Dirt, grime, fingerprints, and slight traces of oxidation can be removed using a solution made up of 50% lacquer thinners and 50% water. Be sure to clean the copper sheet metal panels only with the direction of the grain, never against the grain. You will need to use a lint-free cloth for the cleaning, then rinse the panel using clean water, and wipe with a dry lint-free cloth to dry.
Copper sheet metal, or as it is sometimes referred to as “Electrolytic Tough Pitch Copper,” is a copper alloy composed of 99.6% copper and 0.4% oxygen. It has a reddish appearance from the high copper content. While copper metal is not very popular in the architectural community, save for occasional kitchen range hoods and exterior home decorative trim, it is commonly used for industrial applications in the form of round, square and flat bars.
