(Bright & Clean) Ultimate Hard Water Stain Remover® for Glass, Shower Doors & Windows – Removes Mineral Deposits from Granite, Porcelain, Tile, Stainless Steel & Chrome

I cannot say enough good things about this cleaner! Let me tell you, my son’s shower glass was encrusted with hard water deposits. He’d cleaned. I’d cleaned it. I even let straight vinegar sit on it over night! Nothing was causing these water deposits to budge until this stuff came along. I did need to put some muscle into the scrubbing at first, but after sitting on the glass for a few minutes, it all started almost dissolving off the glass and chrome. I absolutely couldn’t believe it! None of us could! Here’s the before, after one panel was cleaned, then the whole shower. It was glistening in the light. Just look at it!

It actually cleaned my water stains on my kitchen black granite countertops. Did it's job and I recommend!

Had high expectations, but I also have stubborn hard water stains. It's not a miracle worker, but definitely the best I've used so far. Definitely need to put some elbow grease into the rubbing though.

It works. I had 20 years of hard water staining on my kitchen sink, shower fixtures and bathroom sink. Other things did not work. I only used a little muscle and 5 minutes and it all looks new. I live in Tucson Arizona. Our water is awful. But this took care of everything. I wish I would have taken before pictures. Thank you for a great product. I ordered 2 more right away. I want to use it on other stuff.

It is working, I don’t know how bad is your shower glass door but in my case it is working on metal parts inside my shower, works great on shower glass doors removing hard water deposits

This stuff WORKS! We moved into our house three years ago and the master bathroom has a glass swing door and a half glass panel. The water in the area is ridiculously hard and leaves water spots instantly and sever calcium deposits. I have tried MANY products to clean this up. CLR, RainX, Barkeepers Friend, cleaning grade vinegar, even Irish Springs 5in1… NONE of them completely removed the spots. Some barely even touched them, some reduced them but still visible in the right light and angle. I took my Ryobi Power Scrubber, the brush attachment, dampened it and sprinkled this product on the brush. I let the scrubber do the work and rinsed when I felt I had gone over the area enough. The RESULTS were AMAZING! I wiped the water away thinking I would still see a hint of spots, but NO! It literally looked like brand new glass! This stuff will be a staple in our house permanently!

I tried it once on shower tiled floor with light white calcium or lime deposits. I do not see much of a difference. I used a mini scrubber with it. I will try it one more time . I think it should be like a paste.. not dry powder like it is.

My front windows are etched with years of lawn sprinklers spraying on them. I hoped that this product would remove the gray spots. It didn't. But the glass was badly etched.

Awesome stuff. My boat consistently has stains on the side windows since it is always out in the elements. This made quick work of that in and windows look good as new.

It removes hard water stain on shower glass enclosure

This works on hard water stains, I have tried everything, years of accumulations and this works and it is taking it off. It will take some time because of the accumulation but at least it is coming off. This was my last try at the removal or the shower would have been replaced, but not now, the shower is nice but those yellow stains YUK, I will be buying more of this. Awesome!!

This product works great !

Amazing product! Cleaned my windows on the outside of my house which get sprayed by hard water. Very little effort.
