Promising review: “When we moved into our new place the shower doors looked like they had never been cleaned before. I tried at least 10 different products and methods to remove the hard water spots but nothing even made a dent. Bio Clean, however, was like a magic eraser! I scrubbed each door for about 10 minutes and it was incredible! I’ve never written a cleaning product review before but this one is worth every penny.” —Shane B
