I have been selling my old designer silver jewelry online and trying out different cleaners to remove tarnish (but not harm the gemstones or pearls.) I spent a lot of time spraying different silver jewelry cleaners and polishing with silver jewelry cloths. That is until I found this product. Now i just drop the earrings (posts included), bracelets, necklaces, charms, etc. into the container basket and leave them for about 60 seconds and Voila! Bright and shiny silver appears. Some of my pieces required a longer soak (2-4 minutes) because of tarnish on ornamental beads and in cracks and crevices around mounted gemstones. But I just wait, take the jewelry out, rinse it in cool water and polish it with a soft jewelry cloth. I have gotten nothing but rave reviews from my customers on the condition and appearance of the jewelry I sell. I highly recommend this product to anyone who wears, buys or sells silver jewelry. It is worth every penny.
