Pipe: Is it copper? How to refinish? Help!
We have a long pipe (floor to ceiling) in our apartment. We *think* it is copper. It looks to be a dark brown color now (not sure if it is paint or what). A magnet won't stick to it and our apt was built in 1923 so copper seems plausible. Does anyone know how I can tell if this truly is what it's made of? And, if it is copper, how do I make it look shiny and new?
