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

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

To say that my place has hard water is an understatement. Sometimes, it surprises me that the water doesnt just plop out in flakes or chunks. The large sheet of safety glass for my bathroom shower accumulates hard water deposits might fast. Like, should I fail to squeegee the water off of it for a couple of days, it looks like someone tried to tag it with spray paint. Rolled the dice on this product and WHAMMO!! Hard water stains were destroyed with one application (I still need to go back and do a bit of touch up). Not only that, but the scent is kind of fun - think Christmas peppermints mixed with Pepto. It worked so well, and with such a modest amount of product that I think I may ever try to clean the hard water stains off of the tile in the shower!

We have incredibly hard water and therefore impossibly he’s to remove water spots on everything. I have a fish tank and the water spots on the outside were driving me crazy. Windex didn’t help so I searched for hard water spots remover on Amazon and this came up. I tried it. OMG!!! My glass has never been more clear!!! And it cleans off so nicely without any residue or smudging!!!

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!

We live in an area with notoriously hard water. For years Ive juggled using a slew of various green cleaning products (including making my own) to take care of rust, hard water stains, and soap scum. Finally desperate and willing to bring out the big guns, I bought this along with another brand to see how they stack up against one another. This one was the winner in that it was MUCH more effective on its first use. The other stuff, while still more effective than the less expensive cleaners you can get at every local store, still needed multiple applications and tons of elbow grease to remove the stains (if it did at all). Both products have the same wintergreen(?) scent. The smell is much stronger with this one, though, and to a very unpleasant degree. I had the TASTE of the scent in my mouth for nearly a week after the last time I used it (and I wore gloves). It affected my taste, normal saliva production, and was altogether a bit disconcerting. But did I mention the stuff works? lol I guess Ill use a mask next time and see if that helps. I like that this cleaner is green in color b/c it helps ensure you arent missing any spots in application or in the scrub-off process. (The other one I tried was an almost translucent white.) One last thing: while I am praising this product for doing what it says, its not a miracle worker in that you slap it on, wait a few minutes, wipe, and your bath tub or shower is sparkling like it just came out of the showroom. You still have to scrub (and then rinse and then wipe dry). But its therapeutic for me to scrub it and IM SO HAPPY that years of build-up are finally coming off. I will definitely buy more but just figure out a better ventilation situation if possible.

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

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

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 !!!!

Great product ... you need to give it a try!

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.
