You can also use lemon slices to wipe the oxidized part until it is clean. Be careful not to touch water when deoxidizing. Remove copper rust If the copper pot produces green copper rust, it means that it is exposed to corrosive substances such as acid, alkali and salt, and can be wiped repeatedly with some lemon juice and salt. You can also wipe the cloth with kerosene, and then wipe it with toothpaste powder. After use, it should be dried and stored in a dry place. Usage change: It is normal for the copper pot to turn black after use. When boiling water in a copper pot, a dark brown oxide film will naturally form on the inner wall of the copper pot over time, which will not change the boiling effect or bring negative effects, so there is no need to wash and clean it. Only when the copper ware is combined with acidic substances will it produce copper rust. After normal use for a period of time, the surface of the copper pot will have a natural patina, which will be more moist and attractive with more use.
