Periodically wash your jug ​​with acids or using other products suggested in this article, and it will always shine like crystal!

It is rare that someone has not encountered the need to wash the inside of a jug, vase or decanter. This is a very painstaking task, especially if the dishes are convex and have a narrow neck. The hand can’t get through, the brush only reaches the bottom, and the side walls remain dirty. There are proven ways to easily clean the inside of a carafe.

How to wash properly?

When using a dishwasher, you should set the temperature to the lowest possible temperature, as well as a special mode designed for glassware. However, constant use of the technique will cause the decanter to lose its shine.

To minimize the risk of glass damage, as well as to completely clean the vessel, you must adhere to the following rules:

• Warm water should be used for washing. A sharp change from high to low temperature, which provokes a gradual darkening of the glass, is especially dangerous for crystal.
• All rings and bracelets are removed so as not to scratch the walls.
• It is best to wash the decanter not in the sink, but in a plastic basin. As an alternative, it is recommended to place a soft rubber mat. However, the water should be changed constantly to prevent staining of the glass.
• You need to start washing the decanter from the outside, and then move on to the inner walls.
• It is best to use a soft bristle brush or sponge.
• A damp glass decanter or vase should be wiped with a soft cloth. If the neck of the vessel allows, it is recommended to place paper towels inside for 8-10 hours. During this time, all the resulting moisture will be absorbed. Do not leave the container to dry on the rack.

What kind of filter do you have at home?

In apartments and private houses, three types of filters are most often used:

• reverse osmosis systems;
• flow-through;
• jugs.

Reverse osmosis

The first type includes Geyser filters. They are good if you have to purify significant volumes of water - for example, for a large family. Install such a system in a carafe, in the kitchen or bathroom.

Important! It itself is quite large, however, it does not spoil the interior at all. It is almost invisible from the outside; all large parts are put away under the sink. This is the only type of cleaning in which scale does not form on the walls of the kettle.

Its main advantage is maximum cleaning. There are, of course, disadvantages:

• high price;
• professional installation required;
• installation takes time;
• such a filter does not protect household appliances from scale;
• There is a metallic taste in the water.

Flow filters

Such a device is cheaper than a reverse osmosis system. There is no need to boil the water either. The flow filter is smaller and easy to transport. They come in different sizes, and some also take a long time to install.

The most popular flow device is Aquaphor. If we talk about the disadvantages, the main one is that the body is made of transparent plastic, which quickly becomes cloudy. However, it is quite easy to find a unit of this class on sale, the installation of which will not take much time.

Jug filters

Strictly speaking, these are also flow-through ones, just because of the shape of the body they began to be classified as a separate class. These are the most popular water purification units. The device itself looks quite simple, it has two main parts:

The popularity of such devices is due to their undoubted advantages:

• do not require installation;
• You can start filtering water immediately after purchase;
• if the cartridge gets dirty, you can simply replace it;
• This filter costs much less than others;
• Design solutions are very diverse, so you can choose a jug to suit the interior of any kitchen.

Detergents

Food vinegar

To completely clean the walls of a glass product, it is recommended to use the following methods:

• White wine vinegar. The decanter is washed with water at room temperature, filled and left for 15-20 minutes. The liquid is then removed. Table salt is added in such a volume that the bottom of the container is covered by 2-2.5 cm. Vinegar is poured, and there should be 2 times more of it. The container is shaken for 1-2 minutes and then rinsed.
• Sand cleaning. The vessel is filled 1/3 with warm water, then 1 tbsp is added. l. table vinegar. The decanter is left for 2-3 hours. 30 g of purified sand is poured inside. The container must be shaken until the inner walls are completely cleaned, and then rinsed.
• Washing a jug with a filter for water purification. Mix kitchen salt and vinegar separately to form a mushy substance. The removable filter is removed, and the contaminated areas are covered with the mixture. If the vase has a narrow neck, then use a toothbrush to apply the paste. The container is washed with water at 40–45 °C after 20–25 minutes.

1. Soda diluted to a mushy state is poured into the container.
2. Add paper until the mixture covers ¼ of the container.
3. The decanter is left for 2-3 hours and then shaken.

Egg shell

The glass container is washed with plain water. Then a thick layer of eggshells is poured inside. The approximate height is 1.5-2 cm. Then water at room temperature is added. To add shine to the glass, you should also squeeze out 3-5 drops of lemon. The top of the vessel must be closed. It is recommended to shake the decanter until the dirt completely disappears, and then rinse it. Alternatively, the eggshells can be replaced with white rice.

Lemon acid

To remove plaque and also give the carafe a shine, it is recommended to use a food additive. It is necessary to fill the vessel with warm water in which 1 sachet of citric acid was diluted. The container is left for half an hour. If dirt still remains, the procedure is repeated. In case of limescale deposits, which form when the vessel is used for a long time without proper cleaning, it is recommended to combine citric acid with soda in equal proportions and fill with water. The mixture is poured out after 20-30 minutes.

To remove dirt stuck in the corners of the vessel, you can pour special decanter cleaning balls inside. They should be filled with warm moisture and then shaken vigorously.

Ice cubes

To quickly remove stains, fill the container with water at room temperature so that it fills 1/3 of the volume. Then ice cubes are thrown inside. The decanter should be rotated smoothly clockwise until the dirt streaks completely disappear. To enhance the effect, liquid detergents are added to the container. It is important to rinse the vessel at the end of cleaning.

Cleaning dishes with a narrow neck

No feast is complete without drinks. And if they are served in a crystal decanter, then the table looks elegant. And any housewife is upset when the decanter seems unwashed or cloudy; its beauty is dulled by the fact that it is not transparent.

To prevent this from happening, you need to know how to clean a glass carafe from plaque.

Before you start cleaning, you need to prepare everything you need. For washing you will need:

• warm water;
• soft cloth for wiping;
• cleaning products (each method uses different products).

Grandma's old way

When there were no detergents on sale, housewives cleaned dishes using soda and newspaper.
To do this, you need to tear the newspaper into small pieces, pour it into a carafe and add a thick soda solution there. All contents must be shaken well and left for a while. Then shake again for a few minutes, then pour out and rinse well with clean cold water to avoid streaks.

Vinegar can help

Vinegar is known to dissolve limescale. Housewives use this feature to wash dishes that contain liquid for a long time.

You need to take half a glass of table vinegar and the same amount of water. Pour the solution into a decanter (vase, jug) and, covering the neck with your hand, shake it for several minutes.

If the plaque is old, the solution will have to be left for an hour or two. Then pour everything out and rinse well with clean water. You can replace vinegar with citric acid.

Rice plus water

Some housewives clean decanters or damasks with rice. To do this, pour 2 handfuls of rice into a carafe and fill it with cold water and citric acid. Let it sit for a while and then shake the decanter, covering the neck with your hand. All contaminants are cleaned very well. After this, everything must be poured out and the carafe rinsed with clean water. If you don't have rice on hand, you can use buckwheat or pearl barley.

Jugs "Barrier", "Aquaphor"

Filtration devices are found in almost every kitchen today. There is always water in the upper part until it settles. If rusty water or water with a high content of heavy metals gets into the Barrier or Aquaphor jug, then you should take care of cleaning them regularly.

Washing even once a week will extend the life of your kitchen assistant. The filter reservoir is plastic. To clean it, you need to leave the soap solution for 1 hour or more, and then remove any remaining plaque with a sponge or soft cloth.

Valuable user experience

Judging by user reviews, there are many non-standard ways to solve the problem. Here are just a few of them.

I recently bought a ten-liter bottle with a narrow neck from a neighbor. It stood in his basement for a long time and turned out to be very dirty. But I took it anyway. I need such dishes because I grow grapes and make homemade wine.

To begin with, I washed the outside of the bottle well. It turned out to be easy. Using a sponge with dish detergent, I scrubbed off all the dirt and then rinsed well. But I was a little upset, because the inside of the bottle was even dirtier, and the neck was narrow; I don’t have such a brush. Even if there was, I still wouldn’t be able to reach the side walls.

I racked my brain for a long time about how to wash it. And this is what I came up with. I threw a steel wool for cleaning pots inside the bottle, and began moving a magnet wrapped in a cloth around the outside. First, I wet the inside of the bottle and poured detergent into it. After cleaning, I drained the soap solution, pulled out the washcloth, again using a magnet, and rinsed the bottle several times. As a result, my bottle sparkled like new.

I have two 20 liter bottles. I clean them with coarse sand and dish soap. First, I pour hot water into the bottles to soak the dirt, then I drain the water, add sand and add any dishwashing detergent. I shake and spin the bottle until the dirt comes away from the walls. Everything washes well. Try it yourself.

We often collect water in plastic ten-liter canisters. And it happens that dirt particles contained in the water settle at the bottom, even if it is perfectly clean. In order to wash, I use environmentally friendly ingredients:

I pour 10 tablespoons of soda and salt into the canister, pour in water to make a liquid slurry, and close the canister with a lid. Then I start shaking it all, making movements so that the solution moves in different directions. I shake it for probably 10 minutes. After that, I pour everything out and rinse the canister with clean water. Everything is perfectly clean.

I would like to give advice: do not use detergents, as they are absorbed into the plastic and can be difficult to remove, but soda and salt are food products and will not cause any harm.

How to clean the inside of a decanter? Dirty dishes are the main problem when cleaning a carafe. It often takes a lot of effort to get to stains in narrow-necked containers. There are several simple solutions to this problem that can be done at home. You just need to adhere to certain rules.

Washing the bottle: known rules

Place the bottle in warm water and pour warm water inside. In this case, the sediment will fall away faster, all that remains is to drain it. After the wine bottle has dried, you can repeat the procedure or try a different method. Alternating chemical exposure with rinsing with warm water is good for cleaning. When removing plaque from the inside, you can turn the bottle over. The sediment will fall off under its own weight. But sometimes this is not entirely convenient if the glassware is huge and there is not much space. It is worth considering that glass bottles, unlike plastic ones, do not absorb odors; the cork usually smells

It should be thrown away rather than reused. It is important to remember that glass is a fragile material. And large pebbles can scratch or break it

You should not experiment with them.

By following these simple rules, you can safely begin cleaning the container. But how and how can you wash a narrow-necked bottle if regular water doesn’t do the job? What available means can you use to wash it for sure? Over the long history of making homemade wine, many ways have been invented to clean hard-to-reach containers.

Let's consider several options:

• Ershik. A good old and indispensable item for washing any bottles. It copes well with hard-to-reach places and narrow necks. But in the case when the bottle is 19-20 liters, you should take a brush with a long handle and a more fluffy, dense and voluminous washing part.
• Water jet. That's also a good way. It’s good if there is a hose that fits into the neck, it can be directed towards the dirt. Under the pressure of the jet, the dirt falls away.
• Fresh dirt can be easily washed off with dishwashing detergent. Just pour it in there and shake it well. It cleanses fresh dirt well, but most likely will not cope with old dirt. In this case, you will have to settle the mixture.
• Soda. It will not give results on its own, but if you use the same brush, the result will appear.
• Vinegar. An excellent method for significant stains, but it takes a lot of time. With the help of vinegar, sediment is removed very well and the container is completely disinfected. But in order for the pungent odor to disappear after such cleaning, it is necessary to ventilate the bottle for a long time. If you have it, then this method is for you.
• Sand. Some people pour sand baked into a baking tray and pour water into it, shaking the bottle well. As a result, the precipitate disappears. The main thing is that the sand is fine and does not destroy the fragile container.

Non-standard methods

In addition to the above popular ways to wash containers, there are also non-standard ones. You can clean it with newspaper or cloth. The newspaper is torn into small pieces, thrown inside, filling about a quarter of the space, then water is poured. Wait for the paper to swell with liquid. Now you need to rotate and shake the bottle, trying to clean all areas of contamination.

With fabric it's a little different. First, they collect water, and clean water is diluted with a liter of river or swamp water. After this, they wait until the liquid blooms, and then insert a piece of fabric inside. They begin to drain the water, constantly straightening the piece of fabric along the walls. After this, gently pull the tip of the material. It turns out that she wipes all the walls. All that remains is to rinse thoroughly several times with clean water.

Another recommended method of cleaning is nettle. Well suited for those who live outdoors. First, water is poured in, the old dirt settles, then nettles are placed inside and the dishes are shaken, you can take a thin stick and rotate the water with leaves in a circular motion. Nettle copes well with pollution thanks to its leaves.

It is worth paying close attention to the cleanliness of the wine vessel. If suddenly there are some particles left there, then whatever you decide to pour into it will quickly spoil. It is highly not recommended to clean a glass container with cereal. It swells in water, and very small particles may remain, which will cause further rotting.

At the end of any cleaning, you should rinse the bottle several times with clean water. Then dry it thoroughly and close it. Wait two weeks and check if any dirt or an unpleasant musty smell has appeared on the walls. If any of this happens, then it is worth repeating the cleaning procedure.

Cleaning methods

You can clean the glass carafe yourself. However, this should not be done using a dishwasher - strong heat and vibration can cause irreparable damage to the jug.

1. Vintage items should only be washed in a plastic bowl to maintain their integrity. To do this, you need to place a soft towel or a small rubber carpet on the bottom. After pouring warm water, add detergent. Use a soft sponge to apply to contaminated areas.
2. You can wash the inside of the vase, but you need to take into account the intensity of the contamination. In this case, you should pour some water into the basin and add a cleaning agent. Then you need to hold the neck with your palm and shake several times. If stains still remain, you need to dilute salt and vinegar. This method can quickly get rid of plaque.
3. You can remove hard-to-reach stains using special products used for cleaning dentures. In this case, you need to pour water into the vase and add the product, then leave it overnight. The next morning, rinse the cleaned dishes.
4. Mustard powder will help remove water stains. You will need a small amount of water and a handful of mustard. Chat a little and the dishes will sparkle.
5. Vinegar is also used to remove hard-to-reach stains. You need to pour warm water into a vase and add 2 tablespoons of vinegar. After 30 minutes, rinse the vessel. If there are minor contaminants, you can put sand or eggshells inside the jug and then shake the vessel a little.

All methods are effective, the main thing is to follow the precautions and basic rules.

Each person has the right to choose how to clean a vase. However, drying and cleaning require proper techniques that must be applied consistently.

There is no centralized water supply in my private house, but we installed a water intake with a pump right in the underground, which creates good pressure, so that water flows from my tap. However, we are afraid to drink it just like that. And there is always boiled water in a glass decanter on the table. I change the water in the carafe often, but a cloudy coating still accumulates on its walls. And I want the glass to be transparent, like a tear!
