Bio-Clean Products, Eco Friendly Hard Water Stain Remover (20 oz large), Professional Cleaner, Granite

So, I was not getting any results cleaning accumulated lime/mineral deposits on a glass shower door. I just purchased a newer house for my wife and I, and the previous owner did not clean the glass shower doors for a very long time (10-12 years). EVERYTHING I tried did not work. So, using You Tube, I discovered your product. I first had used a 2" razor scraper on the doors (45 degree angle), which removed approximately 80% of the hard water deposits. Then tried Lime-a-Way, CLR, Barkeepers Friend, and %230000 steel wool. The hard water spots remained. My wife got me to try your "Hard Water Stain Remover". Without using a buffer, I applied your product in a test area. WOW! The mineral deposits were gone. It took me about 45 minutes to cover (scrub with a piece of cotton towel) the entire door. I don't usually write reviews, but your product deserves recognition/praise. I cannot believe that the door is restored to virtual new/clear, with NO scratches. THANKS--your product really works.

This stuff works really well on stubborn hard water stains! I will be buying this regularly to keep the glass shower looking brand new.
