BRING IT ON! CLEANER Hard Water Stain Remover - Soap Scum, Calcium, Lime Scale, Remover for Shower Door, Tile, Glass, Fiberglass, Bathroom, Sink, Stone, Door 32 Ounce

This requires some elbow grease to get rid of really calcified hard water stains, but it can return even a chocolate brown shower from the 80s into a very clean shower from the 80s (until we get a remodel done) 😊 Because the shower is a plastic liner, I used a no-scratch sponge pad. This stuff even worked on the glass door. It works, I had to go over this shower in layers, cleaning, prepping, recaulking. When it was clean and dry, I used Gel Gloss on the walls only. This is the final result after hours and hours in there, scrubbing and cleaning, waterproofing and polishing. But it’s clean and sanitary.

My bathroom shower door had a lot of stains.. from years.. this product removed them effortless.. I was amazed for it's cleaning power, it's a favorite cleaning product now and always.. don't think about it and buy it.. it is worth it.. it's safe to use and it functions and it is very effective..

I now have used it twice on my shower doors. It works so well on hardwood floors water stains. I have friends using it now.

I recently bought a home and I don’t think the previous owner had ever cleaned the shower.. you could not see through the glass there was so much soap scum and hard water stains. I was able to remove the soap scum but couldn’t find anything to touch the hard water. I tried magic erasers, CLR, bleach, steam cleaner, everything. I googled best products to move hardwater stains and found this this was super cheap. I figured I’d try it and let me just tell you - it works. I used the a damp scotch scratch free blue pads with this and immediately saw a difference. The bottle says that you may have to do it a couple of times to remove all of the buildup, which was true. So far I have done it 3 times (essentially just 3 days in a row) and almost the entire door is spotless. All I have left is around the edges that I just didn’t focus on. I didn’t have to put in a lot of pressure, just circular motions as it says. It was honestly surprisingly easy. I love how thick the stuff is too because it doesn’t just run down the glass - it stays put. There is literally no smell and with the size of the bottle it will last forever. I definitely plan to use this stuff movin forward and am excited to see what else I can clean with it. Both pictures are technically after I’d already used it but the first picture is right at the edge showing where I need to do it some more. The second picture is in the middle of the door and it is spotless! Now that I can see through the door, I’ve got to get better about keeping the dang floor of this shower clean… the texture of the shower pan just attracts dirt lol.

This works!!! We have hard water where we live. Dark grey quartz counter tops in the bathrooms, it’s almost impossible to keep the stains away. I’ve tried everything on the planet to remove the stains and nothing worked, until now! 100 recommend!

My tub has a glass surround and the glass is about 10 years old. We normally use Dawn and vinegar but I found it to be less and less effective over time. There are some really stubborn hard water stains that don't come off. I searched around and found this product with glowing reviews on third party sites. Amazon reviews were also pretty positive so I decided to give it a shot. Pros: It just works. Goes on like a gel/paste and takes the hard water stains and soap scum out with a little bit of rubbing with a scrubber. Cons: It's not that much better than Dawn with vinegar. If the dawn combo is a B, then this cleaner is a B+ The really stubborn hard water stains are still there, Even after 2-3 rounds scrubbing and application. Mind you, I've tried baking soda and vinegar, a power drill rotating scrubber, and the whole host of off-the-shelf cleaners. Heck, I even tried a power washer on the glass. Nothing really works "as advertised" If your glass is as old as mine and hard water stains are a stubborn is mine, this cleaner is good but not great. Don't expect it to work magic on your glass doors.

Great product , remove stain with easy wipe.

It worked for me. It says right on the bottle, “Removes hard water spots”, and at the top of the list of items on which to use this product is “Glass Shower Doors.” I bought this product for exactly that -to remove hard water spots (and scum) from my glass shower doors. It worked like a miracle! I have used this shower for 4 years and never squeegeed, cleaned, or treated the glass - so there was a substantial film. I was dreading cleaning it, and had put off tackling this project because I thought I wouldn’t be able to find anything that worked, and I didn’t want to waste my time and energy for an unsatisfactory result. I am very pleased to have found this product on Amazon - it had many good reviews, so I was willing to spend approximately $20.00 to try it. If that’s how much it costs to get a product that actually works, then it’s worth it to me to bite the bullet and do it right the first time. I followed the directions on the bottle. I applied firm pressure as I worked - I did not have to “scrub really hard.” I could see the stains clearing as I rubbed, which was certainly encouraging. After rinsing, the glass door looks brand new. You have to be very close to see that there are small specs of residue remaining on the glass. Perhaps a second go-over would eliminate these, but I’m extremely pleased and completely satisfied with how the door looks. I’m not going to do another coat, as no “casual observer” would notice the tiny spots that remain. If you have hard water spots and years of scum on your glass shower door, I recommend you try this product. It exceeded my expectations. I am extremely happy with the result, and grateful to the creator of the product for making something that actually does what it claims it will do. In my attached photo, the glass on left has been cleaned with minimal effort one time. The glass on the right is untreated. Hallelujah! P.S. I just gave my bottle to a friend who hasn’t found anything that cleans glass shower doors - until now! I am going to order another bottle for myself!

Si limpia bien vidrios de baño

Best product ever, I have tired a lot of products on my windows to remove hard water stain this is the only product that is effective you apply smaller amounts then scrub in a circular motion and you see the stains go away I strongly recommend this product

Great product, very happy

Probably one of the best shower glass scum cleaners available, I tried it 2 years ago, and have been looking for it again ever since my last bottle ran out.

Very good
