• To remove grease stains small size Dip a lemon wedge in fine salt and rub the problem area thoroughly. This method is not suitable for a metal device, since darkening may occur on its wall.
• To completely clean a metal kettle, immerse it completely in a large container, which needs to be filled with a solution of lemon powder. The hotter the water and the greater the concentration of the substance, the faster the cleaning process will be completed.

You will have to tinker with a metal kettle. Solutions to rust problems using citric acid:

• If the contamination is light, then prepare a solution at the rate of 1 liter of water per 1 tbsp. spoon of citric acid. Apply the solution to a sponge and wipe the problem areas with it until the rust is completely removed.
• Works great against rust regular juice lemon Cut the fruit, wipe the surface of the device with it (several minutes) and leave for a while. Wash the cleaned kettle using detergent and rinse warm water.

Methods for descaling are divided into mechanical and chemical. Because the mechanical cleaning can cause irreparable damage to the surface of the kettle, a more gentle method is chemical method.

Over time, mechanical cleaning leads to the appearance of small scratches on the inner surface of the dishes and becomes a favorable environment for the growth of bacteria.

Citric acid, as a cleaning agent, helps cookware last longer. The cleaning procedure does not require special preparation. To do this, you need to pour the water out of the kettle, and electric models will need to be disconnected from the network.

Using purified water will protect dishes from the rapid formation of plaque.

How to quickly remove scale from a kettle

To clean the kettle with citric acid quickly and effectively, you should use the following algorithm:

• Determine how much substance is needed to remove scale. The thicker the plaque, the more acid is needed. Required proportion: 2 teaspoons of citric acid per 1 liter of water;
• Pour clean water into the kettle, filling 2/3 of its volume;
• Add the powder to the water and stir until it is completely dissolved;
• If the scale has recently formed and its layer is quite thin, then there is no need to boil it; just leave the acid solution in the kettle for 2-3 hours. Then you need to thoroughly wash the container, freeing it from any flakes and grains that have formed. If the plaque is more old, you need to boil an aqueous solution of lemon juice in a kettle for a quarter of an hour. After this, let it cool and wash the dishes with clean water. If necessary, the procedure can be repeated more than once.

Caution: when citric acid is poured into boiling water, rapid formation of bubbles occurs; burns should be avoided.

Types of teapots

The different materials from which teapots are made require different care. Selected species, such as plastic, require special handling. Citric acid has the most gentle effect on dishes, so it can be used to clean almost all types of dishes. Soda or acetic acid have a more aggressive effect; their use requires a careful approach.

Metal

The cleaning method using citric acid is suitable for a moderate layer of scale in a stainless kettle. For aluminum cookware This method is not suitable, since when heated, aluminum reacts and slightly dissolves.

1. Bring water to a boil in a stainless steel kettle.
2. Dip a slice of lemon into it or pour in a little powder, leaving the resulting acidic solution to cool.
3. Wipe it with a damp sponge and drain the first water after boiling.

Plastic

Since acetic acid is not suitable for electric kettles made of plastic, using citric acid is an excellent way out.

You can get rid of thin deposits even without boiling.

1. Fall asleep in hot water 1-2 teaspoons citric acid powder.
2. Cool the solution.
3. Drain the water.

After this procedure, the plaque will disappear, you will only need to boil the first batch of water “idle”.

Enameled

Cleaning enamel cookware requires approximately the same algorithm as metal cookware. Just keep in mind that in order to avoid cracking of the enamel coating, sudden temperature changes should not be allowed.

Do not rinse the kettle with ice water immediately after using boiling water with citric acid. Gradual cooling will protect the dishes from damage and keep the surface intact.

Glass

Both dry powder and a couple of lemon drops added to water are suitable for cleaning glassware.

An alternative way to clean glassware is to use lemon essential oil.

1. Add 20 drops of oil to two glasses of clean water.
2. The resulting composition is applied to the inner surface of the kettle.
3. After a few minutes, the sediment will soften and can be removed with a soft brush or sponge.

Electric

Cleaning an electric kettle with citric acid involves using powder, but you can also use slices of fresh lemon.

1. Add them to boiling water and open the lid of the electrical appliance, without letting it turn off for several minutes.
2. Allow the water to cool and the container will become clean and fresh.
3. Unpleasant odors and accumulated deposits can be washed off with running water.

Another way to cleanse is to:

1. Leave the aqueous solution of citric acid in the kettle overnight.
2. In the morning, drain the water with the separated sediment.

This method is suitable for light sediment and does not harm the electrical appliance.

Whitening and descaling

Lemongrass is often used for cleaning and whitening various surfaces, household appliances and linen.

The rate at which deposits appear depends on the salt content in tap water: the more there are, the faster plaque forms.

Benefits of use

The use of citric acid to eliminate accumulated insoluble salts has many advantages over other cleaning methods.

The main advantages of this method:

• Low cost and can be purchased at any grocery store;
• High efficiency - 100 grams can dissolve up to 80 grams of hardened deposits;
• Ease of use, since everyone can handle the cleansing process;
• Safety for human health and the environment: the formation of calcium citrate when dissolving salts does not pose any threat.

In terms of its cleansing properties, citric acid is a complete and effective analogue of specialized cleaning products, since the chemicals of the latter negatively affect human health.

Preventing scale and caring for the kettle

To prevent the formation of sediment in dishes, you need to take several simple preventive measures:

• Use filtered or settled water with a reduced concentration of salts;
• Pour the liquid remaining after boiling into another container;
• In enamel dishes, boil only once. Repeated boiling will speed up the process of plaque formation;
• Carry out preventive cleaning with citric acid 1-2 times a month;
• Give preference to electric kettles with a closed spiral;
• Rinse the vessel before boiling water.

Properties of citric acid

Citric acid is a crystalline powder white, which is highly soluble in water. In living nature, acid is found in a large number of fruits and vegetables, has low level toxicity.

Dosed use of the powder does not cause harm to the human body And environment. The substance itself is widely known for its characteristics due to its biochemical formula.

Citric acid is used in a variety of areas:

• food industry;
• medicine;
• cosmetics production;
• oil production;
• construction;
• at home.

Its active use as a household cleaning agent is due to its chemical composition.

Citric acid has a more gentle effect than acetic acid.

Is it possible to wash a kettle with citric acid?

Regular use of lemon juice to wash the kettle can significantly extend its service life and gradually free it from minor scale deposits on the internal surfaces.

When using citric acid, precautions must be taken. Despite the fact that this substance is widely found in nature, contact of the concentrate with human mucous membranes and skin leads to burns. Dry powder can be irritating to the respiratory tract, so inhaling it when washing dishes should be avoided.

Important: regular cleaning is less labor-intensive than getting rid of a thick layer of compressed deposits.

You can remove scale from dishes using substances containing acids. It is recommended to clean dishes in a timely manner while the plaque layer is minimal. Knowing the secrets of cleanliness will help lead household with a minimum of effort.

Despite modern systems water purification, it does not always remain crystal clear. The kettle that boils this water eventually gets an unpleasant deposit on the walls and bottom - scale. It is not always possible to remove it with dishwashing detergents, especially if the kettle is electric. Its body cannot be completely immersed in water. But there is universal method, how to clean any type of kettle - citric acid.

Citric acid and cleaning
Using citric acid, you can clean an electric kettle, both inside and outside, regardless of the type of kettle itself. This could be a kettle on a stand or a thermopot with a cleaning mode. You are required to:

• pour cold water into the kettle;
  
• pour a packet of citric acid (10-12 grams) into it;
  
• plug in the kettle;
  
• after boiling, open the lid and let the water boil for a few more minutes;
  
• pour the water into the pan, if necessary, rub the kettle with a soft sponge to remove plaque;
  
• You can rub the outside of the kettle with boiled water and citric acid so that there are no streaks;
  
• Pour clean water into the kettle and boil;
  
• drain all the water again;
  
• fill the kettle again, boil and you can enjoy clean water without residue.
  

If you have a thermopot with a cleaning mode in your kitchen, then simply pour in water, add citric acid and set the “cleaning” mode. After boiling, drain the water, wipe the bowl with a soft sponge, pour in water again and boil. The procedure can be repeated if all the scale is not removed the first time. It is not recommended to rub plastic teapots with a hard sponge to avoid scratching the coating. In the same way they clean and enamel teapots for the stove. To completely remove the smell of citric acid, you will have to drain and boil the water at least 2 times.

Citric acid and vinegar when cleaning the kettle
This cleaning method is only suitable for metal stovetop kettles. Fill half the water, pour in half a glass of 9% vinegar. Let the kettle sit for a while (10-15 minutes). Then add a tablespoon of citric acid and boil water with this mixture. After boiling, turn off the stove and let the kettle sit for 20 minutes. Drain all the water, wipe the inside of the kettle with a sponge detergent, rinse. It is advisable to use rubber gloves for the procedure; the mixture is very aggressive. Kettle to use in the usual way It is possible only after three boilings and then draining the water, so as not to get food poisoning or allergies.

Citric acid is food product, which effectively removes scale and is safe for humans in small quantities. The composition of scale is an alkali, which can only be softened and removed with acid. Special means anti-scale agents can be used to clean the inside of the kettle, but may be unsafe for health.
