Glass is considered universal material because it withstands aggressive substances. It is not for nothing that laboratory glassware is made from it. Nevertheless, it is worth remembering that glass surfaces do not like abrasives. If you use baking soda for cleaning, do not rub it against the walls of the kettle, but only boil the soda solution.

Enamel can be stained in the presence of bright dyes, regardless of their composition. In addition, it does not tolerate sudden changes in temperature. Therefore, first you need to fill cold water, bring it to a boil, and then rinse either hot water or let the kettle cool down to room temperature.

Stainless steel, like glass, can withstand almost any experiment with cleaning products. Dislikes abrasives. Small scratches spoil the beautiful gloss, although they do not affect the functionality.

For this reason, it is better to alternate acidic and soda procedures, and also not to start the situation until you need to resort to emergency cleaning methods.

And if thin layer scale does not cause significant harm, then over time the device will, at best, stop working effectively, and at worst, it will break down completely. Does not bring joy and scale with rust inside ordinary teapots - metal or enameled.

Is it possible to get rid of this problem, and how to carry out a global cleaning of the kettle at home?

  • Vinegar(method for a metal teapot). fast and high-quality cleaning dishes without harm to health and the use of "chemistry". We dilute food vinegar with water (100ml / 1l), pour the solution into a bowl, put it on fire (small) and wait for it to boil. As soon as the kettle boils, you should lift the lid and check how the scale is peeling off the walls of the kettle. If the detachment is incomplete, leave the kettle on the fire for another 15 minutes. Then we wash the kettle well, removing all residues of vinegar and deposits. It is advisable to ventilate the room after cleaning.
  • Lemon acid (method for a plastic electric kettle and ordinary kettles). It is not recommended to use vinegar for an electric kettle (otherwise the kettle can simply be thrown away), but citric acid - great helper for cleaning. Dilute 1-2 sachets of acid (1-2 tsp / l) in a liter of water, pour the solution into a kettle and boil. The plastic of the kettle will “renew itself”, and the plaque will disappear without a trace, easily exfoliating after the acid. All that remains is to rinse the kettle and boil the water “idle” once. Note: it is best not to bring the kettle to the point where it needs a tough cleaning, as citric acid is also a fairly serious remedy for household appliances. Perfect option- regular cleaning of the kettle with citric acid without boiling. Just dilute the acid in water, pour it into the kettle and leave it for a few hours.

  • Soda! Do you like Fanta, Cola or Sprite? You will be interested to know that these drinks (taking into account their "fusion" composition) ideally clean rust and scale from dishes, and even car carburetors from burning. How? After the "magic bubbles" disappear (there should be no gases - first defend the soda in open form), just pour the soda into the kettle (up to the middle of the kettle) and bring to a boil. After - wash the kettle. The method is not suitable for an electric kettle. It is recommended to use Sprite, since Cola with Fanta can leave a shade on the dishes.

  • Impact method (not for electric kettles). Suitable for the most running state of the kettle. Pour water into the kettle, add a tablespoon of baking soda (table), boil the solution, drain the water. Next, pour water again, but with citric acid (1 tablespoon per kettle). Boil for about half an hour on low heat. Drain again, add fresh water, pour vinegar (1/2 cup), boil, again, 30 minutes. Even if the scale itself does not come off after such a shock cleaning, it will definitely become loose, and it will be possible to remove it with a simple sponge. Hard brushes and metal sponges are not recommended for all types of kettles.

  • Soda(for metal and enamel teapots). We fill the kettle with water, pour 1 tbsp of soda into the water, bring to a boil, then leave it on low heat for 30 minutes. Next, we wash the kettle, fill it with water again and boil “idle” to remove the remnants of soda.

  • Brine. Yes, yes, you can clean the kettle with the usual brine from under tomatoes or cucumbers. The citric acid in the brine will also help remove scale. The scheme is the same: pour the brine, boil the kettle, cool, wash. Cucumber pickle perfectly removes rust from iron salts in the kettle.
  • cleaning."Grandma's" method of descaling. Suitable for light scale deposits in enamelled and metal teapots. We wash the potato peels well, remove the sand from them, put them in a kettle, fill with water and boil. After boiling, we leave the cleaning in the dishes for an hour or two, and then carefully wash the kettle. And apple or pear peels will help to cope with a slight coating of white “salt” scale.

Regardless of the cleaning method, do not forget to thoroughly wash the kettle after the procedure and boil the water empty (1-2 times) so that the remnants of the product do not get into your tea. If the residue after cleaning apple peels will not cause harm to health, then the remnants of vinegar or soda can cause serious poisoning. Be careful!

In any water heater, from time to time we find a treasure trove of minerals, namely deposits of magnesium and calcium salts from hard water. And if we always try to prevent the formation of scale in the dishwasher and washing machine, then what can we say about the kettle, where it not only impairs its performance and leads to breakdowns, but also harms the health of the household.
