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

After trying a number of products and online instructions to remove soap scum from shower doors, I final found a product that works. I had 10 years of build up so needed 3 applications. I used 0000 steel wool to apply. I made circular motions and then used a sponge dipped in warm water to remove. I made a final pass with a lint free rag. This took off about 70% of the soap build up. I made 2 more applications and followed up with a foam glass cleaner. The glass on the shower door now looked new. Honestly, I had given up thinking nothing would work but this product did and I still have 1/2 bottle left for the future. I tried everything from vinegar to baking soda but nothing worked so happy I gave this a try. I doubt my wife would have had the same results for without the 0000 steel and coarse sponge dipped in hot water, I believe the results would not have been as good. The steel wool really gets this product into the soap scum and lifts it off the glass.

I purchased a home in which every toilet had prominent mineral stains inside the bowl. I tried multiple products that said they could remove the rings, but none even touched them. I saw this product advertised on Amazon, read the reviews, so I bought it figuring it couldn’t do any worse than everything else I’d tried. I let the water out of each toilet bowl by turning off the water inflow valve and flushing, then squeezed some Bioclean directly onto the stain. I used a toilet brush, scrubbed it in sections quite vigorously, and - - Voila! The stain was completely gone! I did this in all of our toilets and each was like new! I also used it to remove some stubborn rust stains from a bathtub in which nothing else I had tried worked. I did have to use a brush and elbow grease, but every bit came off. This product is truly amazing!

I don’t often write reviews. Great Product

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

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..

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 only thing that has taken the hard water stains off of my shower door! I’ve tried it all and this was almost instant with minimal elbow grease involved. Amazing product. Will be looking into the protectant they have to prevent these stains in the future.

OMGoodness! I have tried everything on the market for my 3 fiberglass tubs. Are you kidding me? We live in Northern IL where not only do we have a water softener, we also have a whole house water filtering system which helps, but cannot totally keep up with our extremely hard and orange well water. My husband usually has to spend all day first removing all hard water buildup, then actually using a car wax to polish our tubs. It has been our most hated project! I just tried this yesterday and WOWZA! I just applied with a damp cloth, let set 30-40 minutes, rinsed with hot water, dried with towel and....DONE! No gloves needed! Smells great. I wish I had discovered this miracle product sooner.

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.

Cleaned my shower door and the tray of ice/water In refrigerator door!!!!
