1, lemon peel: squeeze the lemon peel dry and soak it in a small bowl of warm water for 4 ~ 5 hours to remove tea stains and water stains from the health pot. If it is a health pot, you can wrap the lemon slices in cloth and put them in the upper part of the health pot, which is filled with water. Boil the lemon in the form of coffee and let it drip into the pot below until the yellow turbid water drops flow out of the health pot.

2. Salt: Apply edible salt to the inside of the health pot, especially where there is tea dirt, then scrub the teacup with a toothbrush or hands, and finally rinse it with clear water. The main component of salt is NaCl, which contains impurities such as magnesium chloride and KCl. The hydrolysis of Mg+ makes the salt acidic, and acidic substances can remove theophylline and other substances from tea scale.

3, vinegar descaling: This method is the simplest and most practical method. As we all know, the main component of scale is carbonate such as calcium carbonate, and acetic acid in vinegar will react with it to generate water-soluble substances, minerals and carbon dioxide gas. You can buy white vinegar in general supermarkets, put it in a health pot with the ratio of 10%, then fill it with water, boil it for about an hour, and then scrub it. Old vinegar will do.

4. Boil yam in a household electric kettle for descaling: put yam above the semi-health pot, fill it with water, cook the yam, and then boil the water later, so that scale will not accumulate. However, it should be noted that do not scrub the inner wall of the kettle after cooking the sweet potato, otherwise it will lose the descaling effect. For an old health pot that has been covered with scale, not only will the original scale gradually fall off, but it can also prevent the scale from accumulating again after being boiled once or twice by the above method.

5, baking soda descaling: the heating plates of general household health pots are all made of aluminum. When boiling water in a health pot, it is easy to form scale. Generally, we can put 1 teaspoon baking soda and boil it for a few minutes, and the scale will be removed. Or you can pour about 500g of baking soda water with the concentration of 1% and gently shake it to remove the scale.

6, boil eggs to remove scale: General household health pot, used for a long time, scale is difficult to remove, if you cook eggs twice with it, you will get the ideal effect, break two egg shells slightly, put them in a bottle, then put half a pot of water, stir with a blender or spoon, then boil, leave them for about half an hour, pour out the eggshells and rinse them twice with clear water.
