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

Best product I’ve found for taking hard water stains off our shower doors! I used a scrub brush and it took the hard water stains right off. We’ve lived in our house for two years and used so many products. Nothing has worked for us. This stuff is MAGIC! 10/10

Best product for soap scum,shower glass cleaning,fixtures,sinks,tubs,tile.Have used so many products this is by far the best! Let products sit for a few minutes and rub off with light scrubbing,just wipes away. Bought after reading reviews.No harsh scent.Wear gloves.Bought the double set but after 1 cleaning I will never need so much product.A small amount goes a long way.

Found a solution to get deodorant stains out of T-shirts, I put some of this on my shirts with a little baking soda and peroxide through them all into the washing machine and shirts I haven’t worn and had in a box to throw away or now hanging in my closet, and I am wearing them again! I did do some light scrubbing and allow them to soak. When I put them in the washing machine, I did the longest cycle I could with a pre-wash and permanent pro setting. Because I was not sure if the stains came out I hung everything to air dry I even had a couple black bras that were so stained. I was too embarrassed to wear them and they came out perfectly clean and no longer hard and crusty! This was my own test. I figured I was going to throw everything away anyway, so it was worth a shot.

Nice smell. Definitely helps to get hard water stains off glass shower doors. I had to repeat the process a few times.

I'm obsessed with this product! It smaells nice and works in loads of ways. I've used it on glass, stainless, crome and now antique brass. As a professional cleaner I've got it on autoship and recommend to friends and clients all the time.

I’m a cleaning lady and this is the first time I’ve tried this. It was recommended by another cleaning lady. I cannot speak highly enough about this product. It surpassed my expectations. Will always be in my cart from now on. Thank you for offering this incredible product

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.

Impressive performance. Cleans stubborn water stains alsmost instantly and with little effort.
