Exposure to air and water causes oxidation to take place which changes the color of copper. You can clean copper to a beautiful shine without harsh cleaners or strong fumes.
Things You’ll Need:
- Possibly Salt
- Possibly Flour
You can typically remove copper oxidation by simply rubbing the copper with a cotton rag soaked in vinegar.
If you prefer to use citrus juice, this will also remove the oxidation from copper.
For tougher cleaning jobs that require scrubbing, mix equal parts of salt and flour together. Add enough vinegar to the mixture to make a paste. The salt provides abrasiveness. The flour helps to form the paste.
