Copper Cleaning Instructions
Generally, the copper tarnishes and turns dark and dull. This tarnishing occurs when the copper reacts with the air and a patina develops. The color of the patina will vary with the copper and what it is exposed to. Inside the house, copper will gradually get an antique penny brown color.
