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

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.

Seriously, just buy this. I tried the lemon and baking soda, the vinegar on paper towels for 60 minutes, the dawn with baking soda and vinegar. NONE of it worked. Found this product. Worked beautiful and easy as I would expect. Stubborn areas took a little work. All other areas came off beautifully. The rinse process washed it off and a quick dry and it’s good as NEW. Most products don’t work as advertised, this does. My shower is 2 sided glass. 9’ high x 7’ wide. 2 years of use and had quite a few areas with water stains 6’ and below. Keeping this handy and using for other things already. Great job bio-clean. Ordering the big pack now.

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!

Hard water stains that have built up against the shower walls the past couple of years completely came off like butter!!

Lo use y la verdad me sorprendio lo bueno que es, había tratando mucho las puertas de los baños y no habia podido remover el javon o agua que tenia, no lo pude remover todo a la mismas vez, pero si funciona..

I have tried abrasive cleaners, homemade remedies, scrubbed until I was ready to set fire to the sponge, and with a knowing, yeah, right, I ordered this product truly as a last resort. I cynically tried it, expecting nothing or an insignificant change, and much to my absolute shock and delight - IT WORKS !!!! IT IS A MIRACLE !!!!! How often does that happen ???!!!!! I hate the look of hard water stains in my very clean house and this product has me smiling ear to ear. Everything looks so sparking clean and tidy. Buy it, you will NOT regret it. FABULOUS PRODUCT !!!!! THANK YOU !!!! THANK YOU !!!!

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

I purchased a home in which every toilet had prominent mineral stains inside the bowl. I tried multiple products that said they could remove the rings, but none even touched them. I saw this product advertised on Amazon, read the reviews, so I bought it figuring it couldn’t do any worse than everything else I’d tried. I let the water out of each toilet bowl by turning off the water inflow valve and flushing, then squeezed some Bioclean directly onto the stain. I used a toilet brush, scrubbed it in sections quite vigorously, and - - Voila! The stain was completely gone! I did this in all of our toilets and each was like new! I also used it to remove some stubborn rust stains from a bathtub in which nothing else I had tried worked. I did have to use a brush and elbow grease, but every bit came off. This product is truly amazing!

I cant tell you how great this stuff works. You do have to use a little elbow grease, but not much. I have had FL hard water stains on this shower door glass for quite some time. This stuff made it like it was just newly installed. It also took stains off other bathroom fixtures that were brushed nickel. Will take paint off so dont recommend that anything thats painted.

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.
