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

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

It was like magic on the ease factor and using very little to go a long way. I literally did no scrubbing for tough water stains on my 3 sided glass shower walls and door. What was to start a test, ended up being the whole thing in 15 mins. I did use a razor blade scraper for one section and not on another, to compare and they were virtually the same results in the same amount of time. There are not many products that will “wow” me but with the combination of low Oder, the power and ease, and a protective coating like Rain X left behind (that I know will work much longer than the store bought brands like CLR, Kaboom that I typically use). I am a believer of this product.

I’m so impressed, I gave a bottle to my house cleaner to use for her other clients. The cleaner actually lasts for the 3 months, as claimed!

Not sure if works or what have to play a bit with it to see

It’s okay. It didn’t really remove the hard water stains from my shower as well as I’d like. The residue was still evident after rinsing several times. Would I return it though? No. Would I buy it again? Also no.

I wish I had taken a before and after photo! Our old shower door just never seemed to get clean. I tried lots of different products claiming to remove hard water buildup and/or soap scum. This REALLY worked. And it did not require a lot of elbow grease. Seriously, its magical. As a bonus, it didnt smell harsh at all. It smelled just like Pepto Bismol... slightly minty. I called my husband upstairs like 10 different times to be like Wow! Look at it! Our house is 25 years old and in the 4 years that we lived there, the shower door has been unsightly no matter what cleaner I tried. Now it looks like new!

This Bio Hard Water cleaner is amazing! I used to not like to clean windows but not I will even clean yours!!! This product is great for hard water removal! Wipe on and wipe right off!!! No streaks… nothing but clean shiny windows!!

Love using this product for cleaning shower glass doors. Gets the hard water stains off first try. Its my go to for my cleaning business.

Works well on stainless steel appliances.

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!!!
