How to remove scale from thermos?

Thermos will form scale after using it for a long time. If the harmful substances are not cleaned in time, it will endanger your health. The main components of scale are calcium carbonate and magnesium carbonate. You should clean the scale in the thermos on time. Many people do not know how to clean the scale in the thermos, and even replace the thermos. In fact, you don’t have to replace it directly. There are some methods to clean the scale. How to remove the scale in the thermos? Let's take a look.

1. Method 1

1. Buy a lemon, cut it into slices, put it in the kettle, boil some water and pour it in, cover it with a lid and let it soak in it. Pour it out after it cools down and the scale inside will fall off.

2. Boil some dried hawthorn in water. After it boils, pour it into the kettle, soak it for a day, pour it out, and the scale inside will fall off.

3. The most commonly used method is to pour some white vinegar into it, add some boiling water, and soak it. If there is a lot of scale, add more vinegar. Soak it for a while and then shake it. It will be clean soon. However, if you use vinegar, there will be an odor in the pot and you will have to wash it more times.

4. Rice (noodle) soup descaling method: Pour the leftover rice soup or noodle soup into a pot full of scale. The thicker the better. In order to make it ferment as soon as possible, put the kettle in a higher temperature in winter. After a few days of natural fermentation and sourness, the scale in the pot will slowly fall off. The longer it is left on, the better the descaling effect will be. The advantages of this method are that it is safe, labor-saving, and does not damage the kettle. This method is a little time-consuming.

1. Crush the eggs and put them in the thermos (add more egg shells for a better cleaning effect)

3. After shaking for a while, check if the scale inside is clean. If it is clean, pour out the egg shell in the thermos and rinse it with water.

3. Notes

The main components of scale are calcium carbonate and magnesium carbonate. If there is scale, remove it in time.
