires a delicate and careful attitude.

General rules for cleaning LCD TVs

By pressing the button on the remote control or on the equipment body, turn off the TV. Disconnect from the electrical network by removing the power cable.
Soak a lint-free cloth with cleaning solution.
Use slow rotational movements without applying strong pressure to wipe the screen.
If a napkin or other cloth has been used for cleaning several times, shake it well before wiping again. Inspect for small particles like sand. Old dirt or any abrasive particles can easily damage the screen.
Try to make contact with the screen only with the central part of the cloth.
You can clean the surface every day only with dry tools - a clean, lint-free rag or a brush with soft bristles.
Liquids, gels, foams can be cleaned maximum once a week.

It is not advisable to prepare the products yourself using improvised means. Unsuitable raw materials can cause the TV to break down. Even a barely noticeable defect can grow in size over time and interfere with normal TV viewing. Ultimately, you will have to change the matrix to a new one. Repair costs can reach more than half the price of the TV.

How to remove stains from LCD screen

How to clean your monitor:

turn off the device and remove the plug from the socket, wait until the device has completely cooled down;
remove bracelets and rings to avoid accidentally damaging the display;
Apply the spray only to a rag to prevent moisture from getting under the body of the equipment;
wipe the monitor, moving from one end of the screen to the other, to avoid streaks;
remove dirt in the corners with a toothpick, but be careful - do not rub too hard.

To clean dry stains, slightly dampen a rag and wipe the problem area, then wipe it dry. If there are sticky stains on the surface (from stickers, tape, chewing gum, glue), apply a drop of vegetable oil to a rag and carefully treat the problem area. When the adhesive has softened, remove any remaining dirt with LCD display cleaner.

If dust has penetrated into hard-to-reach areas, do not use a cotton swab to clean. This can push dirt inside, which will lead to poor contact. Try getting rid of dirt with a vacuum cleaner or blowing out the dust with the cold air of a hairdryer. But be careful: keep the device at least 10 cm away from the TV to avoid hitting it.

Prohibited methods and means

When cleaning LCD TV models, it is important to use only suitable techniques and materials. Absolutely forbidden:

treat the screen when the TV is on - the fragile matrix may be damaged;
turn on the device immediately after cleaning - crystals are sensitive to moisture;
use alcohol-containing products - the matrix elements turn white and fail;
wipe the monitor with damp wipes - they contain components that are not suitable for LCD surfaces;
use car cosmetics, products for windows, dishes, laundry - it is better to choose delicate products;
wipe the screen with newspaper - fibers remain on the surface or get inside, which leads to breakdowns;
spray the composition on the screen - the liquid may end up on important components that will break;
clean the monitor with soda - the abrasive will lead to cracks and chips of the matrix;
scraping off dirt - there is a risk of mechanical damage.

Important! Wet wipes leave stains that are very difficult to remove.

In a 1:1 ratio, dilute 3% table vinegar with water. We wet a soft cloth in the solution, then wipe the surface of the monitor. At the end, remove the remaining vinegar solution using a damp, then dry cloth.

Dilute 1–2 grams of soap in water. Using the resulting solution, wipe the contaminated area. Use a wet cloth to wash off the soap solution. This method helps remove grease stains.

Using isopropyl alcohol, remove greasy marks or dried dirt from the contaminated area. We dilute the substance with water in a 1:1 ratio. Use a lint-free cloth to remove dirt; remove any remaining solution with a damp cloth. Finally, wipe the screen dry.

What not to do when cleaning

To avoid damaging your LCD TV:

Do not wipe the device when it is turned on. The LCD matrix is very fragile and can be damaged by any power surge. For the same reason, you should not turn on the TV immediately after washing.
Do not use lint cloth or hard sponges - they will leave marks and streaks on the surface.
Do not use any abrasives or sharp objects for cleaning - scissors, blades, kitchen knives.
During operation, do not press on the surface of the LCD panel to avoid breaking the display.

What products should not be used:

Window cleaners. They often contain ammonia, an aggressive component that can damage the protective coating of the display.
Alcohol-containing liquids and hygienic wet wipes. They leave stains, and the components contained in the composition spoil the matrix.
Paper towels and newspapers. They scratch the display and form microcracks, which can lead to failure.
Acetone, gasoline, white spirit and other solvents. Even in small concentrations, these aggressive substances damage the protective coating of the screen.
