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

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

I cant tell you how great this stuff works. You do have to use a little elbow grease, but not much. I have had FL hard water stains on this shower door glass for quite some time. This stuff made it like it was just newly installed. It also took stains off other bathroom fixtures that were brushed nickel. Will take paint off so dont recommend that anything thats painted.

Lo use y la verdad me sorprendio lo bueno que es, había tratando mucho las puertas de los baños y no habia podido remover el javon o agua que tenia, no lo pude remover todo a la mismas vez, pero si funciona..

This Is the best cleaner I’ve ever used for my shower door that you cannot ever see thru. No matter what we used or our cleaners used, nothing worked! Now, you can see thru and its clean and shiny. One more cleaning and it will look brand new. Not bad for a 30 year old door!!! Buy this now!

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.

I used other products while trying to remove mineral stains from the Hot Tub. I say trying because they didnt work. This stuff was effortless. Worked great.

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

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

Glass cleaning and bathroom shower doors are shining.

Omg it’s really work I try every thing but this one is great!!!!
