Grout Cleaner, Hard Water Stain Remover, Remove Spots on Shower Door, Clean Tile, Fiberglass, Windows, Grout Lines Bring It On Cleaner 16 Ounce

Absolute magic for the price point. Makes your glass look brand new and removes the water stains effectively. I did not have to put too much pressure. Use a sponge and scrub lightly and leave the product on for at least 10 mins before washing off. Do be careful and read the label. The paste is dangerous to eyes and skin, so wear gloves and goggles before using. There is no scent with the product - it is a paste so you do not need to worry about breathing fumes.

I have rental properties with A Lot of glass in the bathrooms. Nothing else has worked for me to get the water stains out other than this product!! Worth the money!

Works very nicely didn’t get out some of the real old stains. I’m a cleaning lady and I have a client that just bought a home but I do think overtime it will remove all of the stains so I’m happy with it.

Works great on hard water scale, and other stains. Good stuff been using for years 👍

This stuff is amazing. I live in an area of Texas with REALLY hard water, and within a couple of years, my shower glass developed a glazed, calcium-streaked coating. The glass was so bad that it almost looked like it was glazed on purpose, and nothing I tried would get the calcium streaks off of it. This is the first thing that actually worked for me, although I will say that it took me a bit to figure out how to actually get it to work. USAGE TIP: The first few times you use the cleaner, DON'T wet the shower ahead of time, put a good amount on a sponge, and then put a thick layer on your shower glass. Then let it sit for about 5-10 minutes before using the scrubby side of the sponge to scrub the shower glass before you rinse it off. The first use made a big difference for me, but I had so much build-up that I had to do it twice before my shower glass was truly clear again. Love this stuff.
