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

It was very easy to use and had a minty smell so it wasn’t hard on the nose. I used it on newer stainless steel items and it worked perfectly. I used it on bathroom fixtures that had not been ever cleaned with a stainless steel cleaner, and I had to clean them a couple of times. They still are not perfect but I think a third time will do the trick. They make the stainless steel look new! Very beautiful. So give it a try and keep trying. If the first application on existing long term stains doesn’t readily go away.

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 live full time in a luxury RV. After about 2 or 3 years, the toilet was not staying clean. Although I didnt have other signs of it, I figured it had to be due to hard water scaling. The porcelain bowl seemed like the finish had been ruined on it. Anyone thats used an RV toilet knows that they use very little water. They flush more on gravity than on the principal of water. So if the sides get chalky stuff sticks and even stains. Its beyond gross. But you also have to take the seals into account. So harsh chemicals are out. Tearing down a toilet to replace the seals ranks up there with bikini shopping in February... It may be necessary at some point, but its not going to be fun! Since I refused to use harsh chemicals, I knew the finish hadnt been ruined by anything. I had tried leaving it full of vinegar overnight, but it didnt resolve the issue. It didnt even remove all the staining. Neither did my usual mixture of laundry powder, borax, powdered water softener, and laundry soda. So... I decided to give this a go! I drained all the water out and slathered this on. I let it sit about 20 minutes. Then I added a cup or so of water, and used my chosen implement of destruction... A drinking glass scrub brush. No buffing with a cloth or anything. It was much improved! So much so that when I decided to repeat this tactic, the product, which is quite thick, wouldnt cling to the sides... It just slid down to the bottom seal. But I used a piece of paper towel and reslathered it all over. Let sit. Did the water and brush thing again. It has a faint mint smell, so it doesnt require having to open all your windows and turn on the roof vent fan. A deodorizer it isnt... But thats not what I bought it for and really appreciated its mild scent when my head was 8 inches away from a toilet full of it! Omg. Its like my toilet is brand new. Both the porcelain bowl, as well as the vinyl seal flap! Its so slick, you cant even get toilet paper to stick on it if you wanted to. Im definitely impressed! And it doesnt seem to have caused any harm to the rubber seals or vinyl flap. Now, I admit that it was only $12.99 when I bought it. I do think that price was more than fair. Im not sure Id pay $20+ for it. But then, Im on a fixed income and watch every dollar. But compared to the outrageous price a new porcelain RV toilet would be... Its definitely a bargain at almost any price. Id definitely recommend trying it on hard to remove scaling and the stains that come with it from rust or such. From what Ive read, the problems folks have had seem to come from being too aggressive with it. So being lazy with this stuff is the way to go... Which works perfectly for me!

Tried all the other tricks with vinegar, baking soda, lemon etc. This stuff is like a smooth green paste that is easy to work with. Like others say, you do have to do some rubbing before it starts to take the rough stains away. At first you feel and hear the roughness and then it slowly feels smooth. Then when you wipe it away you can’t believe it!! Super stoked!! Did a 10 yr old shower glass enclosure that I was about to pay to be replaced. It worked fine for me with paper towels or sponge. I had an issue with glass scratching when I tried a drill brush attachment so I stopped using it and went back to paper towels and sponge.

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!!!

easy to use and provided the best results I have experienced when compared to other products i have tried

Admittedly our shower wasn’t terribly dirty but after dreaming about a new bathroom for about 9 years I finally had it renovated about four months ago. I was so thrilled with my cool, modern glass shower door and vowed to keep it looking like new! We live in as Arizona so we have extremely hard water, so kitchen and bathroom cleaning products are a never ending source of frustration for me - as nothing seems to budge the hard water spots and buildup. I have tried about 8 different products at least, plus one recommended to me by a family member who said it was the best they had found and they had also tried many brands. At best they removed maybe 75% of the white spots and hazy film, but never really got the shower doors clean. I felt sad every time I went into our new bathroom! I got this cleaner today and excitedly decided to clean the shower immediately. As directed, I used a small squirt on my microfiber cloth, wiped it on and 70% of the haze disappeared with one light swipe!!!!! I couldn’t believe it! I used maybe a bit less than a tablespoon per door. After the first swipe I needed to rub a little bit harder to get the more stubborn marks off but I was only using a microfiber cleaning cloth. I finished the doors in about 15 mins including rinsing and drying - I rinsed with our RO drinking water to avoid the mineral deposits and decided to use another cloth to dry the wet doors so there would be no watermarks. I was thrilled with the results! I was so happy that I decided to tackle the Kohler porcelain bathroom vessels that had a buildup around the pop-up that nothing had been able to budge. That took a lot more effort than the doors but with some scrubbing with a small cleaning brush and Bio-clean, I got them perfectly clean too! Most of the marks came off with just a cloth, but I needed to use a brush for some stubborn areas. My bathrooms look brand new again and I have renewed my vows to keep them looking like that now that I know that it is actually achievable with this product. Before, I would spend ages cleaning, but I never really felt a sense of achievement because I couldnt get my bathrooms to look perfectly clean. Check out my pics for before and after photos of my shower door and one of my Kohler vessels. The sink staining might not look too dramatic BUT these sinks were only put in about 6 months ago (and pretty much immediately got this build-up, thats how bad our water is) I had previously tried everything to get them clean from non-abrasive to abrasive cleaners, to lime remover products. Nothing budged it until I tried Bio Clean. Im actually so excited! I know its just a cleaner, and I know that I sound like an infomercial, but I hated feeling embarrassed about my bathrooms! Plus for three sinks, and a large shower door I used about 3-4 tablespoons (maybe less) Sign me up! I will be keeping a bottle upstairs and down from now on, in my cleaning totes and hope that it is NEVER discontinued!

i used it on heavily stained hard water stain glass...it worked very well and my shower glass door looks brand new.

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!
