I did a small experiment and used this. I covered everything other than the metal clasp with a paper towel and masking tape. Then cut a one inch square of the polishing cloth. Very gently polished for about 10 minutes. The results were very good. Not perfect, but minimized the scratches by 95%. I tried to photo the results, but didn't get a good picture. But I would do it again as needed.
I tried scratch removers from Lowes but was too afraid to do more than 10 swipes. Does anyone know if the clasp is true stainless steel or just coated?
