How to clean a kettle with citric acid from scale

Impurities of harmful metals are even in water that has passed the stage of filtration. Substances during boiling deposited on the walls of pots, electric and ordinary kettles. A layer of scale forms, which not only increases the heating time of the device, but also causes a strange taste. Reddish plaque dissolve "Coca-Cola", acetic essence, potato or apple peel. But citric acid is considered the most effective and benign remedy.

Why does it work

Scale on the walls of the electric kettle appears due to an excess of magnesium and calcium salts, as well as iron impurities. Small particles of the substance settle on the inside of the device, gradually forming a thick layer of whitish or reddish plaque. In some cases, it is removed mechanically, but if the kettle is made of plastic or glass, cracks and chips may remain,which will reduce the life of the unit.

Citric acid works softer than popular storehouses, soda and vinegar essence. Dietary supplement enters into chemical reactions with the bloom. It dissolves metals and salt deposits. And also protects iron kettles from corrosion, which appears due to scale. Removes crayons brownish points and stains, stops the destruction of the material.

The tool does not leave scratches on plastic and glass surfaces, unlike soda. Water after using citric acid has a pleasant smell and aroma. And if the particles of the food additive fall into the tea, then nothing terrible will happen, because the component is not dangerous for the stomach and intestines.

Gentle method

A fresh layer of scale from glass and enamelled surfaces is removed with a small amount of citric acid. In a teapot filled with two thirds with water, pour 20–35 g of powder. The solution is stirred with a wooden spoon to dissolve all the crystals. Bring to a boil and leave on the stove for 5 minutes if the layer of potassium or magnesium salts is not too thick.Otherwise, you need to increase the interval to 10-15 minutes.

Electric kettles are equipped with an automatic shutdown system. In order for the water to continue boiling and after heating to 100 degrees, you need to open the lid of the unit before use. It is better to install a working appliance with the hood turned on so that the steam does not damage the ceilings and walls of the kitchen.

Lemon solution is advised not to pour into the sink, but into the pan. The billet can be reused to clean the outside of the kettle. Water with acid washes off both dirt, and traces of scale, and greasy stains.

Citric acid is a gentle remedy, but it has one drawback. In order for the additive to start interacting with salts and heavy metals, it needs at least 3-4 hours. Experienced housewives prefer to clean the kettle at night. When all family members fall asleep, they boil water with citric acid and leave it in the device until the morning.

Upon waking, they turn on the unit repeatedly, without replacing the solution. This is necessary to scale became soft and pliable. Most of the plaque will separate itself from the walls of the electrical device. The remaining pieces are washed off with a sponge.If the kettle is glass or enameled, it is better to take a soft cloth. It will not leave scratches on the fragile surface.

The rag is impregnated with detergent or soap composition. Carefully remove the scum with a sponge. And then several times pour distilled water into the device and bring it to a boil. Why do you need to take bottled liquid? It has a minimum of impurities. But in the version from the tap a lot of harmful substances that will re-settle on a clean kettle.

Glass kettles are updated and other, more gentle method. Solvent scale is prepared from warm water and 30–40 g of lemon powder. The components are stirred in a saucepan or jug, and then poured into an electrical appliance. Acid will take 4-5 hours to deal with the bloom. It remains only to rinse the container. And everything, it is possible to use kitchen utensils to destination.

If there are a lot of hardened salts on the walls, the basis for the cleaning solution is heated to the boiling point. Pour 2 small sachets of acid into a hot liquid and mix everything thoroughly. Capacity tightly closed with a lid and wait until the water has cooled completely. The procedure is repeated from 1 to 3 times.Lemon powder does not damage the walls of the kettle.

Sometimes the raid eats into the material so much that it cannot be softened the first time. Then resort to a variant with soda. After treatment with lemon solution, a slurry of baking powder and water is applied to the walls. Tinder kettle sponge or cloth to dissolve the plaque. And repeat the experiment with citric acid.

Aggressive way

The old erupted scale dissolved with a mixture of vinegar, soda and citric acid. The composition is effective, but not suitable for working with glass and thin plastic. In this way, metal teapots that are boiled on the stove are more often cleaned. Electrical options may break. The solution also removes scale from enamelled surfaces. But in this case it is impossible to combine vinegar-lemon solution with rigid brushes and sponges.

The first stage is the softening of soda. In the device, filled with distilled water, pour 30-50 g of the food additive. The solution should boil from 20 minutes to half an hour. Hot liquid is poured into the sink. In a new batch of water, add 2-3 small sachets of citric acid. Bring to 95-100 degrees, immediately drained.

The last step is the acetic solution. 1.5-2 liters of half a cup of supplements. Boil as much as soda. Pour, rinse twice with clean water. A vinegar smell may remain, but it will disappear on the second or third day. It can be removed by adding some citric acid to the rinse.

To update the kettle with stainless steel helps vinegar solution. The variant is intended for utensils that are heated on the stove, but not for electrical specimens. The container is filled with water half, add 150 ml of vinegar. Insist 20 minutes to add a chemical reaction with salt deposits. Then 40–60 g of citric acid is poured into the solution. Stir, bring to a boil and immediately turn off the stove. Water with additives is not poured, and cooled for 20-25 minutes. Then gently shake so that the particles of solidified salts are separated from the surface of the kettle.

The softened plaque that remains on the enamel or stainless steel is treated with a soft sponge. On the inner and outer walls of the kettle put a little detergent for dishes. Cleaning is carried out in rubber gloves so that the vinegar-lemon solution does not damage the skin.It remains to rinse utensils and wash the remnants of plaque and aggressive substances.

Preventive measures

20–25 g of food supplement is poured into the water. Stir to crystallize dissolved, and not settled on the bottom. The liquid is heated to 90–95 degrees. Insist all night, and in the morning rinse the kettle with warm water. You can simply fill the device with a solution of citric acid and insist half an hour without boiling. But this method works only with fresh scum.

A raid of magnesium and potassium salts appears on the walls of kettles due to poor water or bad filters. Soft and gentle cleansing of kitchen utensils from solidified precipitation is carried out with citric acid. Food supplement is also used for the prevention of scale and corrosion.
