This stuff its amazing! I cleaned all my jewelry in under 20 minutes. I read a review that said this stuff doesn't work and that it ruined a watch, I believed they left the watch in the liquid for too long, when I tell you it's 5 seconds, it's 5 seconds, if you leave the jewelry for more than that, It will be ruined.. this stuff works wonders. Also, the smell is awful. smells like rotten eggs! but it works!
I had bought a bunch of ALEX AND ANI bracelets that are cooper and after a little while they look awful, I was very disappointed because each bracelet is about $35. I have like 10 or 12... you do the math. So i said what the hell I'm throwing them away anyways! i submerged them for 5 seconds and MAGIC!! for the silver and gold tone ones as well. Hope this helps.
