Try a Copper and Brass polish called Noxon. Wipe it on, let dry, and
polish off with a soft cotton
cloth. The polish reacts with the oxide and cleans it. It still needs
elbow grease, but not as much.
Depending on the condition of the copper, you can get a mirror like finish.
Handle the finished piece with gloves.
