2. Acidic substances. Acidic substances are the bane of scale. After boiling water, you can add a few slices of lemon or vinegar to the health pot and soak for an hour or two, and the scale can be easily removed. It is more suitable to use lemon than vinegar, because vinegar has a strong fragrance and is not easy to disperse for a long time. People who are not used to it will feel uncomfortable, and the taste left by lemon is relatively fresh.
3. Alkaline substances. Soak some potato skins, chips, etc. Put it in a health pot for a long time, it can quickly remove scale. Dry the cooked health pot naturally, and don't wipe it with water and cloth in the middle, which can also prevent the subsequent scale.
