I purchased this product after reading some reviews. It was a last ditch effort to use on a fish tank. There was a white residue dried all over a 75 gallon tank I had that hadn’t been used in the three years since I moved. I assume it was hard water stains or calcium or something of the sort on the glass walls. I HAVE TRIED MANY PRODUCTS TO GET THIS STUFF OFF AND NONE WORKED. I’ve scrubbed hard with different sponges and scouring pads and it was no use. Once the tank dried again the residue would be visible once again. So in comes this product. I used it with one of those slightly wet green scrub pads. I scrubbed in an oscillating motion and could feel what areas had a little more resistance so I scrubbed those a little more.. I then rinsed off the worked areas and let it dry to check if it worked. WELL I’M WRITING THIS REVIEW NOW BC IT ABSOLUTELY WORKED WONDERS ON MY TANK. The stains are completely gone. I’m so happy to have come across this product. Next use for it will be on my shower doors. I also used it on a glass coffee table with the same calcium/ hard water stains as the tank and it came out great too. Best part it says it’s non toxic so I was more at ease using it on my tank glass. Even though I’m still gonna run the filter for a while without any live things in the tank just to play it safe. But I highly recommend this product!!!

This is my first review on amazon, I have purchased many products but never before did I feel like I really had to write a review. I have tried for weeks to get rid of some very tough hard water stains on my glass shower panel. They had been there for 3 years while my apartment was rented and never cleaned... I have tried just about everything from toothpaste, to vinegar, to different types of chemical products. After many hours and sore elbows and a horrible vinegar smell on my last attempt which remained in the bathroom for days, I was just about to give up... The result was almost non existent. Until I found this product... PURE MAGIC!!! The non-toxicity of the product is definitely a plus, it doesn't smell bad and doesn't sting your lungs like some hard chemicals do... Its biodegradability is a plus! I fell better knowing I'm not dumping some more toxic chemicals down the drain... But most importantly, it works!!! After 10mins work it has removed 90% of the hard water stains that simply would not come off!! Conclusion, extremely highly recommended! Worth every cent! I just wish I could rate it 6 stars!!!

I can't say enough about this product. we bought an older house and are in the process of remodeling it. The shower doors had about 30 years of water buildup. I wish I had taken a before pic but I have attached an after pic. before you could not see the inside of the tub due to the cloud on the doors. we tried all kinds of products and home remedies with no luck. I used about a tablespoon with a dry light scouring pad and I can't believe how much it took off with a little bit of rubbing. We used maybe a 1/4 of a cup total on both doors and they look great. I also have Drexel sinks with the cast iron knobs we used it on those also with amazing results. We also used it on the cast iron farm sink in the kitchen it was discolored with years of buildup and stains and it worked wonders on it also. my next task is to work on the glass block wall in the bathroom. I did a test on one cube and it seems to work I am sure it will look just as amazing as the doors. I would recommend this product to anyone.

I tried baking soda and vineger for toilet bowl ring, but didn't work. So I tried this product. It's really works. It removed stain in less then 5 mins.

I was happy with the way it cleaned up water stains on our granite counter top. The one thing to note is that this product does require a little rubbing for it to work. Its not a wipe on wipe off type of product. I used a soft cloth and polishing motion and worked just fine. Leaves the area like glass smooth. Not too much pressure, just let the motion do the work. Wanted to make sure it was safe and so far looks great after 2 weeks. This product seems to work by being a very fine abrasive. Doesn't seem to do its work by chemical means so no real strong smell, almost like pepto bismol smell. If you have a large area I would suggest getting some time of powered tool to save time and effort.

I've tried everything to get the stains out of my tub and nothing has come close to working as well as this! Our house is old and has hard water from a well. We've been trying to get this tub to look better sense we bought our house, two years ago. My husband and I were considering replacing our tub because it looked so bad, but this made our tub look like new! The smell is pleasant and I feel more comfortable using non-toxic cleaning products, like this! I do want to mention that we used a cleaning brush drill attachment and it worked incredibly well together to finally get our tub looking clean! Be sure to get a brush attachment with this and you won't be dissapointed!

Works flawlessly to remove hard water spots on car; and easy to use (just squeeze the plastic bottle and apply the green lotion-like substance to a micro-fiber cloth and scrub the area for like 2 seconds, and then the hard water spots should be completely removed). To be safe, I rinse the area with water right after, but I don't think you need to do it. Before this product, I bought "3D Auto Detailing Products Eraser Water Spot Remover 16 Oz" but it was horrible and damaged my car; instructions were difficult too because this other product needed you to apply and then wait for like a minute before rinsing it off; otherwise, the acid will destroy car paint and stain windows. I highly suggest "Bio CLean: Eco friendly hard water stain remover." I only used like 1/4 of the bottle to remove all of the stains all over my car's exterior. The biggest plus is that the product is super safe to handle by human hand.

Amazing product!!! This is the absolute 1st time I have written a review for Amazon...and I shop ALOT! I have been looking for something to get the hard water spots off of my shower door and this did the trick!! I've used it on all my bathroom fixtures and they are sparkling. It makes me want to keep cleaning it works that well. It's a plus that there are no fumes and it's safe to use without gloves! Product actually smells really good..like toothpaste. I've already told all my family about it! Will definite buy again. Thank you!!

This stuff works well and has a pleasant wintergreen scent. I'm using it to tackle my bath tub and shower area, so I'm recommending that it is used with a non-scratching, electric rotating device. I'm using the Black and Decker PKS160 hand-held Power Scrubber. It's still a lot of work, but absolutely nothing had worked up until now.
