Promising review: "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 five seconds, it's five seconds. If you leave the jewelry for more than that, It will be ruined. This stuff works wonders. Also, it 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. So, I submerged them for five seconds and MAGIC!!" —maria rosello
