Found a little Stanwell pipe in a tobacco shop today on my way home from the airport that I really liked. It's a Stanwell (bent, sandblasted, paneled billiard), the stamp on the shank says Nordic and 255. I had never seen one quite like it before so I grabbed it up. Anyways, It has a metal band, copper and I'm guessing nickle. The copper is a little tarnished, not turning blue or anything, just a little discolored from being handled most likely. Any suggestions on what to clean/polish it with? I didn't want to go putting any harsh chemicals on it, I don't know if they would hurt the stain, or me I read somewhere that white vinegar and baking soda mixed into a paste works on copper pots, but I wasn't sure what to use in this case.. Thanks.
