Pro-Strength Hard Water Stain Remover, Industrial Strength Hard Water, Mineral, Rust & Soap Scum Remover, 35 oz Bottle

I had rings in my toilets since I moved in over a year ago. I have scrubbed and tried multiple products.This stuff worked! And it wasn't hard scrubbing.I took some of the water out (I did not want to turn the water off and drain it fully.)I put the stuff on the ring.Let sit 10 min (on 1st toilet I did only 5 min and I had to scrub a lot harder!)Used an old scrubbing kitchen sponge (the green kind, retired from the from kitchen) to scrub lightly and the rings were goneI can't recommend enough and I only used about 1/20 of the bottle for all three toilets.I also tried to do the window in my shower.. it looks much better but not 100% (must squeege or it you just get spots)Warning: this is caustic chemical. Read and follow the warnings!I would also recommend safety glasses (you can get a cheap pair, probably on Amazon). You do not want to get this in your eyes! And do NOT mix with other cleaning products.Suggestion to the manufacturer: smaller bottle! We do not need a whole bunch of this stuff sitting in people's under sinks or garages and no one needs this large of a bottle (unless they are planning to do this professionally) and include a cheap pair of safety glasses.I had before during and after pictures but they won't load.

Trust me, this is the solution you’ve been searching for. Awesome, awesome, awesome!

This product has helped the stains inside the toilet bowl; IMHO, I'll continue to apply the product until all the stains are gone. Might need a stiffer brush, IDK. It smells great.

I was so hopeful. I tried many different things prior. I read the instructions and did as it said. I loved it on scrubbing for 3 to 5 minutes. I rinsed it off and at first I thought it was working but I was wrong. So I cleaned the rest of the shower. I did well cleaning the walls of the shower. However, I went back and did the glass doors one more time. This time I left it on longer scrubbing and scrubbing. I ran stood off and it truly had no effect on the hard water stains to the glass doors of the shower. I was very disappointed. 😔

Today I used the water stain remover for the first time on my fiberglass shower. It had a year's accumulation of blue and red mineral stains from well water plus some soap scum, and I'm really happy with how well the product worked. I applied about a teaspoon full at a time to a dish scrubbing pad and rubbed it on the stained shower walls. In seconds the stains wiped off and pretty much disappeared. Easy, no hard scrubbing needed, and it rinsed right off. I expected a lot of fumes and strong oder, but it was mild and no big deal. This stuff is exactly what I needed and I'm very happy with how fast and easy it worked.

Works about the same as others but definitely not better. Supposed to remove soap scum and hard water marks. Soap scum, yes. Hard water marks, not so much.

Works well

Lo he usado y no me ha resultado bien sigo con el problema en los vidrios del baño, no funcionó como esperaba
