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

It works.

I don’t often write reviews. Great Product

I was very impressed with this product. It really does work on hard water stains. Even the worst of them you just have to go at it a bit at a time but it removes the stains. I’ve been cleaning for 30+ years and this is the BEST hard water cleanser.

I had a rust ring around the drain of my bathroom sink-also with polished nickel fixture so limited in what could be used to try to remove the stain. I had used CLR which has always worked for me…not this time. This green stuff removed it almost instantly. It removed it so we’ll I wish I had taken a before and after shot! I was hesitant to buy because I thought this cleaner was a bit pricey but Wow…. It really worked for a rust stain that nothing else was removing. No damage to the fixture finish either.

Tried lots of different products to remove hard water stains on my glass. Nothing worked. Until I tried bioclean! Had to scrub hard three times but the hard water rings finally came out!

Not sure if works or what have to play a bit with it to see

This product was a little pricey but after using less expensive products with Less results I figured I would try it. My shower doors had 15 years of hard water Build-up and Could not remove it with other products. This product takes a little elbow grease but on the heavy areas did do it twice and the Glass door and shower look like new.

Its not every day I rate a 5 on all levels, but this product performed exactly as described and has exceeded my expectations for a cleaning product. I live in Florida, hard water and lime stains are in abundance. Ive tried all the popular brands, but nothing has worked as effortlessly and effectively as this. I used it on my shower glass and just for the heck of it tried it on my smooth shower tiles, both came clean with no effort. Wipe it on and wipe/rinse off.

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!

The only thing that has taken the hard water stains off of my shower door! I’ve tried it all and this was almost instant with minimal elbow grease involved. Amazing product. Will be looking into the protectant they have to prevent these stains in the future.
