Answer:

Cleaning Badly Tarnished Copper
You will want to clean it with an Acid. The strongest cleaner for Copper is Muriatic Acid. You need a reducing agent here, in other words you want to reduce the copper from its oxidized state which is the dark tarnish. I would take and mix about 1/4 cup of Muriatic Acid to a half pail of water, (add the water first) then take a brush and apply the mix. The bright copper will almost immediately appear and the oxide disappear. Next, get some fine Polishing Compound, Walmart sells that stuff in Auto Dept. and using that compound on a rag, polish that copper to a bright luster. The finer its polish , the longer it stays before oxidization will occur. You can give the final polished copper a coat of clear wax to maintain its luster. Do not use a Poly base wax, those oxidize over a period of time and are difficult to remove.
