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

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.

I bought this along with a handheld Scrubber for my shower door. It works awesome!

This stuff actually works! And I like that it is Evo friendly , non - toxic and biodegradable! I had tried so much, and I will use nothing else now.

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.

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

Not a product that won’t require some effort on users part. BUT it does work! AND it won’t destroy the finish of your faucets like another product did to mine. You’ll have to do some scrubbing but it will remove scale build up. Sticking with it for now.

I have hard water stains on my shower door and walls.. this did not remove them

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.

Great quality for the price. As described by seller.
