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

Glass cleaning and bathroom shower doors are shining.

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!!!

Incredible. Removed hard water stains from windows without even rinsing in minutes. Vinegar wouldn’t touch these stains either.

I used this to remove hard water stains on shower doors. I removed the doors and scrubbed with this this product. It removed almost all the hard water stains and did not damage or scratch the shower doors. Needed some elbow grease, but you can see the difference. We have tried so many products and home made remedies and nothing worked. I will buy this cleaner over and over.

Moved into an apartment with already prominent hard water stains and tried lots of different hard water cleansers, sprays, and scrubs to try to improve it. Was recommended this by an Instagram Reel I think and I’ll be continuing to buy and use this product! I used a soft dish wand sponge and this product to gently scrub in circles on my glass doors. I didn’t use a lot of pressure, just enough to spread and scrub a bit. When I rinsed, I was so shocked to see that my glass was transparent (when wet). That had never happened, it would always fog up and show the water marks. While dry, you can still faintly see the marks, but I think that’s just due to my low pressure or just being the first time use. The improvement is so much that I’ll recommend this and continue to buy.

If youre questioning if you should try this or not... just add it to your cart now! We have hard water-we remodeled our bathroom Im 2016 and now only 6.5 years later our sink was looking so grungy because of it. Ive tried product after product with no results. I saw the reviews for this and it was on sale so I thought what the heck Ill try one more thing and Im glad I did. I posted pictures of the difference in our sink after using this product and 20 minutes of minor elbow grease. Amazing! Im so pleased!

I moved into a new place and the hardware was grimy that even bleach and peroxide and dawn dish soap wasn’t working to remove the grime on my shower head and faucet and the stains in the tub. This, however, actually worked! Highly recommend this. Also it smells minty, which is a nice touch. I would buy this again in a big bottle.

I bought this for our one piece fiberglass shower and glass doors. Only tested it on one glass door. It took quite a bit of elbow grease and a scrubby green kitchen type sponge. It does make the glass better (my door is not etched or glazed, so I can’t vouch for those type of doors) than it was, but I think it needs more than one application. In my case, my shower has a lot of build up, and I have not found a good product or method over the past 15 years in this house, so I’ll update after I try it on the whole shower and a couple of times. I did not get a tool to scrub it, as I assumed the basic green sponge would do the trick, plus I don’t want to scratch the fiberglass of my shower. I have a bristles scrub brush which I’m going to try on the fiberglass next. It rinses off easy, so it’s good. It doesn’t have a strong cleaner smell, imho, so that was not overwhelming for me. It depends how sensitive you are. I just hopped in the shower before taking a shower, and tried to work it on the surface. As I said, a lot of elbow grease, so give you some time to work it in. It’s a creamy consistency, not really gritty, so it stay where you put it mostly. I wonder if after scrubbing, I could leave it on for a bit? I think it does better than any CLR, limeaway, scrubbing bubbles, etc etc product, so it’s worth a try. Once I get to work it through and clean, I will post update with before and after photos. I also read about using jet dry on the surface to keep water from forming scaling again, like on your dishes. So that’s something to try too next.

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.

I had tried various methods to remove water spots from our shower glass over the last year with no success. I was somewhat skeptical of whether this one would work as a result. I used as directed and ended up with spotless glass that looked like the day we had the shower installed. Im completely sold and would highly recommend.
