The principle of acetic acid to remove scale

In order to remove scale, many people use many methods, but before using these methods, you should also pay attention to whether this method is safe and effective. Now many people use acetic acid to remove scale, so you should pay attention to and understand whether acetic acid technology has such an effect on scale removal, and what is the principle of this scale removal?

Acetic acid, also known as acetic acid (36%--38%) and glacial acetic acid (98%), has the chemical formula CH3COOH. It is an organic monobasic acid and the main component of edible vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic solid with a freezing point of 16.6°C (62°F). It solidifies into colorless crystals. Its aqueous solution is weakly acidic and highly corrosive, and its vapor is irritating to the eyes and nose.

The acetic acid content in vinegar is extremely low, and its ability to remove scale is poor. In addition, when you boil vinegar in water, its concentration is even lower. After boiling, some acetic acid evaporates, and its ability to remove scale will be greatly reduced. It is recommended to use a special stainless steel descaling agent.

You can also try the following method:

① Descaling the kettle by boiling sweet potatoes: Put more than half a kettle full of sweet potatoes, fill it with water, and cook the sweet 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.

② Use baking soda to remove scale. When boiling water in an aluminum kettle with scale, add 1 teaspoon of baking soda and boil it for a few minutes to remove the scale.

③Boil eggs to remove scale. The scale on the kettle that boils water will become hard and difficult to remove after being used for a long time. If you use it to boil eggs twice, you will get the desired effect.

The above are some methods and techniques for removing scale with acetic acid. After mastering these methods and recognizing and understanding the problem of scale, I believe everyone should now know which method to use to help remove the scale problem more quickly if faced with scale in life.
