Water Stain REMVR 40OZ

This is the best window cleaner ever! For someone who only washes windows once a year, this product cut through the water spots instantly. I will buy more. Hope they make it in a spray bottle for smaller windows.

I use this to get the hard spots off my windows and it works well—doesn’t scratch— which is amazing. It has a wintergreen smell. I have bought this multiple times.

Admittedly, I'm not a house cleaner. I don't enjoy it. I procrastinate. We also have very hard water. My husband ripped out our entire master bathroom and I picked out these pretty glass sliding doors, instead of the tacky frosted ones we had from the prior owners. I assumed you kept glass clean with Windex. Ha! Not with hard water! Hard water drops WILL NOT WIPE CLEAN! Googling got me to a semi-decent product by Lysol. Yes, it did remove most of the water spots whenever I cleaned. The issue is it started to evaporate while I was still scrubbing with my scratchy surfaced sponge and since the entire door and panel was being scrubbed, you couldn't see what you were accomplishing. It looked like you scrubbed all of the surface, but when you sprayed the area down, there were patches of hard water spots that needed additional scrubbing. It was very frustrating! Somehow I found this Bio-clean product on Amazon. Ouch on that price! I got the bigger bottle to at least get a better value. This product works! I still used the same scratchy surfaced kitchen sponge for cleaning. I think one of the reasons that it works is that it's a cream. You wipe it on and it mostly stays on (with a tad bit of evaporation) until you can rinse it off so it can continue breaking down those mineral deposits. The product rinsed cleanly away using the shower nozzle. Instead of going over the rinsed glass with a microfiber cloth, Windex, and my tears to find missed patches of mineral deposits, I only used a dry microfiber cloth to wipe the glass dry instead of an additional glass cleaner. I promptly got on Amazon to leave this review & order more for fear that it'll no longer be available. The price? That brings a few tears. But personally, I will save Bio-clean for tough jobs only, such as the shower glass doors. My boys' shower / tub will get the regular cleaner. I won't waste it on regular cleaning jobs due to the cost. If the cost were to come down, it's definitely a product I'd use more widely across my home.

This stuff works so well. It gets off hard water stains with minimal effort. It smells a little minty almost. I love that it’s a natural product with no toxic fumes or residue. That being said, there is no warning on the bottle about needing gloves - in fact, pictured in the bottle is a woman using it with bare hands. I did the same. Two days later, the entire inside of my hands is peeling. Have you ever done one of those foot masks where your whole foot peels? It’s like that. So far, it’s just one layer, but it’s pretty intense. I have snake hands and a clean shower.

Love this product. No scrubbing. It took care long lasting water stains easily. Took before and after pics - they don’t do it justice.

Nope Didn't remove hard water stains on windows even with the help of a new razor blade or 0000 steel wool

This stuff does what it says it really cleaned the hard water stains off the shower glass door they look new. Only used a little bit for both doors worked great I would recommend this product! Also cleans shower tiles well!

This water stain remover works really well on stubborn hard water spots — it definitely made a difference for me. It takes some effort and scrubbing, but the results are solid once you put in the work. I’m giving it 4 stars because it’s effective, just not totally effortless. If you’ve got tough stains and don’t mind a little elbow grease, this is a great product to have on hand.
