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 didn’t believe this took would work. I’ve tried EVERYTHING to erase my hard water stains. Unfortunately nothing worked but this! I have well water and a ring around my toilet frequently. This removed the hard water stain like a champ and did not scratch the toilet. Very happy. Don’t wait and purchase now!

This is by far the best cleaning tool for hard stains Ive ever used. Super easy, and hands down better than anything else available.

I live in florida and the water here is hard unless you have a water softer system to keep stain build up away. toilets get a deep black ring on the inside, this removed it. The stone wore out on the tip on first use, so I will see how long it last. I comes in a cute little storage case. It does do the job!

Works as promised. Toilet had black streaks that would not come off even after serious scrubbing. Took a couple times, but this thing finally got rid of the streaks.

This worked like magic!!

I bought this specifically for removing this stain from my toilet bowl but even after wearing down the corners of the stick to a rounded edge, the stain is still there. I got a refund though.

easy to hold, got rid of a lot, but not all of rht hardwater stains and build up. Appearance is improved.

I moved into a hard water area, high mineral in water. This worked like a charm! I almost Ed replaced 2 toilets until I found this. Highly recommend it. A little elbow workout but now I only have to do it 3/4 weeks.

This pumice device worked great on a toilet that we once considered unsalvageable. We actually tried sandpaper to no avail and had just about given up. It removed the water ring buildup completely. However, the instructions say to rub gently over a period of time but that ring only laughed at me rubbing gently. It was only removed by force and over considerable time. I took it section by section so my arm and determination didnt wear out but in the end the pumice and my efforts prevailed. I would suggest you use this product before it gets to my level of desperation.
