Cleaning Copper
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.
