Some traces of improper use, such as making tea for too long, may cause the coating of the health pot to fall off. The purpose of the coating is to protect the metal surface from chemical attack of food or drink. If the coating falls off, the metal may react with food or drink to produce harmful substances.
In order to ensure personal health and safety, it is suggested to stop using the incubator and check whether there are other signs of improper use. If you need to continue to use the health pot, you can choose other brands or models to ensure safety and hygiene.
