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

I used other products while trying to remove mineral stains from the Hot Tub. I say trying because they didnt work. This stuff was effortless. Worked great.

I don’t often write reviews. Great Product

This product is awesome! I have been looking for something to clean the hard water spots for a while, especially in the water dispenser! It looks great! Super happy with this product! Love that is non toxic and eco friendly! Buy it!!!

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.

This product did not work to remove water stains.

Its not every day I rate a 5 on all levels, but this product performed exactly as described and has exceeded my expectations for a cleaning product. I live in Florida, hard water and lime stains are in abundance. Ive tried all the popular brands, but nothing has worked as effortlessly and effectively as this. I used it on my shower glass and just for the heck of it tried it on my smooth shower tiles, both came clean with no effort. Wipe it on and wipe/rinse off.

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.

i used it on heavily stained hard water stain glass...it worked very well and my shower glass door looks brand new.

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