I use THIS on my diamonds and white gold rings in conjunction with my Salton Jewelry Spa and it looks GREAT!!!
What I learned NOT to do is NOT to use a jewelry polishing cloth on white gold. I did this when I first got my Jewelry Spa to take off the "tarnish." With the tarnish, the plating began to come off and my ring turned yellow within 4 months. I got them replated and now I only use eyeglass cloths to dry my rings after cleaning them. I''ve been doing this for 5 months and now there''s no yellowing.
