Copper

Copper objects and fixtures are often plated only with a very thin layer of copper and are often lacquered so they maintain a shine. As a result, you'll want to use the gentlest cleaning method possible so you don't rub through the plating or peel away the lacquer. Go over the lacquered copper with a cloth or sponge dampened in a solution of mild detergent and warm water, then rinse and buff dry with a clean cloth.
