So, if this has already been posted elsewhere, I apologize in advance.
I received a DRI-YWET today in the mail and it was extremely tarnished. I wanted that beautiful bright look, so I looked up ways to polish copper. I read that you could use a lot of household items to do it, but the one I found to be the most interesting was ketchup! I used some with a bit of doubt, but I could see a difference as soon as I put it on, and the directions said to let it sit for a few minutes. This worked amazingly. I now have a like new DRI-YWET!
