baileylab, they don't sell the jewelry cleaner but it's a well known brand and you shouldn't have any trouble finding it. I think a large jar is under $20. I personally prefer my silver to have a light patina - I don't like it blindingly clean. In fact, I just got a special order H bracelet of oxidized, distressed silver. I know it's not for everyone (it's designed to come scratched, and heavily marked) but I really love the look and sold the identical "clean" silver bracelet I had when I got this one.
I tried this on at Madison a couple of weeks ago -- very cool!!!
