  • Works for me, that's what counts
This isn't the classic acidic cleanser that foams and dissolves hard water deposits. Those are great when they work, but whatever is in my water seems pretty resistant to those cleaners. Bio Clean maybe takes a little more work, but it does a better job of cleaning the hard water deposits in my house than those other cleaners. ... show more

  • Excellent Hard Water Stain Remover
This cleaner works very well for removing hard water stains and mineral buildup. It’s easy to use and the results are noticeable after just one application. It helps restore surfaces and leaves them looking clean and fresh. I like that it works on different areas like sinks, showers, and tiles. Overall, a very effective cleaning product and a great addition to my cleaning supplies. ... show more

  • It works; but there's a reason why it works better than most.........
After reading many product reviews, before I ordered this product, it became apparent, once I tried it, why some people are complaining it puts tiny scratches in their glass or to not use it on Plexiglass (per instructions on bottle). The reason is this calcium and scale remover contains a very fine polishing agent (Similar to the way Ajax or "Soft Scrub" type products work). However, to note the polishing compound in this is very, very fine, much finer than Ajax or Soft scrub type cleaning products. It's almost non register-able when you rub it between your fingers. Think "Toothpaste" type polish level. The consistency of the product is too thick to put in a spray bottle; consistency is similar to "Gogurt" or more liquid type yogurt. Not too thick, not too watery. So, does it work? Yes, it does. We have a stainless steel dish drying rack. Over time, it does get some scale in it from dishes dripping water. We live in California where our local water sources are pretty "hard water", so scale is an issue. Once I put this on the rack you could see it start to dissolve the calcium instantly. Upon using it more like a polishing compound (Rubbing it in well and working it into the steel) it dissolved the scale with ease and did leave a nice finished/polished look. We also used it on the shower doors and on the shower hardware. It does work and it works well. There is no magic to it, like anything else you have to put a little effort into play but the results are well worth it. But, to note, since it does have a fine polishing agent you do want to be careful and not use it on plastic shower doors, or glass you value as "Optical". But, then again, if you have plexiglass shower doors that are that "bad" chances are they're past hurting anyway so I personally wouldn't think it would do them any worse. I don't think I would use this on my auto glass as I wouldn't want the run off or product having any chance of getting on the paint. ... show more

  • Works on plastic shower floor and sink rings Works on plastic shower floor and sink rings
Product really works! I had a fiberglass acrylic hard water stained shower floor that I tried comet, Brillo pads, baking soda, vinegar, boiled water, easy off oven cleaner just about every YouTube hack I could find and nothing removed the stain even after overnight vinegar and oven cleaner attempts. I ended up using a razor but later I found a more gentle paint scraper from Dollar tree that worked. I found this product through a Reddit cleaning suggestion and decided to give it a shot. It arrived in tact and it has a mild fresh scent with the consistency of toothpaste. For my bathroom sink I found an old toothbrush could easily remove the ring with vigorous scrubbing. For the kitchen sink, I found a palm brush that worked best. For the shower floor a stiff bristle brush worked. I originally wanted to only buy one bottle but the two pack was cheaper. Glad I got the extra bottle because it really works. I recommend wearing goggles or glasses to protect your eyes because it does require vigorous scrubbing but works way better than pink stuff which I also bought and tried out. ... show more
