What are the methods for removing scale

Nowadays, drinking water is becoming less and less secure. Once the kettle and cups at home are used for a long time, some scale that is difficult to clean will appear. Such scale is very troublesome, because if it is not cleaned properly, sometimes even your kettle and cup will be scrapped. So, what methods are used to clean water cups and kettles to remove such stubborn scale?

1

Use vinegar to remove scale: As we all know, the main component of scale is carbonate such as calcium carbonate. The acetic acid in vinegar will react with it to produce water-soluble minerals and carbon dioxide gas. White vinegar can be bought in general supermarkets. Put 10% of white vinegar into the kettle scale, then fill it with water, boil it and let it sit for about an hour, then brush it. Aged vinegar can also be used, but the effect of aged vinegar is not as good as white vinegar.

2

Descaling an electric kettle by boiling sweet potatoes: Put more than half of the sweet potatoes in the kettle, fill it with water, and cook the potatoes. Next time you boil water, there will be no scale accumulation. But be careful not to scrub the inner wall of the kettle after boiling sweet potatoes, otherwise the descaling effect will be lost. For old kettles that are full of scale, after boiling them once or twice using the above method, not only will the original scale gradually fall off, but it will also prevent scale from accumulating again.

3

Use baking soda to remove scale: Generally, the heating plate of electric kettles is made of aluminum. When boiling water in the electric kettle, scale is easily formed. Generally, we can put 1 teaspoon of baking soda and boil it for a few minutes to remove the scale. Alternatively, you can pour in about 500 grams of 1% baking soda water, shake it gently, and the scale can be removed.

4

Boil eggs to remove scale: Generally, electric kettles will accumulate hard and difficult-to-remove scale after being used for a long time. If you use it to boil eggs twice, you will get the desired effect. Crush two egg shells slightly, put them in a bottle, then fill in half a pot of water, stir with a blender or spoon, then boil it, let it sit for about half an hour, pour out the eggshells, and rinse it twice with clean water.

In fact, removing scale is not that difficult. As long as we know the composition of scale and use some chemical principles, we can easily remove the scale. Things like this tell us a truth: as long as you are willing to think, no matter how difficult the problem is, it can be solved.
