"This product really works! Our guest bathroom had horribly hard water damaged glass shower doors. It was super embarrassing. I had tried other products but they never completely removed the hard water damage. This product was so easy to use and it completely removed all signs and traces of hard water damage. Works just as advertise. I'm a very happy camper and I would by again!"

“I was doing some research online and came across Barry’s products. I’ve been having issues with hard water for a while and everything I tried didn’t seem to work as promised. This spray literally dissolved the hard water in seconds! A little elbow grease and I couldn’t be happier!”
