How to clean a thermos from tea plaque inside? This question ever arises for every owner. Even if you wash the flask well and thoroughly after use, this does not guarantee that an unpleasant dark precipitate will not occur. The peculiarity of tea and the tannins contained in it is that insoluble fractions simply have nowhere else to go, except to settle on the walls. And the longer the tea is in the thermos, the denser the film.

Causes of plaque

Phenols, tannins and theine alkaloid are responsible for tea layers. Thanks to them, the drink has an astringent taste. But with a decrease in temperature, the above substances lose their ability to form a solution, and they stand out in the form of an oily film. It shimmers with iridescent colors and has a pearly hue. In black tea, which is undesirable to brew for more than 5 minutes, it is formed more than in green tea.

If you continue to drink a cold drink, the film will enter the stomach, where it will not bring any harm to the body. But when you tilt the cup or thermos (which is inevitable), the film will end up on the walls and soon dry.

By the way, if you regularly observe a dense coating in a cup, drinking it hot, this is an indicator that the tea is excessively strong.

There is another version that the harder water you use, the more dense the plaque will be. The longer the cold tea stands, the denser the film on it will become. Therefore, if possible, use spring or bottled water.

How to clean tea plaque inside a thermos

How to wash a thermos from tea plaque inside? There are many ways in the world, but the result depends on what material the flask is made of. There are 2 types - glass or stainless steel. Glass is more fragile, but it is less capricious in care.

But there is always a cleaning agent in the house, because their choice is quite wide. All the recipes listed below are for the most common thermos volume - 750 ml. If you have more dishes - increase the dose.

Vinegar, citric acid or lemon

In this case, the acids contained in these substances “work”. The only thing is that with them the question - how to clean a metal thermos from tea plaque - will not be solved. Acids are quite aggressive, so they negatively affect metal, and even stainless steel. Nothing will happen to the glass.

Any vinegar(natural or synthetic), with a concentration of 6-9%, acts as a solvent. It should be placed in a thermos (one-third or half), pour boiling water (or boil the entire composition), close and leave for a couple of hours. There is an option to pour vinegar undiluted (but not essence) for a shorter period. Acetic acid is hygroscopic and will absorb all unpleasant odors along the way. Then drain the liquid, wipe the walls of the flask and wash well.

The most environmentally friendly way than to clean a thermos from tea plaque: cut into small slices lemon, pour it with boiling water in a flask and hold overnight. This method is also good because the bad smell will also disappear.

Lemon acid- an inexpensive (along with soda) and effective way to wash a thermos from tea plaque. Pour a couple of tablespoons (possibly with a slide) of acid into the dishes, fill with boiling water and (depending on the degree of stratification) let it stand for several hours or longer. Rinse the flask under running water and, if any stains remain, repeat the procedure again.

Sodium bicarbonate is used as a gentle, mild abrasive in both types of flasks, and is considered a quick way to clean the inside of a thermos. Apply baking soda to a wet kitchen sponge and go over the walls thoroughly. If you have a deep and narrow flask, then no fingers will reach the bottom. You can use a dish brush or a stick (for a sponge, pushing it deeper).

Strong or dense pollution will not succumb to soda the first time, and then another option should be used, with soaking.

Groats

Here is the answer to the question: “How to clean a metal thermos from tea plaque?” Groats remarkably eliminate plaque in stainless steel flasks. Here barley, peas or rice act as an eco-sponge. Swollen from boiling water, the porridge becomes loose and cleans the surface well. Just a few tablespoons of raw grains are enough, and a couple of teaspoons of soda are also added to enhance the effect.

Pour boiling water over barley, close the lid and leave for 30-60 minutes. Then shake the thermos well without opening it, and walk along the walls with a sponge. Don't forget to throw the contents in the trash.

Carbonated drinks

You probably already know that Coca-Cola, Fanta or Sprite, beloved by millions of children, remove limescale from the kettle. In the same way, these undiluted cleaners remove tea deposits. Coca-Cola works especially well. Orthophosphoric acid contained in drinks simultaneously removes rust, is used for etching teeth in dentistry and when soldering metals.

If you change your mind about drinking this wonderful drink inside, bring it to a boil, pour it into a thermos, close the lid and leave for a while (or until the morning).

White

Sodium hypochlorite is an excellent disinfectant, bleach and antibacterial agent. But use it, especially concentrated, should be used with caution. White contains aggressive chlorine, which will cope with plaque, but at the same time can damage welds, rubber gaskets or corrode plastic. And you will get a clean thermos that will not perform its main function and keep warm. Therefore, it is impossible to pour whiteness inside in its pure form.

But by applying whiteness diluted with water (1: 1) to a sponge, you can wipe the glass flask. Thus, any musty and unpleasant aroma "wins". Then the thermos should be thoroughly washed with soap and dried for a long time in the open. But especially sensitive noses will still smell a foreign smell for some time.

Ammonium chloride is an aggressive substance with a very pungent odor. It will remove bad smell and plaque, but at the same time it can corrode a stainless steel flask with prolonged contact. With a mixture of ammonia and chalk applied to a sponge or cloth, the inner surface of the glass flask is well cleaned, the main thing is not to soak and do it quickly.

How to remove the smell

Sometimes it seems that the flask is cleaned perfectly, but the unpleasant smell is still present. In this case, with absolute certainty, it can be argued that the case is in the lid. If it is made of natural cork, then it absorbs odors best. And it is necessary not only to wash the thermos from tea plaque, but also to periodically decontaminate the cork.

1. Natural cork, and plastic with rubber bands can be kept in a concentrated saline solution for several hours. The natural cork is poured with hot salt solution (but not boiling water) for several minutes.
2. Never leave a tightly closed thermos. Even a washed and dried flask will “suffocate” and an unpleasant odor will appear in it. And the remaining few drops of moisture will lead to the appearance of mold, fungus and mustiness.
3. Mustard will help eliminate the smell. Its large tablespoon should be diluted in boiling water and pour this liquid into a container. Turn the thermos horizontally and change its position several times so that the mustard touches all the walls of the flask. And you will solve 2 problems at once: how to clean a thermos inside from tea plaque and a disgusting smell. Do this periodically, arranging the prevention of your heat-insulating dishes.

What can not be used to clean a thermos

How to wash a thermos inside from tea is undesirable? Active substances based on chlorine (Domestos, Toilet duck). They are not intended for processing food surfaces. And do not even try to use them in a metal flask. Not only is there a risk of spoiling the dishes, you will also get a drink with an unpleasant aftertaste.

Harsh abrasives (metal brushes, scrapers, crushed eggshells, sand) may clean the surface, but will definitely damage the polished walls in both types of flasks.

Prevention of plaque and odors

One of the main ways to descale a thermos is not to create it by drinking hot tea right away. The longer the drink sits, the more plaque forms on it. Tea that has stood and drunk after 12 hours has guanidine in its composition. It makes the heart beat faster, increases blood pressure and causes euphoria, which is why the infamous chifir is so loved in prisons. Remember - it is undesirable to boil already brewed tea and drink it after a few hours.

Other rules:

• use soft water
• do not infuse tea for more than 15 minutes,
• do not drink yesterday's drink.

The most important prevention of unpleasant odor is drying the thermos. Never leave it closed or upside down to any surface. An open flask should be completely dry in the air and then any unpleasant smell (even from strong-smelling herbs absorbed into the walls) will not appear.

It is very convenient when there is a thermos. The range of its use is quite wide: you can make tea with honey and take it for a walk in the autumn park, or pour the broth inside and take it to a sick friend, and even kefir can be fermented in it.

And although we wash the thermos after each use, an unpleasant tea coating can still form. And what to do then? How to wash a thermos from tea plaque? But first things first.

Plaque

This wonderful, heat-retaining dish comes in two types:

• with a glass flask;
• flask made of stainless steel.

An unpleasant sediment easily settles on both the first and second types of this dish.

Not only is this terribly ugly, it also indicates that when you drink the next drink from a thermo mug, you will feel an unpleasant taste and smell.

Cleaning methods

In fact, it all depends on the degree of pollution.

With a weak touch, an ordinary lemon will help you. It must be cut into slices, put inside the dishes and pour hot water.

It is advisable to do this at night so that the cleansing mixture stands for as long as possible. In the morning, pour everything out and enjoy the clean walls of the washed thermos.

For more stubborn dirt, you can use pearl barley and soda. How it works: pour half a glass of cereal inside, add a few tablespoons of soda and half fill with water. Now you need to shake the thermos strongly. The cereal here will act as a kitchen sponge, and the soda will act as a cleanser.

Coca-Cola or Fanta can also clean the thermos from tea plaque inside. Heat one of these drinks almost to a boil and pour into a thermal mug. The lid does not need to be closed tightly. And be sure to leave it overnight. In the morning, the result will surprise you: no trace of plaque.

Well, the most effective remedy is cleaning with ammonia. It is poured into a plastic bottle and the cap is screwed on tightly.

In it itself, four holes should be made, into which the strings should be carefully inserted. The bottle must be turned over, and the threads lowered into a thermos. The lid of the dish must not be closed. Leave everything overnight, and in the morning rinse with any means.

The most radical remedy is to clean the thermos from tea plaque with the help of whiteness. It is necessary to pour only a third, and add boiling water to the rest and shake thoroughly. Just remember to wash the thermos very well with clean water.

Well, a few recipes at the end:

• Wash the thermo mug after each use. You can pour one tablespoon of soda with any detergent and leave overnight. It also helps clean dishes.
• Pour a few teaspoons of citric acid with boiling water and leave overnight. In the morning, pour out the contents and rinse with clean water.

Methods for cleaning heavy dirt

If a stainless steel thermos is regularly filled with strong tea, and cleaning is not performed, a strong internal plaque forms, which is already more difficult to remove. Various household cleaning products can help here.

If you do not plan to use a stainless steel thermos in the near future, you need to dry it properly and leave it open so that an unpleasant odor does not appear

Here are some popular ways to clean the inside of a stainless steel thermos:

1. Lemon or citric acid. If the neck is wide enough, you need to carefully rub the inside of the flask with slices of lemon, and then wash and dry it. If the neck is narrow, then instead of lemon, you can use lemon juice or citric acid. Squeeze juice from half a lemon into a flask or take 1.5 tsp. acid and cover with boiling water. Shake well and leave for an hour or overnight, depending on the thickness of the plaque. Remove residue by rinsing with cold water.
2. Mustard powder. Pour a few tablespoons of powder into the flask, pour boiling water over it and leave overnight. Rinse with cold water in the morning and pat dry.
3. Soda and vinegar. These two ingredients will help both wash and get rid of unpleasant odors. Apply a gruel of soda with water to the walls of the flask and leave for 7-8 hours. You can fill a thermos with vinegar and water in a ratio of 1:4, but it is best to use soda and vinegar together, leaving the mixture overnight, after which it must be washed and dried. Also, a good result is the use of soda along with rice or pearl barley. Take half a glass of cereal and 2 tbsp. baking soda, fill with hot water and shake well several times, then rinse and dry.
4. Coca Cola or Fanta. Everyone's favorite drinks can also help with plaque removal. Bring them to a boil and fill the thermos completely, leaving it open overnight, then rinse.
5. Means for cleaning dentures. If anyone in the house uses such a product, then it can also be used to cleanse stubborn dirt. Throw a few tablets inside the container, pour boiling water over and leave overnight. In the morning, wash and rinse with water.
6. Ammonia. This method is a little more complicated than the previous ones, as it requires preliminary preparation, but it is very effective. It helps to eliminate even the oldest traces of tea and coffee. Take a plastic bottle, make several holes in the lid and pass long threads through them. Pour alcohol inside. Fix the bottle vertically above the flask so that the alcohol can drain inside, and leave it overnight. Rinse in the morning with plenty of water and pat dry.
7. "White". Using this detergent is the fastest and most effective way to clean. In a ratio of 1:3, mix the liquid with hot water and pour into a thermos. Shake and then rinse well.

How to clean a thermos from tea plaque? After all, tannins accumulate over time on the walls of the flask, turning into a decent film thickness. What people just don’t come up with, wanting to get rid of this plaque and unpleasant smell in a thermos. By the way, regular washing does not really help. Over time, such a byaka will still appear on the inside of the flask.

Therefore, today we will consider the most common ways to clean a thermos from tea plaque. At the same time, let's think logically.

lemon and juice

Recipe. Squeeze the juice of 1 lemon into a thermos, cut the pulp along with the skins there. Pour boiling water over and leave overnight. Just rinse with clean water.

Reality. This procedure practically does not remove tea plaque. If only the freshest and weakest, the oldest and densest remain in place. But there will definitely not be an unpleasant smell.

What to do. Lemon juice does not need to be diluted with water for it to work. It must be concentrated. True, then the exposure time must be reduced to 15 minutes to avoid internal corrosion. The procedure will require only 2 lemons. And do not forget to shake the thermos often so that the juice is distributed along the walls.

Soda

Recipe. In a thermos pour 2 tbsp. l. baking soda, pour boiling water to the top, leave overnight. Rinse in the morning with clean water and dry.

Reality. The method copes well even with an old tea raid (usually after 2 attempts), but there are some additions.

What to do. Do not use boiling water! It instantly extinguishes soda, turning it into an inactive substance. It is better to take water with a temperature not higher than + 60 ° C. In this case, the soda will not dissolve, but will remain a cleaning abrasive.

To improve the cleansing properties, it is recommended to pour a couple of tablespoons of any raw cereal inside. In this case, the liquid should be no more than half the volume of the flask. Now you need to tighten the cork and shake the thermos with the contents well. After 5 minutes, repeat the procedure. You can do this a few more times, especially if your thermos has never been cleaned.

After that, it remains only to pour the smelly liquid into the toilet bowl, then thoroughly rinse the flask with plenty of warm water.

Vinegar and soda

Recipe. Pour 3% vinegar into the flask, add 3 tbsp. l. baking soda. Leave overnight, then rinse with clean water.

Reality. The advice was clearly given by a man who never made himself a fizz as a child. These two substances, reacting with each other, are completely neutralized. And why is there to withstand the whole night an absolutely useless liquid? And there are plenty of sources that rewrite this recommendation word for word without even thinking. Plus, there is still no warning about the strength of the reaction anywhere. It’s not enough to put a thermos in the sink, you need to put it in the bath! For the departure of dirty foam occurs as a fountain.

What to do. Choose one thing. Or clean the thermos with vinegar, any soda. Mixing these two components is only a transfer of time and money. Or make yourself a fizz!

Vinegar

Recipe. Pour boiling water into a thermos, add 1 tbsp. l. vinegar essence. Leave overnight. Rinse well with water in the morning.

Reality. The method works very well. True, instead of a hash with acid, you can simply pour 3 or 6% vinegar into the flask. Then you will definitely not be mistaken with the concentration, because the volumes of thermoses are different for everyone.

What to do. You can not leave the liquid inside for the whole night. An hour of processing will be enough. To heighten the effect, do not add acid to the very top. Leave about a third of the volume free, throw a small piece of a hard sponge inside. Then screw on the cork and shake.

And do not be afraid of an unpleasant pungent odor. If you give the flask a good rinse and then dry it open, the vinegar flavor will quickly evaporate.

Coca Cola

Recipe. Pour boiling soda into a thermos, leave overnight. Rinse in the morning with clean water.

Reality. Well, why these daily soaks? Another week would be advised to leave. The alkali contained in the drink will perfectly cleanse the plaque from tea in just an hour. And in 12 hours, it will begin to corrode directly the metal of the flask itself.

What to do. Coca-Cola does not need to be boiled. It works well even at room temperature. Pour the drink into a thermos, cover the neck with your palm. And give it a good shake over the sink. Do not try to twist the cork! Inside there will be pressure from gas bubbles. Well, if there is just a fountain when you unscrew the lid. But it can break the seams of the flask. Repeat the procedure 3 times within an hour. Rinse the thermos with cool water afterwards.

White

Recipe. Concentrated whiteness is poured into the flask, left for several hours. Then rinse thoroughly with plenty of warm water.

Reality. A method for real extreme sportsmen. Whiteness does not clean the plaque from tea in a thermos. It doesn't even dissolve. She just bleaches it. And the unpleasant amber will remain for a long time. Do you like white tea? Then feel free to take the method into service.

What to do. Leave whiteness for other purposes. Or at least thoroughly rinse the thermos with cold water instead of warm. So the smell of chlorine will disappear much faster.

Ammonia

Recipe. Pour into the flask 1 tbsp. l. ammonia, add warm water to the top. Leave ... that's right, overnight. Rinse after.

Reality. Diluted ammonia by itself will not clear the plaque from the tea, it will only soften it. And the stench will dilute in the kitchen such that the eyes on the forehead. It is also advised to create an incomprehensible structure from cork, ropes and a bottle. The bottom line is that the stench will still be there. And it makes no sense.

What to do. Sprinkle a little ammonia on the bottom of the thermos and tighten the cork tightly. After 6 hours, we open it, take a brush and with light movements remove absolutely the entire plaque. In the absence of this, we pierce a sponge for washing dishes with a fork. We act similarly.

At the end - water procedures and drying with ventilation.

How to clean a thermos from tea plaque - you now know. Take note of any suitable recipe, act and admire the cleanliness of your heat-saving assistant.

Video: how to clean a thermos

Stainless steel inside the thermos easily absorbs various odors, it is also prone to the formation of plaque from tea or coffee. Contamination leads to the fact that the storage of drinks and food in these dishes becomes almost impossible. Scale, deposits from drinks and an unpleasant lingering smell will spoil the taste of food. It is important to know how to clean a stainless steel thermos inside without damaging the surface of the product and extending its service life.

Remove plaque and scale

Tea plaque is the most common type of staining on stainless steel cookware. On the walls of a thermos, it can form in just one hour. If the thermos is not cleaned of dirt in a timely manner, the plaque layer will become thicker, and it will be much more difficult to deal with it.

Hard water or irregular care of thermal dishes are also reasons for the formation of unpleasant dirt. There are many simple tools that will help in the fight against plaque from tea or coffee, as well as clean the thermos from scale and food debris without damaging the inner surface of the product.

Lemon acid

Food acid is a fairly effective and at the same time affordable tool for treating stainless steel products. A solution of citric acid is able to cope not only with a touch of tea or coffee, but also eliminate the musty smell. You can clean the thermoware with such a tool as follows:

• Pour two teaspoons of citric acid crystals into the vessel.
• Crystals should be poured with boiling water, and the thermoware should be closed with a lid.
• Leave the liquid in a thermos for 24 hours.
• After the cleaning procedure with food acid, the flask must be thoroughly washed inside with soapy water and dried.

Acetic essence

Vinegar will quickly and effectively help get rid of tea plaque. The process of cleaning a thermos with vinegar solution is quite simple:

• 9% vinegar should fill one fourth of the flask.
• The remaining three fourths are poured with warm water.
• Close the thermos tightly with a lid and shake a couple of times.
• The vinegar solution must be kept in a thermal container for at least 2 hours. In this case, every 20 minutes it is necessary to shake the vessel.

sodium bicarbonate

Baking soda will help not only clean the product from plaque and scale, but also save it from bad smell and germs. To wash a thermos with soda, we need:

• soda (3 tablespoons);
• steep boiling water;
• coarse salt (3 tablespoons).

Pour sodium bicarbonate into a thermos, pour boiling water over it, tighten the lid and hold for 6 hours.

After the infusion procedure, you need to add coarse salt to the soda solution, close the stainless steel product tightly again and shake it several times. When shaken, the salt crystals will help to completely clean the plaque from the walls of the flask.

baking powder

Baking powder contains substances such as baking soda and citric acid. Due to this composition, baking powder is an effective tool in the fight against plaque. In order to clean the thermos in this way, it is necessary to place baking powder (3 tablespoons) in a flask and pour warm water.

The thermos is closed and infused with the solution for 2-3 hours. After that, the liquid is drained, and the flask must additionally be rubbed with a sponge and rinsed thoroughly.

Rice and pearl barley

Rice has abrasive properties, so the groats can be used to clean a thermos. Pearl barley also absorbs dirt well and removes plaque. Clean the thermoware with cereals as follows:

• Pour half a glass of clean rice or barley into the flask.
• Groats need to be poured with boiling water to the edges of the flask. To the resulting mixture, you can add sodium bicarbonate (1 teaspoon with a slide).
• Screw on the lid, shake several times and leave for 2 hours.
• Every 15 minutes it is recommended to shake the thermos, which will help to clean the walls from scale.
• Pour out dirty water with cereals, and rinse the thermos well.

Carbonated drinks

There are quite non-standard means for cleaning stainless steel thermoses, such as soda. Due to its composition, Coca-Cola easily copes with the removal of tea plaque. There are two ways to clean a thermos with soda:

• Coca-Cola should be filled to the brim with a thermos and left in a warm place for 10 hours without covering the dishes with a lid.
• Soda must be boiled, then poured into a flask. Close the thermos with a lid (not very tightly) and shake several times. Leave the liquid in the thermos for 10 hours.

Bleach

Another non-standard tool that can be used to clean a thermos from heavy dirt is "Whiteness". You can wash the thermos with "Whiteness" as follows:

• Bleach is poured into a thermos. The liquid should occupy three fourths of the total volume of the flask.
• To "Whiteness" add warm water to the edges of the flask.
• The thermos is tightly twisted with a lid, shaken thoroughly and left for an hour.
• Then it is necessary to drain the solution, wash the flask with soapy water and rinse thoroughly.

It is advisable to resort to this cleaning method only in case of urgent need. "Whiteness" is a rather aggressive agent that can ruin the flask, or dissolve the rubber o-rings.

Another significant disadvantage of this method is a sharp, difficult to remove chloride odor. Thorough rinsing of the flask with cold water can help to get rid of the smell of bleach after cleaning the Beliznaya thermos.

Ammonia solution

Old, stubborn stains can be dealt with with ammonia. This method of cleaning a thermos is a little more complicated than the others, but it is quite effective. To clean the thermos with ammonia, you must first build some kind of dropper.

To do this, take a plastic bottle, which should be smaller in volume than a thermos. Three small holes are made in the cap of the bottle through which threads are passed. At the bottom of the bottle pour ammonia. Such a semblance of a dropper must be lowered with a lid down into the flask. Alcohol will slowly flow down the threads, and, evaporating, will corrode strong contaminants.

Eliminate bad odor

Almost all the products that are used to clean the flask from plaque additionally fight bad odors. But sometimes, after cleaning stainless steel thermoware from plaque and scale, an unpleasant odor remains inside the product. In this case, it is necessary to resort to additional processing, using other cleaning methods:

• Salt. Salt can also be used in the fight against tea plaque, but still this tool is more suitable for eliminating unpleasant odors. To prepare a steep saline solution, you need to dilute 4 tablespoons of salt in 1 liter of boiling water. The required amount of liquid is poured into a thermos and kept for 10 hours. After that, the solution must be poured out, and the thermoware thoroughly rinsed.
• Lemon juice. From one lemon you need to squeeze the juice, finely chop the pulp, and grate the zest. The resulting mixture is placed in a thermos, poured with boiling water, tightly closed with a lid and left to infuse for 2 hours.
• Soda. Drinks such as Sprite or Fanta do an excellent job with the smell of dampness. To do this, boil the lemonade, pour it into the flask to the brim, close the thermos with a lid not very tightly and leave for 12 hours.

• Dry mustard. Three tablespoons of mustard powder must be poured into a thermos, pour boiling water, close the lid and leave for 10 hours.
• A solution of soda and vinegar. Each component is separately used to clean the thermos from plaque. A more aggressive and effective method will help to cope with the stubborn odor. To do this, baking soda must be mixed with vinegar in a one-to-one ratio (for a small thermos, it will be enough to take 3 tablespoons of soda and vinegar each). The resulting mixture is placed in a flask, poured with boiling water, closed with a lid and kept for an hour.

After the cleaning procedure by any of the above methods, certain products that absorb odor well can be put in a dry thermos for a while. It can be a slice of stale black bread or a couple of tea bags with mint. Powdered charcoal also perfectly absorbs bad odors.

Getting rid of fungal growths

If the thermos is kept closed for a long time, mold can form inside. The fungus is one of the most unpleasant and difficult to remove types of pollution. You can remove the fungus in thermal dishes using household chemicals.

There are many dishwasher cleaning tablets and gels on the market. Such funds will help get rid of fungal formations in a thermos. But it should be noted that this method is not suitable for all thermal dishes. This method should be used with extreme caution and only when absolutely necessary.

Using this method to remove mold, it is not necessary to subject the inside of the flask to additional mechanical stress. In other words, do not rub the thermos from the inside with a brush or brush. After treating the dishes with a cleaning agent, it must be repeatedly poured over with boiling water and rinsed thoroughly.

To avoid further formation of fungus inside the flask, the thermos must be thoroughly washed and dried well after each use. It is worth storing thermal dishes only in an open form.

To prevent the formation of plaque from tea and an unpleasant smell from food in a stainless steel thermos, such a product must be regularly looked after. After each use of thermoware, the flask and a cover need to be washed out carefully. You can wash such a product with ordinary soapy water or dishwashing gel.
