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

Why that ring forms I do not know but this pumice stone gets I off without damaging the porcelain. The handle makes it easy to use without getting your hands in the toilet water. So glad it was recommended to me by m niece.

I have been looking for solution to all the toilet stains without use of chemicals, and this is it! Didnt cause any damage or scratch to the toilet surface at all.

Did the job !!

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.

I’m had a combination of stains in our toilets and this removed all the stains from all 4 toilets. It works great! Extremely happy with this power pumice stone!

Couldn’t be happier with this product. We’ve been trying to get a hard water ring out of our toilet for 2 years now. I’ve tried scrubbing it with EVERYTHING. Used this and it was gone within minutes. Insane. And that price!! Also love that it has a handle so you don’t have to put your hand close to toilet water! I also barely used any of it, so these will last me for a LONG time!

Finally the hard water lines are gone!

Excellent product ! Easy to use and works well

This will be my first 5 star review. I had mineral deposits in my toilet bowl that I had tried removing with many items including a pumice stone and nothing seemed to work. I purchased this item due to its’ positive reviews and they were right ! It worked great and without much effort on my part. This really works. The deposits were removed and I am no longer embarrassed by my toilet bowl. Worked great for me.

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.
