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

I have been trying to get hard water spots off of a picture window in my living room for years. I even had them professionally cleaned without success. I have tried multiple products that did not do the job. The window is partially over my head and behind a shrub which makes it hard to get to even with a ladder. I put this product on with a microfiber cloth on a mop head and used it to clean the window. Due to it being over my head I was not able to use much pressure. I thought this will never work, I cant scrub this very hard. I was amazed that it worked! Still a little streaky because I didnt dry it well, but the water spots are gone. Now for a good cleaning by the pros...

If youre questioning if you should try this or not... just add it to your cart now! We have hard water-we remodeled our bathroom Im 2016 and now only 6.5 years later our sink was looking so grungy because of it. Ive tried product after product with no results. I saw the reviews for this and it was on sale so I thought what the heck Ill try one more thing and Im glad I did. I posted pictures of the difference in our sink after using this product and 20 minutes of minor elbow grease. Amazing! Im so pleased!

To say that my place has hard water is an understatement. Sometimes, it surprises me that the water doesnt just plop out in flakes or chunks. The large sheet of safety glass for my bathroom shower accumulates hard water deposits might fast. Like, should I fail to squeegee the water off of it for a couple of days, it looks like someone tried to tag it with spray paint. Rolled the dice on this product and WHAMMO!! Hard water stains were destroyed with one application (I still need to go back and do a bit of touch up). Not only that, but the scent is kind of fun - think Christmas peppermints mixed with Pepto. It worked so well, and with such a modest amount of product that I think I may ever try to clean the hard water stains off of the tile in the shower!

I have frosted shower doors that no matter what product I used would not look clean. I saw this on Buzzfeed and read the reviews so decided to try it. It took some muscle but I got the doors and the shower stall looking practically brand new. I definitely recommend trying.

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).

Its not for applying and letting work itself, but it worths the work of applying and scrubbing because I did the same with many other products and it was frustrating. This product is effective and smells nice.

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!

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

I moved into a new place and the hardware was grimy that even bleach and peroxide and dawn dish soap wasn’t working to remove the grime on my shower head and faucet and the stains in the tub. This, however, actually worked! Highly recommend this. Also it smells minty, which is a nice touch. I would buy this again in a big bottle.

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!
