A "friend" without my approval, scrubbed off the patina of my beautiful copper kitchen sink until it looked like a new penny, then waxed it. I'm so angry! Is there a way to bring it back? I fear he ruined the factory finish forever.

Scrape off any wax or other foriegn materials. Once this is done, plug up the sink and put ammonia in it. You may want to water the ammonia down. Leave the ammonia to sit until the copper reaches a dark color, then drain the sink. Another option is to simply to let time take over.
