Bio Clean Hard Water Stain Remover 40 oz. (20.3 oz.)

I used this to remove hard water stains on shower doors. I removed the doors and scrubbed with this this product. It removed almost all the hard water stains and did not damage or scratch the shower doors. Needed some elbow grease, but you can see the difference. We have tried so many products and home made remedies and nothing worked. I will buy this cleaner over and over.

You can scrub until your arm falls off but if you’re not using an effective product, it doesn’t matter. So I tried this stuff and I got the ugly water stains out of the toilet. Easily! Finally! Highly recommend.

i used it on heavily stained hard water stain glass...it worked very well and my shower glass door looks brand new.

Its not every day I rate a 5 on all levels, but this product performed exactly as described and has exceeded my expectations for a cleaning product. I live in Florida, hard water and lime stains are in abundance. Ive tried all the popular brands, but nothing has worked as effortlessly and effectively as this. I used it on my shower glass and just for the heck of it tried it on my smooth shower tiles, both came clean with no effort. Wipe it on and wipe/rinse off.

It doesn’t clean as quickly as I expected it to. I do like the smell

I still can not get the hard water stains off the bathroom glass showers and I even use a drill with a sponge to try and do a better job, but it doesnt quite do the job. Disappointed, and not sure what to try next.

I really did not expect this product to be this amazing. It was just delivered and I thought I would give it a quick try on these heavily crusted windows. It goes on like a paste and polishes off easily. It removed ALL the calcium deposits within minutes. You also only need to use a small amount. You can see how badly stained the lower window was by comparing it to the one above that I have not cleaned yet. This is the best value for money I have found on Amazon.

Tried all the other tricks with vinegar, baking soda, lemon etc. This stuff is like a smooth green paste that is easy to work with. Like others say, you do have to do some rubbing before it starts to take the rough stains away. At first you feel and hear the roughness and then it slowly feels smooth. Then when you wipe it away you can’t believe it!! Super stoked!! Did a 10 yr old shower glass enclosure that I was about to pay to be replaced. It worked fine for me with paper towels or sponge. I had an issue with glass scratching when I tried a drill brush attachment so I stopped using it and went back to paper towels and sponge.

I barely write reviews. My husband NEVER does. Our 12 year old French doors are constantly hit with hard water. I’ve tried everything to clean them (and I’m a clean freak so imagine how this has impacted me…) CLR, car detailing kits, commercial vinegar, water spot waxed and removers, bleach, tide, commercial windex, Spray and Forget, OUTDOOR windex—everything. Last night I lost my mind after spending 6 hours on them. I almost used steel Wool. It would have ruined the glass but I was about to call a company in to have these very expensive doors replaced. I ordered this in tears as my hands were cramping from scrubbing to now end and no end in sight. Enter this gem. Wipe it on with a rag (wear gloves), let it sit for one minute, wipe in small circles and wipe off. This is ONE application! Just one. LOOK AT MY STINKIN DOORS GUYS! Common! SERIOUSLY?! I am blown away! Again, I tried everything for YEARS and it just got worse! How that was possible? Hard water (garden hose!). Again, look at the two panels on the top not done and the ones below it—5 minutes, one application! I’m going to use two applications (why not) and then try other things in the house! I’ve already ordered 4 more bottles to have on hand incase they don’t make them (Or raise the price)!

We have incredibly hard water and therefore impossibly he’s to remove water spots on everything. I have a fish tank and the water spots on the outside were driving me crazy. Windex didn’t help so I searched for hard water spots remover on Amazon and this came up. I tried it. OMG!!! My glass has never been more clear!!! And it cleans off so nicely without any residue or smudging!!!
