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

Great product ... you need to give it a try!

This Bio Hard Water cleaner is amazing! I used to not like to clean windows but not I will even clean yours!!! This product is great for hard water removal! Wipe on and wipe right off!!! No streaks… nothing but clean shiny windows!!

I have to be honest when I first purchased this item I had my doubts that it would remove my hard water stains from my shower glass door. After rubbing it on my shower glass door for several hours it actually removed 90% of the hard water stains on my shower glass door. This is a fantastic item. I highly recommend!

I really did not expect this product to be this amazing. It was just delivered and I thought I would give it a quick try on these heavily crusted windows. It goes on like a paste and polishes off easily. It removed ALL the calcium deposits within minutes. You also only need to use a small amount. You can see how badly stained the lower window was by comparing it to the one above that I have not cleaned yet. This is the best value for money I have found on Amazon.

I have hard water stains on my shower door and walls.. this did not remove them

I purchased a home in which every toilet had prominent mineral stains inside the bowl. I tried multiple products that said they could remove the rings, but none even touched them. I saw this product advertised on Amazon, read the reviews, so I bought it figuring it couldn’t do any worse than everything else I’d tried. I let the water out of each toilet bowl by turning off the water inflow valve and flushing, then squeezed some Bioclean directly onto the stain. I used a toilet brush, scrubbed it in sections quite vigorously, and - - Voila! The stain was completely gone! I did this in all of our toilets and each was like new! I also used it to remove some stubborn rust stains from a bathtub in which nothing else I had tried worked. I did have to use a brush and elbow grease, but every bit came off. This product is truly amazing!

Incredible. Removed hard water stains from windows without even rinsing in minutes. Vinegar wouldn’t touch these stains either.

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.

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.

Im not sure what kind of dark magic this is, but some one should call the church. This stuff is amazingly easy to use with immediate results. On my all-glass shower surround, I have used magic eraser, Windex, CLR, Scrubbing bubbles, and there was always a residue, bulging muscles and a need for Ibuprofen by the time I was done. I was almost nonchalantly applying this stuff on (with only 1 paper towel for the whole massive shower) and then just rinsed it off with water from the shower head and it looks like new...for those in the back, IT LOOKS LIKE NEW!!! And now the water is beading up and running down like a thing of beauty. I may have whispered I love you to the bottle. This stuff is amazing.
