I was walking through the local mall a few months ago and a guy at one of those kiosks in the center of the pathways called me over to look at his product. Usually I just ignore them and keep on walking but I noticed he was selling a new glass and jewelry solution and I knew that my jewelry and my fiances engagement ring desperately needed a cleaning. So the salesman took our jewelry and soaked them in this container filled with Sparklean glass and jewelry cleaner. We talked for about five minutes about the product and I kept thinking that this guy better not ruin my fiances ring with this solution. he removed our jewelry and wiped it down and we took a look at it. Let me tell you, this Sparklean stuff is good. My jewelry was scuffed up and dirty and it looked brand new after 5 minutes in the Sparklean solution. My fiances ring was sparkling like it was brand new. So we bought a bottle and brought it home to use on our other jewelry and on our mirrors, car windows, and pretty much anything else. Sparklean won't leave streaks or residue on glass and it cleans it unbelievably without the use of harmful chemicals like ammonia. The only disappointment I have is not buying the larger sized bottle when I had the chance. I know those kiosks in the center of malls can be very shady and untrustworthy but this one was a real find.
