It works! It really works
Skeptical about the product since I try a few for my shower glass door and sides. Have hard water on my region and should invest on a water softener. Try so many and don't removed the spots completely until saw on the TODAY SHOW, not a infomercial purchaser, but desperate to find a solution that looked on online and bought it. They have a customer until I install a water softener.
