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

It works.

Omg it’s really work I try every thing but this one is great!!!!

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 used this today for the first time. It worked like a charm!!

Had water spots on new shower fixture. Used EVERYTHING with no results. This worked in an instant with not scrubbing....and the best thing is it smells YUMMY! Not toxic. Read what it works on and it is true!

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.

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.

Glass cleaning and bathroom shower doors are shining.

Its not every day I rate a 5 on all levels, but this product performed exactly as described and has exceeded my expectations for a cleaning product. I live in Florida, hard water and lime stains are in abundance. Ive tried all the popular brands, but nothing has worked as effortlessly and effectively as this. I used it on my shower glass and just for the heck of it tried it on my smooth shower tiles, both came clean with no effort. Wipe it on and wipe/rinse off.

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