Giant Lion Hard Off+ Hard Water Stain and Spot Remover For Bathroom, Shower Doors, Glass, Tile and Metal 16oz

Lemme start with that I wish I had taken a before picture because this product literally took off YEARS of hard water buildup on my window because of an ill-placed water sprinkler. When I say this window was cloudy, it was literally a glass panel of white blur. Im glad I found this product cause it’s easy to use, works really fast and actually gets the job done. I was scared when the directions mentioned having to resort to scrubbing if the stains persist but I’m so glad I didn’t have to. Just with the spray and a sponge, my window was crystal clear again. The scent isn’t too bad, a bit citrusy, but if the wind so happens to blow towards you: hold your breath and close your eyes. (Can you guess how my experience went?) Disregarding the winds being against me, 10/10, 5 stars ⭐️, would definitely recommend and purchase again.

Is not as effective removing hard water stains on glass as advertised.

Worked beautifully to remove stubborn hard water stains on our windows

I clean professionally and needed a product to take off hard water stains. This product promised to do just that. I tried it on several clients homes and it did not work at all. Made no difference at all. Just made extra work for me. It is easy to use. Just spray on and rinse off entirely. As it can damage surfaces. I was really hoping it would work and make my jobs easier but it did not.

Did not worked as expected although it dissolved most of the hard water spot after several cleaning. I will give it a 6 out of 10.

People, I tried several bathrooms cleaning stuff locally but none seems to work on my bathroom shower floor soap scum or lime deposit. I saw this on Amazon with good reviews I read of course so what the heck I said I get one and try. With my surprise this stuff really works and made all those stubborn stains issues disappear. Make sure to follow instructions like apply this on dry surfaces 30 seconds or more wait. I did second application to make sure all stains are gone and it did. My only regret is didn’t take picture before. Highly recommend this product.

We live where there is very hard water. I've tried everything, including a harsh acid chemical, which worked, but kind of not the safest thing to use. So I gave this stuff a shot. And I have to say, I'm extremely impressed. After remodeling our shower and putting in white subway tiles, I wanted to keep that brand new look. I had let the water spots build up over the past several months and this stuff removed them after only a few seconds. I did a couple applications because I had so much build up. But wow! My tiles are shiny and brand new looking again. And it shined up my shower faucet as well. Highly recommended!

Works well on hard water deposits!
