To clean scum from the electric kettle, it is possible to use the easiest way. For this purpose it is necessary to use citric acid. For this purpose in teapot pour cold water. Now in it it is possible to pour out one bag of citric acid and to boil. After water has begun to boil, the teapot can be disconnected and given it will cool down. Having drained water, it is necessary to look whether there is in teapot scum. In case the scum remained, it is necessary to repeat this procedure. If it was succeeded to remove scum, then the teapot needs to be washed out carefully under flowing water. It is necessary to boil clear water in teapot and then again to rinse it under cold water. To get rid of scum, it is possible to use special powder, antiscale agent. Its chemical composition contains components which also promote destruction of scum.
If the scum has to be removed from normal teapot not electric, then for this purpose it is necessary to prepare normal baking soda. Filling in teapot water, it is necessary to add several teaspoons of soda and to boil it. Process of boiling has to be about half an hour then it is necessary to pour out water and to look whether there was still scum on teapot walls. If layer of scale big, then it is necessary to use not soda, and vinegar. It is poured in teapot 100-150 ml and also boiled within 30 minutes. After the scum is removed, it is necessary to wash teapot with clear water.
Besides teapot there is need to clean scum and from the home iron. If the iron possesses self-cleaning function, then, of course, it is necessary to use it. The iron in this case has the special button, having pressed which, process of cleaning of scum will be executed independently. For this purpose in special capacity water is filled in and maximum temperature is established. As soon as the iron is heated, it will automatically be switched-off. The procedure should be repeated, having waited the teapot will cool down so far. Now it is necessary to switch-off the iron and to carry it to the bathroom where press the button of cleaning of scum. If with steam-out all water did not come out, then the iron should be stirred up accurately, holding at the same time the cleaning of scum pressed the button. If similar function is not provided, then it is possible to use any store means for de-scaling. In deep form it is necessary to lay several rails (wooden) and to put on them the iron. Its sole should not concern bottom. In this form boiled water is filled in and means of de-scaling is filled. The height of water at the same time has to be 1-1.5 cm higher, than iron sole. It will protect electric parts of the iron from soaking. It is necessary to leave the iron in such state for 10 minutes. That water did not cool down and cleaning from scum was successful, the form with the iron can be put on weak fire.
