BIO-CLEAN 40 oz. (2) Hard Water Stain Remover combo PLUS Magic Cloth

I've tried soooo many things to remove the hard water stains from our shower door and nothing has worked. After reading tons of reviews I finally tried Bio-Clean and it absolutely does work! As others have said, you do have to scrub a bit especially if the spots have been there awhile.Once the spots are gone, I've been using once a month or so to keep it sparkling. Also works well for granite dulled by hard water. 5 stars!!!

My husband bought this to clean & polish the tops of the pontoons on our boat. He’d seen a guy use this online. After he rubbed some on the first small spot, it was SUCH a great, shiny clean! I looked at all the instructions & realized it’s designed for use in the home, kitchen, bath, etc. We have a natural stone bathroom counter & porcelain sink that’s all spotted up with hard water deposits. I know you’re supposed to be careful with the natural stone, but nothing I’ve tried works. I decided to risk it with this because otherwise it’s vinegar, which I know is bad for the stone. This stuff worked GREAT! It doesn’t appear to have removed the shiny protectant surface. There were so many spots in the sink, that it took some scrubbing- but with regular use, I should be able to keep the sink and counter looking new again!

Works great on hard water stains & cleans hard water spots on faucets very well! Also cleans the older cast iron & ceramic sinks very well! Always have on hand in my cleaning caddy!

We had a toilet that was hard to get "clean." I removed/plunged as much water as I could from the bowl and waited for the sides to dry off a bit. I applied the product and scrubbed it with a toilet brush to coat all the surface and let it sit. Came back and applied a little more, scrubbed a little and waited, then scrubbed more... The ring that wouldn't clean away before vanished. Used it also on 2 sinks and countertop and a shower door especially with the included cloth and you could the grippiness of the resides in the surfaces wipe away until the cloth glided much more smoothly over the surface. Time and patience on a toilet bowl does most of the elbow grease for you. It also smells good.

I had read some reviews online, but I have an entire cabinet of things with great reviews that did nothing for me. I bought this and one of the rotary brushes. The day that it came I thought I would try it on a little section and see if it did anything. Well, OMG! The little spot I tried came out SPARKLING CLEAN, so I kept going. Within 1/2 an hour my shower looked brand new! I will say that the rotary brush probably helped with my efficiency, but I honestly could not believe that I finally found a product that works and doesn't smell like death. It kind of smells like toothpaste. By the time an hour had passed I had finished sparkling up my shower, two bathtubs, two shower heads, five faucets, five sinks and two toilets. Really, just wow! I will buy this product forever!

We’ve been using this cleanser for years. Works as advertised. It’s our go-to for easily removing burnt residue from stove and pans. Works equally well in sink and other surfaces without scratching.

Perfect on glass showers

The product smells good and it's great for cleaning but not for stainless steel. This will mess up your appliances
