Bioclean Hard Water Stain Remover 20.3 oz

House was built in 1996- pretty sure all our shower doors are from then- the hardware on them is the old brass. Anyhow- years upon years of hard water and soap scum, wouldn’t come off no matter how I cleaned or the product. Bought this in desperation, and damn!!! I’m impressed! I used the dry application method because I thought the extra scrubbing action would be to my benefit- first set of doors cleaned fairly well, but each door needed 3 passes, with rinsing in between. This definitely works better with the doors already wet. You don’t need a lot of product. A quarter sized amount did one entire door, inside and out, and my doors look almost brand new. A few more weekly cleans with this stuff and they’ll be sparkling perfectly. After use, the water doesn’t stay on the doors like it used to. There’s barely any drops to squeegee after a normal shower! Love this stuff, and the bottle will last me awhile. I will be recommending this product to friends and family with shower glass because it actually works, and removes old spots. Great product!!

Uh-mazing product! Removed SIX YEARS of hard water stains from glass showers doors in SECONDS! I wish I had taken pictures, but I was shocked and giddy! I have used every product you can think of and been disappointed by each of them! This one works...without the elbow grease or noxious fumes! BUY it! Worth every dollar!!

Tried so many products to remove hard water residue and nothing worked - until I came across this. Very easy to use, works quickly on slick, even surfaces, like glass. The plastic gaskets around the shower door, which I used to just replace regularly, look brand new. Had to use this several times on the marble counter tops, but it did finally work there too. Cleaning the somewhat uneven surface of our textured tile was easiest with a rotating, mechanical scrubber. VERY ECO FRIENDLY and SAFE as well, which is of paramount importance to us. This great product is a dream come true! Our sparkling bathrooms look like they were just installed.

This stuff works so well. It gets off hard water stains with minimal effort. It smells a little minty almost. I love that it’s a natural product with no toxic fumes or residue. That being said, there is no warning on the bottle about needing gloves - in fact, pictured in the bottle is a woman using it with bare hands. I did the same. Two days later, the entire inside of my hands is peeling. Have you ever done one of those foot masks where your whole foot peels? It’s like that. So far, it’s just one layer, but it’s pretty intense. I have snake hands and a clean shower.

Saved my sanity for my glass shower doors. I had tried basically every other product and cleanser the internet told me to. I had been trying for months to get the hard water off those doors. First time using this? 80% gone. I only gave the doors one cleaning each, I used the soft side of a scotch brite dish sponge and squirted this cleanser onto the dry doors. Wiping it all over, ensuring the doors were covered, I let it sit for a few minutes before wetting it and basically just wiping it off with the sponge and water. Massive difference. I'm sure if I go over the doors again for a second treatment they'll be back to their factory crystal clear self but... The smell gets to me. It smells heavily of bubblegum which isn't a scent I like. It dried my hands out horribly as well. It was not sticky in anyway, left the windows feeling great and clean to the touch. It's not too expensive, I bought the 20oz bottle and I know I'll get a few uses out of it. It only slightly foamed, which is ok. The color is a fun green, which made it easy to tell exactly where the cleanser was on the windows. There are four people who use the same shower in my house, I am sure I will get plenty of use out of this product.

My shower looked like an orange disaster on the tile and a horrible soap scum kinda thing in the walls and the door. This product cleaned up all of it with some minor scrubbing and my shower looks brand new. It also took off most of the rust build up in my bathroom sinks. I waited months after buying it. When I finally used it I was amazed. Seriously, buy this product and use a standard green scrub thing with it. You’ll get really fast results. I didn’t even have gloves on and my hands were fine so it it seems to be powerful but kind to skin, at least for me.

I am on city water, some of the hardest in the country, no water softener yet, this stuff cleaned the scale off of the chrome and out of the shower head. No unpleasant odor

With a little bit of effort, this stuff works! I've tried using CLR on my automobile glass to get rid of the water spots, but it wasn't enough to make a dent. Using a sponge, I was able to get rid of half of the water spots on the first pass. Using a little more elbow grease, and the water spots cleaned up nicely. Use just enough effort to start breaking a sweat with just the sponge, and I was rewarded with nice, clean glass. I was shocked how effective this cleaner is - it's better than anything else I've used before...
