There are many ways to remove scale on the thermos. Some people say using vinegar or toothpaste.

Here are the specific methods:

It can be soaked in a proper amount of vinegar and water to make it slowly dissolve, because the scale is alkaline, which will drive away the annoying scale. Every family uses a kettle, and every family cares about limescale. For this reason, several simple and easy methods to remove scale are recommended, and you might as well try.

1. Descaling by boiling sweet potato in a kettle: Put more than half of the sweet potato in the new kettle, fill it with water, cook the sweet potato, and then boil the water, so that the scale will not accumulate. But be careful not to scrub the inner wall of the kettle after boiled yam, otherwise the descaling effect will be lost. For old kettles that are already full of limescale, after using the above method once or twice, not only the original limescale will gradually fall off, but also can play a role in preventing the accumulation of limescale again.

2. Descale with baking soda: When boiling water with an aluminum kettle with scale, put 1 teaspoon of baking soda and boil for a few minutes to remove the scale.

3. Removal of scale from boiled eggs: the pot of boiling water will hardly remove the scale after a long time. If you use it to boil eggs twice, you will get the desired effect.

4. Descaling from potato peel: A thin layer of limescale will form after using the aluminum pot or aluminum pot for a period of time. Put the potato skins inside, add appropriate amount of water, boil, and cook for about 10 minutes to remove.

5. Thermal expansion and contraction to remove scale: Put the empty kettle on the stove to dry the water in the scale. When the bottom of the kettle is cracked or the bottom of the kettle is "bang", remove the kettle and quickly fill it with cold water , Or wrap the handle and spout with a rag, hold it with both hands, and quickly sit the boiled kettle in cold water (do not let water pour into the kettle). Repeat 2 to 3 times, the scale on the bottom of the pot will fall off due to thermal expansion and contraction.

6. Removal of scale with vinegar: If the kettle has scale, put a few even vinegar into the water and boil it for one or two hours to remove the scale. If the main ingredient in the scale is calcium sulfate, pour the soda ash solution into a kettle and boil it to remove the scale.

7. Mask to prevent scale accumulation: Put a clean mask in the kettle. When boiling water, the scale will be absorbed by the mask.

8. Magnetization: Put a magnet in the pot, not only does not accumulate, the boiling water is magnetized, but also has the effect of preventing constipation and pharyngitis.
