Ok, here it is... My well intentioned Mom decided to clean our copper range hood during her stay over the holidays. Unfortunately for us, her metal care skills are seriously lacking. There is quite a bit of grease build up on top of a wax coating and she decided to scrape it off, down to the bare copper. So now we have massive scratches. What is the best way to blend this area back to the surrounding areas? Can this even be done? It is a medium copper patina w/a wax finish. Any tips or tricks would be appreciated.
