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

Repainted the bathroom and figured I would have to buy a new shower handle and 6 inch diameter bezel from Moen. 15 years of hard water build-up. But I took a chance and bought some of this. Didnt really expect much. but the new fixtures would cost a lot. So I gave it a try. Smells like wintergreen. Seems like it doesnt have any strong chemicals. So, when it showed up, I applied it with my fingers to the bezel (didnt take a before photo because I didnt expect much). Five minutes medium pressure rubbing with a microfiber cloth. Couldnt believe it. Plumber who was here working on a drip said hed never seen anything like it too photos of the bottle. Then I took a before photo of the shower handle did the same quick cleaning and took an after photo (attached). It seems impossible. Now I am running around the house cleaning every fixture and glass shower door, and shower marble, I can find. This product should be in every grocery and hardware store in the land. Astounding!

We live in an area with notoriously hard water. For years Ive juggled using a slew of various green cleaning products (including making my own) to take care of rust, hard water stains, and soap scum. Finally desperate and willing to bring out the big guns, I bought this along with another brand to see how they stack up against one another. This one was the winner in that it was MUCH more effective on its first use. The other stuff, while still more effective than the less expensive cleaners you can get at every local store, still needed multiple applications and tons of elbow grease to remove the stains (if it did at all). Both products have the same wintergreen(?) scent. The smell is much stronger with this one, though, and to a very unpleasant degree. I had the TASTE of the scent in my mouth for nearly a week after the last time I used it (and I wore gloves). It affected my taste, normal saliva production, and was altogether a bit disconcerting. But did I mention the stuff works? lol I guess Ill use a mask next time and see if that helps. I like that this cleaner is green in color b/c it helps ensure you arent missing any spots in application or in the scrub-off process. (The other one I tried was an almost translucent white.) One last thing: while I am praising this product for doing what it says, its not a miracle worker in that you slap it on, wait a few minutes, wipe, and your bath tub or shower is sparkling like it just came out of the showroom. You still have to scrub (and then rinse and then wipe dry). But its therapeutic for me to scrub it and IM SO HAPPY that years of build-up are finally coming off. I will definitely buy more but just figure out a better ventilation situation if possible.

I don’t do reviews much, but I had to for this product! Best thing ever for hard water stains. We have a big window in our master shower at the property we just bought and we thought it will need replacing because looked like previous owners never cleaned it. 2 window companies came out and said it will cost us about $700, well before doing the order I decided to try this and OMG!! With a little elbow grease it worked like a charm ! On the picture on the left you see before and on the right after.

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!

This product did not work to remove water stains.

Sparkling cleaned fiberglass shower stall. So much hard water buildup over the years. Scrubbed off and rinsed within 10 minutes. Amazing product. Soooo sorry no before and after pics. Amazing miracle product!!!

I’m so impressed, I gave a bottle to my house cleaner to use for her other clients. The cleaner actually lasts for the 3 months, as claimed!

I bought this based off other reviews- and it really does work! For my sample test I just used a paper towel, but to really clean the doors more efficiently I used one of those white scrubby sponges- it does take a little elbow grease, but not much. I Just do about a 6 wide strip every time I get into the shower so it isnt so tiring to do all at once. Warning though- dont try this on stainless steel- it scuffed up my fridge (and no, I didnt use a scrubby sponge).

Rediscover what you once thought was lost! Who knew there were words or branding on this fixture? (hint, not me) My apartment was nearly new when I moved in; however I noticed the bathroom fixtures lacked that chrome shine we all know and love. Honestly, though I had lived with hard water in the past, I dismissed the lackluster shine on inexpensive fixtures. Over the years I have tried everything to regain the shine I knew was there, somewhere, under what was now clearly layers of hard water stains. My fave bubbles that scrubbed, something that promised 4x the clean when it came to the stubborn scale -- everything. Fast forward to a brain break scroll through Amazon -- the kind where your mind goes blank and for some reason you just endlessly look for some unattainable product. I ran across this wonderful stuff and then promptly added it to my wishlist. It looked awesome, but Im a small business owner and getting rid of an uncrackable film in my bathroom isnt always top priority. But wait! Thats what gift cards are for! Yes, my friends, I purchased a hard water stain remover as a treat for myself. This bottle of green goo, that smells kind of like an antacid tablet tastes, it was finally mine! And here we are, with me gushing over a cleaner on Amazon. For anyone wondering I do not own a fancy drill bit that does all the scrubbing for me (though super jealous of those that do). I spread a thin layer over the entire object or area I want to clean, then work with a double sided sponge and tackle a section at a time scrubbing in circles. I then move on to the next section and repeat until the sparkle returns. So, while it does take work, you can get results with your normal cleaning tools and a little elbow grease.

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.
