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

This stuff is the truth! I cleaned a really yellow shower and bath. It’s now white!

You can scrub until your arm falls off but if you’re not using an effective product, it doesn’t matter. So I tried this stuff and I got the ugly water stains out of the toilet. Easily! Finally! Highly recommend.

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

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.

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.

The product removed the stains in the toilet bowl Immediately with very little effort and lived up to the reviews as previously stated. May I say a job well done.

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

It works.

Great quality for the price. As described by seller.

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).
