It is well known that scum in a kettle issalt deposits, namely calcium and magnesium salts of carbonic acid, sulfuric or methacilicic. All of these compounds react with acids, forming soluble substances, passing into the water. This is their property and is the basis of descaling. However, different compounds interact with acids in different ways: carbonates are most easily removed, worse - silicates and sulfates. In order to remove scale in a kettle, it is not necessary to be a professional chemist and have at your disposal a whole arsenal of chemicals. Often enough to use those simple ingredients that are in any kitchen. Accumulated over the years and passed down from generation to generation, popular wisdom knows how to remove scale from improvised means. In addition, there are a lot of industrial products for the same purpose, but many people do not want to use additional "chemistry", given that we already have to deal with a lot of unhealthy chemicals every day. Before you remove scale in the kettle, pay attention to the material from which it is made. So, many electric kettles are made of plastic, and it is not always resistant to aggressive chemicals, the same applies to the spiral, which can begin to rust.
But folk remedies for descaling have virtually no side effects. We list them:
The most ancient method of descaling was mechanical: the coating was cleaned with sand or other abrasives. However, it is quite long and laborious, and therefore it does not suit us. - Soda in a concentration of 10 grams per liter, boiled for 10-15 minutes, also saves from scale, but only in the easiest cases.
- Sufficiently removes scale in the kettleboiling vinegar solution: 10-20 ml per 1 liter of water. The disadvantage of this method is the pungent smell of vinegar, which can cause headaches and various allergic reactions.
- A more gentle version of the previous method is citric acid. It should be boiled in a kettle (1 sachet per 1 liter of water) for 5-10 minutes depending on the degree of contamination.
- Ascorbic acid (vitamin C) can also be used to clean dishes from scale. However, this tool is quite expensive.
- For lovers of natural products you cansuggest boiling water with pieces of chopped fresh lemon (the same citric acid works), apple (malic acid) or raw potatoes (citric and ascorbic acid). All of these agents are also effective for small soiling.
Strong enough, though not cheap, meansfrom scale are carbonated drinks. You can also use highly carbonated water, but cola, sprite and others are much more effective. They act at the expense of the acids in their composition (citric, orthophosphoric and others), as well as due to carbon dioxide, which is also capable of destroying salt deposits. Using drinks to clean scale, be careful: they contain various dyes that can permanently stain the plastic of the kettle. Drinks are most effective if you first boil them in a kettle, then leave to stand for several hours, then drain and wash them thoroughly.
Накипь в чайнике образуется даже при use of filtered water, since no filter will remove water from the salt by 100%: this can be achieved only when using reverse osmosis systems, however, according to some scientists, it is undesirable to eat such water. And because the means for removing scale should be noted on each hostess.
