Because the tap water we use every day contains calcium ions, magnesium ions and a small amount of bicarbonate ions, the tap water will be deformed if it is boiled for a long time.
Magnesium carbonate will react with water and be heated continuously to produce more insoluble magnesium hydroxide, calcium carbonate and magnesium carbonate.
Quality is a substance with little solubility, which will form precipitation in water and scale over time.

1, descaling methods mainly include the following: vinegar descaling, and the main components of scale are carbonate such as calcium carbonate and acetic acid in vinegar.
It will react with calcium carbonate to produce water-soluble minerals and carbon dioxide gas. White vinegar is generally used, and it is better to put it in a pot.
Ten tenths of white vinegar, then add water to boil, and cleaning will remove scale.
2, baking soda in addition to scale, electric kettle to boil water, you can add a spoonful of baking soda, cook for a few minutes, you can also pour thick soup.
Baking soda water with a degree of 1% is about 500g, and the scale can be removed by shaking it gently.
3, boiled eggs In addition to descaling, you can cook the eggs several times with an electric kettle, or you can descale, slightly break two egg shells and put them in the bottle.
Add half a pot of water, stir with a blender, then boil it, leave it for about half an hour, pour out the eggshell and wash it twice with clear water.
Yes
4, potato skin descaling, you can put a lot of potato skin in it, add the right amount of water to boil, cook for about ten minutes to remove.
Scale removal by thermal expansion and cold contraction. Empty the water in the pot first, then put it on the fire until the pot doesn't steam. Take it out immediately and put it directly into the bowl.
In the container with cold water, it is recommended not to let water enter the spout. At this time, due to the sudden contraction of the bottom of the pot in cold water, thick scale
Will naturally break and fall off. But pay attention to safety when operating. If you are not careful, your kettle will burn out.
