How to clean the kettle with citric acid how much to pour

The reason for the appearance of scale and its consequences

Scale is a white or yellowish precipitate formed with boiling water inside an electric kettle. At first it is soft and is cleaned with a regular sponge. Over time hardens and the layer becomes thicker.

Where does it come from

The reason for the appearance of scale is the calcium and magnesium salts dissolved in water, the so.called hardness salts. Most often we are dealing with carbonate stiffness, it is due to the presence of magnesium and calcium bicarbonates. These substances appear due to the dissolution of gypsum, limestone, dolomite. Liquid from underground sources and wells is always tougher than fresh water from the surface.

Reference. “Hard” water began to be called due to the properties of tissues, painted with soap based on fatty acids. Fabric painted in water containing a large amount of salts, to the touch is a tougher.

At temperatures above 60ºС, easily soluble bicarbonates are converted into carbon dioxide, water and insoluble calcium or magnesium carbonate, which settles on the surfaces of water heating devices.


The thermal conductivity of the gross growths is lower than that of metals. Heating elements are covered with peculiar thermal insulation, which leads to the following:

The scale in the teapot worsens the taste of drinks, sediment particles fall into the cup. All this reduces the pleasure of tea drinking or a morning cup of coffee.

On a note. From the point of view of medicine, the use of water from a kettle does not harm health.

Cleaning methods

There are two ways to remove deposits from surfaces: mechanical and chemical.

Mechanical cleaning is harmless, but has a number of disadvantages:

  • risk of damage to metal and electric heaters;
  • labor intensity and time of time;
  • the inaccessibility of some surfaces due to the complex shape of the parts.

Clean the electric kettle with chemistry quickly and simple: insoluble deposits turn into soluble forms and are washed out of the device.

One of the most affordable and safe tools is considered citric acid. How to use it against scale. we will tell you later.

How to clean an electric kettle with citric acid

The action of the substance is based on an exchange reaction with insoluble carbonates. In this case, easily soluble citrate of calcium and magnesium, carbon dioxide and water are formed.

On a note. Citric acid and its salts are quickly washed out when rinsing and are not dangerous for the body, especially in those microdoses that may remain after processing.

Options for cleaning electric kettle with citric acid: with boiling, without boiling and cleaning with lemon.

With boiling

This method is used with a significant number of scenes. The more sediment, the more acid crystals dissolve. Depending on the thickness of the layer of deposits, one or two powder bag is taken (20-40 g).


  • Fill the kettle with 2/3 clean water, add cooked citric acid.
  • Turn on the device and boil.
  • Leave the solution in the kettle for 5-6 hours.
  • After that, drain the liquid, if necessary, remove the softened remains of the deposits with a sponge.
  • If the scale layer is too thick, repeat the procedure again.
  • Rinse the device thoroughly from the inside, pour fresh water and boil, then drain.

Without boiling

With regular cleansing the device from scale, citric acid can be used without boiling:

  • In 1.5 liters of warm water, dilute one bag.
  • Pour the mixture into the kettle and leave for 4-5 hours or at night.
  • Pour the solution and rinse with water.
  • Pour clean water, boil, drain boiling water.

Cleaning with lemon

An ordinary lemon will help to get rid of the sediment in the kettle. This tool is absolutely safe, although it will cost a little more than the use of crystalline citric acid.

A small amount of scale will be cleaned by half lemon. If the device has not been cleaned for a long time, you will have to take a whole fruit:

  • Cut the citrus with a peel into thin circles.
  • Pour the kettle with water by 2/3, lower lemon slices.
  • Boil the mixture 2-3 times.
  • Drain the liquid along with the remains of the lemon, rinse the kettle.

The reasons for the appearance of scale

Salt plaque on the walls of the teapot appears if water water is poured into it. For a long time they have been talking about its low quality and the presence of extraneous impurities. If boiling allows you to get rid of microorganisms, then salts begin to decay due to high temperature with the formation of a solid sediment. It is deposited on the walls, and each time it becomes more and more.

It will not work to remove the scale with conventional agents or sponge, as it bits to the walls of the dishes. It turns out a very solid plaque consisting of metals salts. For example, a yellowish-red sediment indicates an excess of iron salts, and milk-white-calcium or magnesium.

Scale reduces the thermal conductivity of the device. If this is ordinary dishes heated on a gas stove, then it is almost imperceptible that the time to boil water has increased. But in an electric device the scale covers the heating element, which is why it overheats. The energy consumption and risk of damage to the device is increasing.

In addition, scale causes people’s health harm. If you do not work out from it, with each boiling, small particles break off and remain in the water, and from there fall into the stomach. These solid mineral salts are not digested. They accumulate in the organs. Such particles can cause the development of urolithiasis or gout, often become one of the causes of osteochondrosis. Therefore, it is necessary to get rid of the scale in the teapot in a timely manner.

After a long use in the kettle, a scale appears, it is difficult to cope with which without special means

Ways to clean

For those who do not want to use chemicals, there are simple and effective folk methods. Most often, it is recommended to clean the kettle from the scale with citric acid. This tool reacts with salts, making them softer. Because of this, they easily lag behind the walls.

Such cleaning is safe for the device and human health itself. The product is suitable for any type of dishes. It is easily washed out, and even if its traces remain, their entering the human body will not harm them. Therefore, cleaning the teapot with citric acid is so popular among housewives.

The solution of powder or lemon juice will be equally effective. But the use of fruits will be more expensive, because they will need several pieces.

Before proceeding, you should find out how to clean the kettle from scale with citric acid correctly. In order not to spoil the dishes and not harm yourself, it is recommended to observe precautions:

  • It is advisable to put on gloves in your hands;
  • Be sure to observe proportions;
  • If acid is used in powder, it cannot be poured into the dishes at once, first water is poured;
  • If the plaque does not lag behind, it is forbidden to clean it with a knife or metal washcloth, you can use a wooden spatula;
  • After that, it is necessary to rinse the device and boil it several times, draining the water.

Depending on the material

Teapots are made from different materials. In addition, they differ in the method of heating. there are electric and ordinary. It is believed that at home it is easiest to clean them with lemon acid. This tool acts softly and can be used for any type of dishes:

  • Metal utensils can be boiled for a long time with citric acid, the surface from this will become more shiny. For such dishes, it is allowed to prepare products with the addition of vinegar or soda.
  • The electric resistant glass electrical device is also easily cleaned with this tool. You can boil it with acid, the glass will become transparent and shiny.
  • Thermopote is a metal electrical appliance. It is difficult to wash it in the usual way. But citric acid can make it cleaner, and also relieve the scale.

It is not recommended to use concentrated acid solutions to clean enameled and plastic surfaces. Such funds can damage them. Therefore, you should study how to clean an electric kettle from scale if it is made of plastic. This tool can be used, but not more than 2 teaspoons. It is not recommended to boil it. just pour inside and leave for several hours.

There is an effective recipe with lemon acid and vinegar, it removes any, even thick plaque. But you can use it only for ordinary metal teapots:

  • Pour water to half a container.
  • Add half a glass of ordinary vinegar.
  • Leave for 20 minutes.
  • Pour a tablespoon of acid, stir.
  • Boil for half an hour.
  • Turn off and leave to cool.
  • After that, wash with ordinary detergent.

After you cleaned the kettle of scale with citric acid, it is necessary to boil water at least three times, draining it each time.

Depending on the degree of plaque

It is easy to clean the kettle with citric acid, but you should know in what concentration it is used. It depends on the thickness of the plaque:

  • For prevention, a teaspoon will be enough;
  • If the precipitate is thin, you need to dilute 10 g in a liter of water;
  • With a thick layer of scale, from 20 to 40 g of powder is required.

There are two methods of cleaning: soaking and boiling. It is easiest to clean the kettle of scale with citric acid with citric acid, if a little plaque. You need to dissolve the product in water, pour and leave for 4-5 hours.

For the preparation of the solution, 1 liter of water and 1-2 of the acid bag are required. First dissolve the powder, then pour it into the dishes. Leave the product for at least 5 hours, better at night. Then pour the solution, rinse the dishes and boil with clean water.

This method has two main advantages: it acts softly, suitable for any surfaces. But the method will be effective only with small pollution. Therefore, if it does not work, you can use another way.

When the scale layer is dense and thick, the solution must be boiled. Under the influence of high temperature, salt is destroyed faster. But you need to observe precautions, since pairs can be toxic. This cleaning method is more complex, you need to follow all the recommendations for sure:

  • Wash the device with ordinary detergent and soft sponge.
  • Pour water at least 2/3, but not to the edges, otherwise it will splash out when boiling.
  • Pour 1-2 packages of powder, stir thoroughly.
  • Put to heat up. It is desirable that water boils 10-15 minutes. If the kettle is electric, then 2-3 minutes.
  • After that leave the dishes cool down.
  • Pour water, clean the sediment with a wooden spatula or sponge.
  • Wash the cleaned kettle, boil clean water.

Cleaning machines with citric acid ��

If the sediment is old and boiling did not help, you need to make paste of soda, lemon and water acid. It is applied to contaminated places for the night. In the morning you need to pour water into the device and bring it to a boil.

Any dishes can be cleaned with natural lemon. You need to cut 1-2 fruits in circles, fill them with dishes and pour water. Then boil 10-15 minutes. This method is more safe for health. In addition, it is not necessary to boil clean water after it, and the dishes acquires a pleasant lemon aroma.

Which teapots can be cleaned with citric acid

Not every material from which the kettle is made allows you to use citric acid to combat a scale.

It is extremely undesirable to use citric acid for aluminum tank, since when heated aluminum, it reacts, and its insignificant dissolution occurs.

Important! Pay attention to the enameled coating. If there are cracks or chips in it, you should not use the method of cleaning with citric acid.

Of steel

Color is important in steel dishes. Air oxidation protection is achieved by introducing chromium into metal. A protective oxide film is created on the surface that prevents the formation of rust.

How to Clean With Citric Acid Safely and Efficiently

Citric acid is not considered so strong as to spoil steel, but if the film has already worn out, after boiling inside the kettle, steel will darken, iron citrate forms. It will not be possible to use such a kettle. It is better not to boil steel utensils, but to warm up a little.

The thermal conductivity of the scale is less than thermal conductivity of steel, therefore, even if there is a thin layer of soot, it is possible to form a large thermal resistance, which often leads to a strong overheating of tubular electric heaters.

The advantages and disadvantages of the method

Advantages of cleaning with citric acid:

  • The substance is sold in any grocery store;
  • low cost;
  • convenient and simply in use;
  • effective;
  • dishes acquires a pleasant lemon smell;
  • additional disinfection of kitchen utensils;
  • small consumption;
  • Environmental friendliness.
  • over time, acid destroys metal and heating elements;
  • rubber seals from acid exposure soften, cracks appear in them;
  • You have to thoroughly rinse the dishes and boil several times after use;
  • When pollution, it is necessary to use more than once.

How to clean the kettle of scale: 5 effective methods that you may not have guessed about

Scale formed on the inner surface of the kettle is quite frequent. And in particularly neglected cases, it can also appear outside the kitchen utensils. And since modern dishes are in most cases glass or has a mirror surface, it is quite difficult to serve it. Indeed, when using abrasive cleaning products, you can leave quite visible traces on the surface. How then you can clean the emerging deposits.

Lime plaque is formed due to hard water used for drinking purposes. Therefore, in order to prevent the formation of a raid in advance, it is worth putting special filters and softeners. This will allow you to get prepared water at the initial stage and thereby there will be less plaque on dishes and kitchen appliances.

In addition, the lime plaque that appears not only spoils the appearance of the equipment, but can also harm it. Since, due to its structure, the thermal conductivity of heating elements is reduced, which in turn negatively affects them. And under the lime coating, rust is more actively developing. When a raid appears, you should think about its cleaning, otherwise you will have to completely replace the dishes in the near future.

The very fact of the appearance of lime plaque on the dishes should make you think, because a large consumption of such water can harm the human body. This can especially affect the elderly and people suffering from urolithiasis. The color of the plaque can suggest what kind of salt is in an excess and will allow you to choose the right cleaning filters. So, when the red.haired plaque appears, it indicates a large iron content, and white indicates. Overflow of chlorine.

But most do not use even the simplest filter, so the scrap on the dishes is a frequent phenomenon. How to quickly and completely get rid of it without damaging the dishes.

Perhaps the most common way to clean is the use of citric acid. For me it is also the most effective and painless. Including citric acid can also be used to clean the washing machine.

The method is simple and reliable. There is enough for a kettle and one teaspoon with not a strong raid, and if probably, you can two. Pour water and turn on for boiling. When heated, it will immediately see how the scale begins to exfoliate and bubble. The higher the temperature, the faster the process will occur. If the kettle is turned off before the entire scale disappears, then you can wait, or after some time turn on the boiling again. After processing, we wash the kettle and use for its intended purpose.

I clean the washing machine every half a year using citric acid. Since a large layer of scale can form on the heating shadow and it is not visible while ten inside. We fall asleep a little more than citric acid and turn on the washing mode with boiling.

If there is no citric acid, then you can use acetic acid or essence. Since the “lemon” may not be at the hostess, and vinegar always happens. Do not forget that with vinegar it is worth treating more carefully and if it is a 7-9% solution, then approximately 100 ml of liquid will be required, and when using essence, you can do with 1-2 tablespoons. Further actions are similar when working with citric acid, but a vinegar smell will appear during boiling in the room. Therefore, I recommend carrying out this operation in a well.ventilated room. And after using vinegar, rinse the dishes well.

Baking soda. Another miraculous way, but to make it turn out, you will have to dissolve 1-2 tablespoons in 0 in advance.5-1 liter of water. And only after that put on boiling. The cleansing properties of soda are slightly lower than in the first two methods of cleaning, but a pack of soda is in every family. It is stored for years in a cardboard box of light orange shades. Be sure to completely dissolve soda, otherwise after processing you can easily scratch the glass surface. And after processing, be sure to boil with clean water again.

Coca-Cola or Cola has become widespread and is used not only as a delicious sweet carbonated drink. It is used to clean rust, toilets and many other things. And for cleaning from scale, it fits perfectly. The composition of Coca-Cola includes orthophosphoric acid, which is contained in small quantities, but it is enough to influence the lime coating. Before use, you should wait for the complete disappearance of gas bubbles and only after that we boil the kettle. Orthophosphoric acid also contributes to leaching of calcium.

And last household chemicals, which will cope with any coating, but can significantly damage household appliances. So, for example, it can affect plastic or sealing rubber elements. Household chemicals can be either in liquid and powder.shaped option, so before use you should definitely familiarize yourself with the instructions. And in the case of powders, also carefully use the damage to the glossy or glass surface is simply inevitable. Usually, household chemicals are the most powerful removal lime coating completely and the first time.

Scale appears in any case, even when using prepared water, but in a much smaller amount. Therefore, prevention should be carried out in advance and not delaying, since in a small amount it is easier to remove it. Use prepared water and not a fact that the water that you buy in the store will be much better than a conventional tap, and even after filters. And do not leave water in the kettle for a long time, because during downtime a plaque forms and microbes appear.

There are also more exotic means of getting rid of plaque, for example, such as vegetable and fruit purification or brine from conservation of cucumbers. In both cases, acid forms from vegetables and fruits in the reaction. Such life hacks with a small raid will cope, but if there is no longer any other opportunity, then why not.

Money saving way to descale a kettle.

Removing scale with citric acid and soda

Drill soda enhances the effect of citric acid without boiling, so the method is suitable for all types of teapots and electrical appliances:

  • Dilute the granules in steep boiling water (1 t. l. 1 l).
  • Fill the kettle to the top. Leave for 15 minutes.
  • Gently pour soda (1 h. l. 1 l). The reaction will be stormy, put the kettle in the sink or deep pelvis.
  • After 20-30 minutes, drain the solution, rinse the body well with a soft sponge.
  • Boil clean water 2-3 times.

The use of lemon juice with soda can damage the open heating element of the electrical appliance. Also, do not use the method for cleaning dishes from copper or aluminum.

How to remove a thick layer of scale

In advanced cases, you can clean the kettle with citric acid with the addition of baking soda and vinegar. Sodium enhances the effect of acid, and vinegar makes the reaction powerful.

  • Pour boiling water into the dish (2/3 of the total volume).
  • Pour baking soda: 2 st. l. 1 liter of water.
  • Leave for 30–45 minutes.
  • Drain the spent water. Do not rinse! Part of the soda should remain to react with acid components.
  • Fill the kettle with 2/3 with hot water, dissolve acid (25 g per 1 liter of water).
  • After 30 minutes, drain the solution. Rinse the inside of the body thoroughly, trying to remove the softened part of the coat.
  • Dilute vinegar (70%) with hot water (100 ml per 1 l).
  • After 1 hour, rinse.

After such processing, the plaque becomes soft, pasty. It is easy to remove it from the walls with a regular sponge.

Master class-cleaning the kettle from scale: 7 of the most effective ways are offered.

The kettle after washing must be boiled, changing water twice to remove the remnants of cleaning products and an unpleasant odor from vinegar.

The method is suitable for washing glass teapots. It is also safe for stainless steel and ceramics. But using a recipe for removing a raid in an electric kettle is not worth. A similar combination of cleaning products can damage the plastic case and the heater.

The method of cleaning the scale with lemon in combination with soda and vinegar is not recommended for electric kettles, as well as for enameled or aluminum dishes.

How to clean a kettle from scale lemon

Cleaning with lemon to many seems costly manipulation due to the cost of citrus fruits. But you should think! The procedure will require not 1-2 fruits, the cost of which is small, and the benefit is maximum. Without harm to health, you clean the kettle, with a bonus, getting a pleasant aroma throughout the apartment.

Preparation for cleaning

To clean the kettle with lemon, you do not need to produce long and meticulous preparatory measures. It is enough to focus on two main components: water and lemon.

It is advisable to use the filtered water to use the valuable supply of citrus exclusively as intended.

While the measured liter of water is filtered, take a lemon. It is he who requires maximum attention.

  • Thoroughly using a special fruit tool, rinse the zest of 2 lemons.
  • Put citrus on a clean surface and roll several times. This will contribute to the intensive and rapid secretion of juice.
  • Take a cutting board that has a rim that prevents fluid of liquids outside the working area.
  • Cut the lemon into slices or mugs. Given the fact that boiling is carried out, the size of the pieces can be quite large.

All is ready. It remains to prepare a soft cloth or sponge.

Two lemons are used if the scale layer is thick or old. In other cases, one fruit is taken for the specified liter of water.


Advantages Flaws
Soft purification process Individual intolerance
Is washed out the first time Suitable for all materials
Safe, because citric acid is even eaten
Available value option
Cleaning the kettle to the state of the new
Even the ancient and thick plaque removes

The main thing is that when working with acid, do not forget about rubber gloves. In this case, the work will definitely end with a success.

Prevention of problems

Although most often, cleaning the teapot with citric acid is completely simple, it is better not to bring dishes or equipment to a critical state, because, as mentioned above, this can harm health.

There are 4 steps that will help keep the kettle clean as long as possible:

  • The use of clean water, for example, filtered or bottled. If this is not possible, then before boiling watering water it is better to give up.
  • Do not boil the same water several times, as this will increase the chance of the formation of scale.
  • After each use, the kettle must be washed. If the water is hard, it is unacceptable to leave it after boiling.
  • Once a day, and better, after each use, wipe dry.

And one more important rule. first water is poured, and then a “reagent” is laid. This is due to the fact that pure citric acid can be aggressive, for example, for plastic, so it is necessary to pour the immediately diluted solution.

This simple process is in more detail, how to remove the scale with citric acid and other means, you can watch on the video.

The effectiveness of citric acid when cleaning from scale

Detergents capable of riding kitchen utensils from scale, in stores enough is sold. But there is no guarantee that they will not harm the body. After their use, the dishes have to be thoroughly washed with running water, boil for a long time. Removing scale with citric acid is safe for health. The substance does not damage dishes, acts effectively.

A plaque, periodically appearing on the bowl, is a deposition of salts. They are destroyed under the influence of acids. Lemonk is the best tool in this struggle. Get rid of salt and lime deposits regularly. The procedure is low.cost in terms of means and time. Old deposits are removed longer. The method is simple:

  • Pour 40 gram packaging into a kettle;
  • boil for 10-20 minutes;
  • leave the liquid for an hour, with strong contamination. at night;
  • Rinse with clean water.
clean, kettle, citric, acid, much instructions for using citric acid to clean the kettle from the inside

Washed an enameled, electric kettle from scale with citric acid in two ways.



  • We remove a fresh plaque. We process the inside of the electric kettle with a sponge, paying attention to the heating element, wash off with water.
  • Fill the processed container with liquid, fall asleep one or two bags (depending on the thickness of the plaque).
  • Boil for three minutes. When you turn off the device automatically, we repeat the boiling procedure.
  • After three hours we drain the water, carefully remove the softened sediment with a soft sponge from the walls and the heating element. If the result does not satisfy, we do the manipulation again.
  • Rinse the remains thoroughly. Pour clean water, boil again.

With old persistent deposits, cleaning is carried out in three stages using citric acid, vinegar, soda. The option is suitable for metal teapots, glass or plastic may deteriorate.

  • Add 50 grams of soda to a container with water, boil for half an hour.
  • Pour clean water, pour two bags of citric acid, bring to a boil, drain.
  • Add half a glass of vinegar to two liters of water, boil for twenty minutes, drain. Rinse. The smell of vinegar will disappear in a day.

Without boiling

Between base cleaning (required monthly, if there is a lot of lime in the water), you can carry out easy processing:

  • Pour the bag of citric acid into warm water.
  • Pour the resulting solution into the kettle, leave for several hours.
  • Remove dirty water, rinse the container.
  • You can boil water, drink tea.

Spots and other pollution appear outside. They are easily cleared by citric acid, soda. Both funds are mixed in equal proportions. Fresh spots will help remove a piece of lemon. Cut the fruit, a slice treat the contaminated area.

clean, kettle, citric, acid, much

If the dishes are hopelessly damaged by a scope, make a solution of soda and lemon in hot water, immerse the processed object into the container. After an hour, pollution will move and easily remove with a soft cloth.

Soda successfully fights rust, just rub the surface or internal walls of the device using a sponge. The old rust can be removed using gruel of two components: soda and lemon. Sometimes mold appears on teapots for brewing tea. Rinse the container well enough, using any of the above funds, wipe the dry towers dry. Dishes are safe for use.

Other cleaning methods

Although citric okipi in an electric kettle is most effective, other methods of cleaning dishes are also known to the people. However, they are not so popular.

The use of soda

In a 2/3 container, add 1-2 tablespoons of soda. Let the solution brew for an hour, and then boil. After that, rinse and boil simple water.

Drill soda enhances the effect of citric acid without boiling, so the method is suitable for all types of teapots and electrical appliances.

Important! This method is not suitable for plastic products, since microcracks may appear after soda.

Using vinegar

Vinegar can only be used for ordinary teapots, for electrical appliances it will not work. It is necessary to dissolve vinegar in water in proportion 1 to 10. Boil this solution, and then let stand for about half an hour. After that, also rinse the device and boil ordinary water in it.

It is necessary to mix vinegar with water in a proportion of 1:10 and bring the solution to a boil.

The use of soda

The soda has a greater concentration of orthophosphoric acid, which, like lemon, can be used to dissolve a plaque. To do this, fill the container with a drink, leave for 3-4 hours, and then rinse. It is better to use, of course, a colorless drink.

Coca-Cola contains a lot of orthophosphoric acid, which, as well as lemon, is considered a rather weak.

Cleaning potato or apple peel

Since fruit acids are also found in other vegetables and fruits, they can also be used. Typically, take a potato or apple peel for this. A few pieces should be put in a kettle, pour water on 2/3 and boil. Then clean the usual way. However, this method is less effective, since the peel of fruit acids is not contained as much as in lemon.

If there are very few scale, you can use apple cleaning.


Citric acid from scale in a regular and electric kettle can also be used for prevention. Then thorough cleaning will be required less often. For prevention, the following methods can be recommended:

  • First of all, use filters to clean water. They will remove unnecessary compounds from it in advance.
  • Boil lemon water once. It is prepared at the rate of 1 tablespoon of citric acid per 1 liter of water. Such a ritual can be done once a week in the evening.
  • Wipe the device once a week with a slice of lemon, and then leave for 15-20 minutes. Then the unit can simply rinse with cold water. You can also clean glass dishes.
  • Wipe the inner walls daily with a simple damp sponge. You can do this in the evening. very convenient.

If you care for the device correctly, then its cleaning will not take much time. And it will last a long time and will delight the owners with delicious and pure tea.
