I asked a friend to buy a Kobayashi pharmaceutical in Japan before, and bought it with other things and sent it back. It's really good. It's better than I usually use vinegar to clean the inner container of the electric kettle, and it won't have a big smell. This is mainly to put warm water in the electric kettle first, and then put this medicine in it. After you put it in, you can let it stand there for half a day, and then rinse it with clear water several times. It's very clean, almost as good as new.

If it is an electric kettle with a glass shell, the bottom can still be cleaned in the above way, or you can save a little, just pour some vinegar and let it stand for a while. But I suggest that the glass cover can be dipped in a toothpaste brush with a toothbrush. This is how I cleaned the health pot I bought before. In fact, I think toothpaste is really a universal cleaner. No matter what dirty things are at home, I will first think of cleaning them with toothpaste.
