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

It was like magic on the ease factor and using very little to go a long way. I literally did no scrubbing for tough water stains on my 3 sided glass shower walls and door. What was to start a test, ended up being the whole thing in 15 mins. I did use a razor blade scraper for one section and not on another, to compare and they were virtually the same results in the same amount of time. There are not many products that will “wow” me but with the combination of low Oder, the power and ease, and a protective coating like Rain X left behind (that I know will work much longer than the store bought brands like CLR, Kaboom that I typically use). I am a believer of this product.

This cleaner does a good job on tuff water spots on glass

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.

This is a good product. We have very hard water that leaves spots on everything. We just rubbed it on and did a little scrubbing. Then we rinsed it off. Clean and clear!

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!

I thought this would be about as good as what Ive always used. totally surprised at how well it worked.

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...

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

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.

Incredible. Removed hard water stains from windows without even rinsing in minutes. Vinegar wouldn’t touch these stains either.
