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

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.

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

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

I have frosted shower doors that no matter what product I used would not look clean. I saw this on Buzzfeed and read the reviews so decided to try it. It took some muscle but I got the doors and the shower stall looking practically brand new. I definitely recommend trying.

I don’t do reviews much, but I had to for this product! Best thing ever for hard water stains. We have a big window in our master shower at the property we just bought and we thought it will need replacing because looked like previous owners never cleaned it. 2 window companies came out and said it will cost us about $700, well before doing the order I decided to try this and OMG!! With a little elbow grease it worked like a charm ! On the picture on the left you see before and on the right after.

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..

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!!!

If you have hard water stains buy this. Our water is th worst. Leaving a hard white film nothing would take off. With this it’s a easy scrub and gone! My daughter bought a bottle and the granite she thought was ruined came out beautiful. Just try it. What have you got to lose?

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!

Sparkling cleaned fiberglass shower stall. So much hard water buildup over the years. Scrubbed off and rinsed within 10 minutes. Amazing product. Soooo sorry no before and after pics. Amazing miracle product!!!
