Bio Clean Hard Water Stain Remover 40 oz. (20.3 oz.)

I had tried ever cleaner that claimed to take off hard water stains and nothing worked. I have a closet full of useless product. This was the first product to actually work. My glass looks brand new.

It was very easy to use and had a minty smell so it wasn’t hard on the nose. I used it on newer stainless steel items and it worked perfectly. I used it on bathroom fixtures that had not been ever cleaned with a stainless steel cleaner, and I had to clean them a couple of times. They still are not perfect but I think a third time will do the trick. They make the stainless steel look new! Very beautiful. So give it a try and keep trying. If the first application on existing long term stains doesn’t readily go away.

It removed the hard water build up on my shower doors!

The water here in north Texas is the worst. Our glass shower door had so much hard water build up that it always looked dirty no matter how much cleaning or squeegee-ing we did. This product was easy to apply, easy to remove, smells pleasant, and left our shower glass sparkling clean. I would highly recommend.

I am impressed at how fast and how well this works. Prior to this, nothing at all worked. My glass top stove looks amazing!

Love using this product for cleaning shower glass doors. Gets the hard water stains off first try. Its my go to for my cleaning business.

I thought this would be about as good as what Ive always used. totally surprised at how well it worked.

I do professional tile and glass restoration. I have a special go to product not available to the general public. It is pricey, which is okay when you rely on the results, but..... closed quarters use can bring about wanting to put on the respirator. Saw this, read the reviews heard the moaning about elbow grease etc. , but that doesnt register for someone who uses a Makita polisher with 3, 5 and 7 pads to wrestle off the tough stuff. If this stuff works 90% of what they were touting, then I could use my back-up stuff to finish the rest. What I want from this product is its engineered abrasives and a bio friendly chemistry. She works... keep it wet with product until you see the soap scum and water deposit actually begin to free itself from the tile or glass. Then you can continue to let it naturally dry out as you still buff away. My first experience with this product was on a very worn outdoor tile shower with major deposits. Used 2/3 of a 20oz. bottle, that bad. I have not used it on glass yet, but from some of the reviews I have read about glass scratching, here are a few things to consider: Glass is real strong. Particulates like metal and stone or grit will scratch it though. Some folks have thin shower doors they think are glass, but they are actually Lexan, a type of plastic. Others thin glass doors are, of course tempered. Tempered glass from the orient is notorious for the cheap layer that is the tempering. There you may get some swirls from this type of abrasive. I will write a follow up when I get some glass done. Meanwhile, keep your cleaning cloths or pads real clean. Do not throw micro-fiber towels on the floor, they will pick up everything. Those small rocks and dirt will find a way to hang on even after washing. So give extra care to them.

Hard water stains that have built up against the shower walls the past couple of years completely came off like butter!!

Moved into an apartment with already prominent hard water stains and tried lots of different hard water cleansers, sprays, and scrubs to try to improve it. Was recommended this by an Instagram Reel I think and I’ll be continuing to buy and use this product! I used a soft dish wand sponge and this product to gently scrub in circles on my glass doors. I didn’t use a lot of pressure, just enough to spread and scrub a bit. When I rinsed, I was so shocked to see that my glass was transparent (when wet). That had never happened, it would always fog up and show the water marks. While dry, you can still faintly see the marks, but I think that’s just due to my low pressure or just being the first time use. The improvement is so much that I’ll recommend this and continue to buy.
