Bio Clean: Eco Friendly Hard Water Stain Remover (40oz Large). Pack of 2

I’ve tried many soap scum removers for my glass bathroom doors until I found this great product. Its price is higher than regular cleaners but it’s worth every penny not only because it works great to remove stains but also because it’s thick and you only need a little bit. I highly recommend.

This stuff is great removes hard water stains . Use a dry clothes and scrub and wash after with water and leaves it like new. Tryed so many other brands that didn't work but this really works compared to so many other brands I've tried . Would definitely buy again.

I have tried so many different products and home remedies and didn’t have a lot of hope for this one but ChatGPT strongly recommended it. I had never heard of it before but this is without a doubt the GREATEST product on the market for removing hard water stains from glass showers. Only used 1/4 of the bottle. You rub it on like a car wax and buff it off. Glass is like new. I am BLOWN AWAY. ❤️ Thank you Bio Clean.

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.

I have tried what feels like everything. Vinegar, erasers, pink goop, ultra fine wool, bleach products, etc. This stuff is crazy good! I wore rubber gloves and scrubbed this area with a kitchen scrub sponge for approx 1 min before rinsing off. It smells like wintergreen mint and I did not find it overpowering and did not vent.

Overall this product has a nice scent, it is versatile, however would be better suited in a tub style container. As the product is used, you have to hit the bottom and squeeze the bottle to get the product onto your towel, it comes out in a blob so you have to fold the towel onto the product to avoid it falling off the cloth and onto other surfaces. It will discolor area rugs or bath mats requiring them to be laundered. I also noticed it seems to melt or damage the microfiber dusters and I had to discard my duster. It got onto my duster from where the product drooped down over the side of the bottle and was in my tool bag. I did not give it a higher rating, due to the useability of the product, I clean homes professionally and need products that help me to be efficient.

This really works!!!!! Great value for money !!!

Great product.
