Won this goldedge on eBay and was deciding what to use to try to clean the goldwash without removing to much. Well I decided to use household ammonia it works on gold chains and rings right, so I used a soft bristle toothbrush. I think it worked OK. Then used metal polish on the blade. The fingerprint is what is leftover from the stain on that side of blade. I guess I will need to get it polished by a pro to remove that.
