How to Clean Copper with Commercial Copper Cleaner?
When buying a commercial cleaner, take care as these may be too harsh to be used on copper, and can scratch your copper rather than making it shine. It’s recommended to buy a cleaner that has been specifically made for use on copper.
Copper cleaners are ideal for highly tarnished pieces. Follow the instructions on the cleaner and rub the piece with a soft cloth until the copper gleams again.
