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

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

It worked on the metal parts of the shower system but worked partially on the glass shower doors

I’m so impressed, I gave a bottle to my house cleaner to use for her other clients. The cleaner actually lasts for the 3 months, as claimed!

We have very hard water where we live, and I had tried several things to remove the hard water spots from my glass shower door and side wall. The house is about 20 years old, though we have only been here 6 years, the previous tenants werent exactly meticulous about cleaning. Tilex, vinegar, etc., nothing worked. The vinegar works fine if you can soak an item, but spraying it on a vertical surface was just not effective. Finally tried this stuff, and my shower looks about 95% clear, with a bonus that the water sheets off of it nicely now. It does take some elbow grease, but I did it in stages over a couple days and it really wasnt that bad. I took off a star because it really didnt touch the gross yellow crusty build up at the base of the door that no amount of scrubbing or product of any kind seems to touch. I may try a scrub brush drill attachment if I can find one, and see if that works.

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

Ive tried dozens of different name brand products to clean mineral hard water deposits and soap scum, and its very very difficult. This product still requires elbo grease, but only a fraction of the effort required by most other products, including vinegar and/or baking soda. I think with regular use, this can become a very easy way of cleaning hard water deposits.

This stuff cleans my glass shower doors in minutes! I also use it on my windows for our house by the ocean … works great with the salt water marks on the windows!

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.

After trying a number of products and online instructions to remove soap scum from shower doors, I final found a product that works. I had 10 years of build up so needed 3 applications. I used 0000 steel wool to apply. I made circular motions and then used a sponge dipped in warm water to remove. I made a final pass with a lint free rag. This took off about 70% of the soap build up. I made 2 more applications and followed up with a foam glass cleaner. The glass on the shower door now looked new. Honestly, I had given up thinking nothing would work but this product did and I still have 1/2 bottle left for the future. I tried everything from vinegar to baking soda but nothing worked so happy I gave this a try. I doubt my wife would have had the same results for without the 0000 steel and coarse sponge dipped in hot water, I believe the results would not have been as good. The steel wool really gets this product into the soap scum and lifts it off the glass.

Love using this product for cleaning shower glass doors. Gets the hard water stains off first try. Its my go to for my cleaning business.
