Bioclean Hard Water Stain Remover 20.3 oz

This stuff is AMAZING. We have well water, so hard water stains are a constant battle. I’ve tried at least 10 different products on the glass shower door edges, faucet, and handles—and nothing worked. The fumes were awful, and I was beyond frustrated. I finally decided to give this a try, and wow. Just wear gloves and use a Scrub Daddy—a little goes a long way. It works like magic. You can actually feel the buildup coming off as you wipe, and there’s barely any scrubbing needed. The hard water stains completely disappeared, even on the faucet and handles. I went a little wild and used it on the granite behind the faucet too—gone there as well! Then I did the entire shower glass, and now it’s so clean it doesn’t even steam up anymore. I hesitated to spend $18, but I’m so glad I did. It’s absolutely worth every penny.

I almost don’t believe how good this product is... Bioclean Hard Water Stain Remover is nothing short of miraculous! I own a small, professional, eco-friendly cleaning company. So, I’ve tried basically every cleaner under the sun—vinegar mixes, abrasive powders, and even harsh chemical sprays on occasion. But NOTHING even touched the stubborn hard water stains on my OWN shower glass and faucets. But this stuff? It erased years of buildup like it was nothing. I’m talking stains I had fully accepted as permanent...gone. Glass that used to look cloudy and etched now looks brand new. Even my stainless steel fixtures look polished and restored. I LITERALLY kept saying “What is THIS?!” the whole time I was cleaning. And the best part? It’s eco-friendly. WHAT??? I still can’t wrap my head around how something this effective isn’t full of terrifying fumes or harsh chemicals. There’s no overwhelming smell, no burning hands, no need to open all the windows and pray. A tiny bit goes a long way, and the results are instant. It’s one of those rare products that actually exceeds the hype. If you’re dealing with stubborn hard water stains, soap scum, or mineral buildup, do yourself a favor and get this. It’s basically magic in a bottle. One things for sure... I’m a customer for life!

Great remover. I tried several products to take calcium deposits off window glass. This product is the only one that worked. Easy to use. No scrubbing.

I bought this product for the hard water stains forming on my granite counter around the faucet area. It really didn't do much because I had to scrub and use a stainless steel wire sponge to remove most of the stains. The product is in a mint green paste which is safe to use and left my counter shiny without any marks. I also used this product on my stainless steel kitchen sink, the inside of my washing machine, and the bathroom which worked really well. It eliminated all the water stains and left it shiny, clean and it was easy to clean off. I will definitely continue to using this product.

I cannot overstate how good this product is. I have terrible hard water spots on my shower doors since I bought my house 9 months ago. I have tried every product you can think of and a few home recipes- nothing made a dent. I saw an ad for this on social media and figured it was worth a shot. It is not a wipe and gone. But with a little elbow grease it gets the job done. I worked in small areas, sometimes let it sit for a few minutes before scrubbing, and in a few areas used an electric scrubber to get more stubborn spots. I still have a shadow of spots in a couple of places that I will continue to work on but I had to write this review. It also has a pleasant smell - my husband compared it to toothpaste but I think it’s a little more reminiscent of Icy Hot. A little does go a long way I’m actually excited to use it on my other shower. I had my husband pose the same in both photos so you can truly see how clear it is.

Didn’t work for my shower glass stains. I’ve tried about everything. Vinegar, bleach, soap, tilex mold and mildew. Nothing works for this stuff. I think it’s just how it is. Nothing will get rid of it completely. I put it on and scrubbed with a hard bristle brush and then let it sit for about 10 minutes. I guess I will keep trying more and more. It lightened it up a bit but still there.

I purchased this product thinking it would work ok but not the way I wanted. You know how it is, all these companies brag about how their product removes stains and when we try it, it only works like 80-90% effective. Folks, that has changed! I placed a small amount onto a damp sponge, and began wiping the tub around drain (green chlorine residue) - not scrub, I wiped in a circular motion and the green residue came RIGHT OFF - INSTANTLY- if you want 100% results for removing sink, toilet and tub residue stains, buy this product and use it - and guess what else, you’ll also find you won’t have to wear out your arms scrubbing and scrubbing 🧽! The best cleaning product I’ve EVER used!

I bought this today and was really excited to try it, so of course I went straight to cleaning. It definitely removes a lot of buildup and stains, but if you expect your faucet or sink to look brand new immediately — it won’t. I can still see some spots, so I’ll try again tomorrow and maybe a second cleaning will finish the job. Even so, I really like the results so far. One thing I want to mention — the label shows a mom holding a baby, but after reading more online, this is not something you should use around children. The ingredients are not fully eco-friendly and the smell is strong. I recommend using gloves, and even a mask if you’re sensitive to scents. Overall, it works well and removes a lot, but it’s not a miracle cleaner in one swipe and it’s definitely not “baby safe” like the picture suggests.
