Powerstone Pumice Stone Toilet Bowl Cleaner with Handle (1-pack) - A Reliable and Harmless Solution for Cleaning Limescale Deposits, Mildew & Hard Water Stains on Toilets, Grills, Tiles, Grout & Pools

The flapper in my toilet tank is loose, which results in a near constant stream of hard water and some ugly stains that chlorox gel didn’t even make a dent in. I used this pumice stick and it didn’t even take much pressure to see immediate results. Now my bowl is a clean and white as it should be. Great little product! Highly recommend

I wish Id taken a picture. I really didnt expect this to work! Ive tried toilet bowl cleaner, Borax and vinegar, CLR, baking soda and vinegar...and nothing worked..until this! This product was easy, amazing and effective. Hard water stains are gone on all 4 of our toilets. Now I wont be embarrassed to have guests use our bathrooms. Im just astonished at how quickly and easily this worked. I would definitely recommend trying this!

This product is great. It tool the yellow ring around my toilet out. My toilet looks new

I was thoroughly impressed with how well these things work. Ive had buildup on one of my toilets that even 0000 grade steel wool was ineffective on; 5-10 minutes with this stone has that toilet looking very good.

I was surprised at how easy it was to remove hard water stains from the toilet. With five minutes and some elbow grease, this pumice stone really improved the look of my toilet. Ive used it once and theres still quite a bit of it left to use in the future. When it does run out, I will definitely buy this again!

This does clean hard water and rust very well. I cannot speak to whether it is damaging my porcelain surface though. I think of it like an exfoliant with its little micro scrubbing grit.

It really works .

Absolute magic....after using every cleanser out there to remove hard water rings, this product did the trick, literally took 5 minutes to clean two toilets. Thank you!

This one does much better than others Ive had, mainly due to the nice handle which eliminates the need for gloves most of the time. Love the case, too!

I wish I had taken before and after pics of my toilet!!! It’s unreal the difference this makes!!! Absolutely The Best!!!! Stains are gone after trying everything else!!
