Promising review: "I have a 19-year-old master bathroom toilet that had accumulated some nasty stains over time, and regular toilet brushes and cleaning products just would not remove them. I decided to try this pumice stone, and it worked like a charm! Given the nature and severity of the stains, it required some elbow grease. But 10 minutes later, I have a new-looking bowl, and I see no signs of scratching." —Happy Retiree
