The use of Domestos in disinfection and whether the remedy helps against coronavirus

Where is it used?

Domestos is a universal detergent. It can be used to wash stoves and bathtubs, floors and window sills, and almost anything that can be wet cleaned.

Unfortunately, harmful bacteria and microbes live not only on the street, but also in the house. It is very important to keep your home clean. We have already talked about this a little above. Now let’s take a closer look at how you can use Domestos. Instructions for use are given in the form of advice, according to what is being washed or cleaned.

Toilet

The cleanliness of the bathroom must be carefully monitored and dirt must be kept away. Each family member and guests visit the toilet several times a day. A large number of harmful bacteria accumulate within a day. To avoid infections, you should use a disinfectant, such as Domestos. The instructions for use for the toilet, compiled by the manufacturer, contain the following advice on this matter: buy a special composition for cleaning toilets (the hole and cap of this Domestos are at an angle of 45 degrees). Apply the gel under the rim, pressing lightly on the sides of the bottle. As a result, the toilet bowl will be treated with gel all around. It would be ideal if on weekdays, while everyone in the household is at work or school, you clean the toilet and leave it like that until everyone comes home. Do not wash off immediately after treatment.

Using Domestos for cleaning the toilet

Domestos for bathroom cleaning is sold in special bottles, the spout of which is bent at an angle to the main container. This allows you to quickly and without getting your hands dirty to apply the product under the rim of the toilet bowl, where most of the dirt accumulates. Due to its gel-like consistency, Domestos lingers on the surface of the earthenware for a time sufficient to degrease and disinfect it.

To treat the toilet bowl, turn the bottle with Domestos upside down and, lightly pressing on its walls, apply the gel along the inner perimeter of the toilet bowl. Ideally, this should be done at night. But you can carry out the treatment in the morning, before everyone in the household leaves for the day’s errands. The main thing is that the composition remains on the surface of the bowl for several hours - during this time it will have time not only to disinfect, but also to slightly whiten it.

Important! You should not use Domestos on the toilet every day - it is enough to apply the composition to the plumbing a couple of times a week.

Sink and bath treatment

The toilet is far from the only potential breeding ground for bacteria in the apartment. Harmful microorganisms accumulate on the surface of any plumbing fixture, including the kitchen sink. Therefore, the bathtub, shower tray, as well as sinks in the bathroom and kitchen should be regularly treated with Domestos. For antibacterial, degreasing and whitening effects, it is enough to apply the composition to the surface of these items for 3-5 minutes.

Distribute the product evenly using a sponge. Rub particularly dirty areas - rust stains, water deposits, etc., and after a while, wash the entire treated surface of the plumbing with cool water and wipe dry.

Advice! On each bottle of Domestos, the instructions for use advise applying this product only with gloves. Don't ignore this advice! This gel, especially undiluted, can severely damage the skin of your hands.

Surfaces of sinks, bathtubs, stoves

To keep the bathtub, sink and stove clean, apply the detergent we describe to the surface, rub with a sponge, rag or brush and leave for 5 minutes. Let the dirt soak into the applied product.

If there is rust, stains from burnt porridge or runaway milk on the surface of the stove, grease in the kitchen sink, deposits on the tiles, rub with a rag or brush until it is clean.

As the instructions for use for Domestos say: rinse off the cleaning agent after 5 minutes with warm water. And to clean the stove, rinse the rag/sponge. By the way, this product perfectly destroys not only bacteria, but also fungus.

Drains and plumbing

Do you know that you can pour Domestos undiluted into the drain hole and leave it like that for a few minutes? But in this way you can clean the pipes from grease, plaque, and bacteria. It will be enough to pour about 50-100 ml.

It is worth noting that for prudent housewives, stores sell 5-liter canisters of Domestos. Instructions for use are the same as for the bottled product.

The whiteness of things

It turns out that you can bleach clothes, towels, and bed linen! Domestos' instructions for use mention this. You can see a photo of this wonderful product in this article. Please note that there are several options: classic (blue) and flavored.

Let's get back to things. As we just said, there are products with a pleasant aroma. They can be used for linen. Take 5 liters of hot water, add 1 capful of product, let the laundry sit for 45 minutes. Then just rinse, no need to wash with powder. You can leave the laundry overnight. But the scheme is different: half a cap of Domestos for 5 liters of water.

Caution doesn't hurt

Despite the fact that the product is ideal, it is unsafe. Try to clean Domestos so that children, animals, and disabled people cannot reach it.

It is advisable to carry out processing and washing with rubber gloves, as the product can cause irritation, allergies, and burns.

This cleaning product should not be used if there is a sick person with moderate or severe asthma living in the home, as the fumes may cause a suffocation attack.
