Giant Lion Hard Off+ Hard Water Stain Remover for Shower Glass & Tile, 16oz

This was exactly as advertised. We have VERY hard water and this cut through the spots like a hot knife through butter. Lite spots only needed to be wiped off with a terry cloth rag. The heaviest spots took a slight scrub with a new scotch pad. I have already ordered two more bottles.

I live in an area that has extremely hard water. Our windows were stained from the back splash from the sprinklers. Once I was able to fix the sprinklers I had to take care of the windows. I tried everything and nothing worked. So I thought I would try this product. It does not remove the stains right away. You have to follow the directions - let it sit for a few minutes. You may have to add a little elbow grease - but it worked and our windows look great!

Did the glass shower doors. Came clean. I recommend.

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.

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.

The best I have used

I have a newly built shower and we just moved in our new construction home the end of January. While this product does clean and shine the surface, it did not remove the water marks from my shower tile as hoped. The search continues.

Odorless and really works for stains that stayed for years.

Doesn’t work as great as I would like for the price
