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

I ABSOLUTELY LOVE IT! I don’t even have to scrub hard to get my doors cleaned.

This stuff is the truth! I cleaned a really yellow shower and bath. It’s now white!

I know this is going to sound like a crazy plant review but I am literally shocked by how well this worked. I am a 50+ man who does not leave reviews but felt compelled to share my experience. I have a tempered glass shower glass over a half wall, we had spots, tried everything, steamer (multiple times) in conjunction with CLR, vinegar and some other cleaners nothing got rid of the spots, we bought a squeegee and figured we had to live with it and just try to limit further accumulation. I dont even remember what turned me on to this (50 going on 80 LOL) but I figured what the hell give it a try and it arrived yesterday. Without any scrubber just a rag in my work clothes I decided to give it a try before dinner, OMG the glass was so much clearer, it came about 90% cleaner than it was,I probably even used too much. Tonight I was working outdoors and took a shower before bed and decided to give it a second go, well with barely a couple of squeezes on same rag probably another 8% more cleaning and yes clearer again, you have to look really closely to see evidence of water spots, Im figuring 1 or 2 more times and even that will be gone. You nay think multiple applications is too many but I am hardly putting any elbow grease into it, regular terry cotton rag, no scrubber and I am very impressed. Oh and the squeegee we use it actually glides across glass better too, you can tell there is less residue causing friction. ON a side note while rinsing rag i decided to wipe the fixtures (I was in shower using shower head to rinse) I had no idea my chrome was so dull, then a quick wipe of my shaving mirror - same result crystal clear, not a big deal but its nice to see myself better. Unless this stuff turns out to have come cancer causing ingredient or some other crazy side effect I dont yet see I am SOLD, I will use this forever and Im sure I will find many other uses too. Lastly it rinses off easily too. QUICK UPDATE - shaving mirror wasnt a good idea, as others have pointed out, not all glass is glass, my shower mirror must have been a plastic resin and now has micro scratches on it, no detraction from review of product, Im still amazed at clarity of tempered glass and shininess of chrome fixtures.

I bought this for our one piece fiberglass shower and glass doors. Only tested it on one glass door. It took quite a bit of elbow grease and a scrubby green kitchen type sponge. It does make the glass better (my door is not etched or glazed, so I can’t vouch for those type of doors) than it was, but I think it needs more than one application. In my case, my shower has a lot of build up, and I have not found a good product or method over the past 15 years in this house, so I’ll update after I try it on the whole shower and a couple of times. I did not get a tool to scrub it, as I assumed the basic green sponge would do the trick, plus I don’t want to scratch the fiberglass of my shower. I have a bristles scrub brush which I’m going to try on the fiberglass next. It rinses off easy, so it’s good. It doesn’t have a strong cleaner smell, imho, so that was not overwhelming for me. It depends how sensitive you are. I just hopped in the shower before taking a shower, and tried to work it on the surface. As I said, a lot of elbow grease, so give you some time to work it in. It’s a creamy consistency, not really gritty, so it stay where you put it mostly. I wonder if after scrubbing, I could leave it on for a bit? I think it does better than any CLR, limeaway, scrubbing bubbles, etc etc product, so it’s worth a try. Once I get to work it through and clean, I will post update with before and after photos. I also read about using jet dry on the surface to keep water from forming scaling again, like on your dishes. So that’s something to try too next.

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 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.

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

This cleaner does a good job on tuff water spots on glass

Cleaned my shower door and the tray of ice/water In refrigerator door!!!!

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.
