I just went on your site this morning because I had a lot of jewellery to cleaned. I found that all glitter like gold. The other things are glittering as well. I always used the commercial brand but it ruined quite a few things.I Used all the things that were called for and it worked out fine. If you have a high piece I just put it in a smaller container.
