Powerstone Pumice Stone Toilet Bowl Cleaner with Handle (1-pack) - A Solution for Hard Water Stains on Toilets, Grills, Tiles, Grout & Pools

It really does work on the toughest hard water stains. Although I forgot to take before and after pictures, I can assure you it does work. It really is like magic. I used it for all my toilet bowls. However, couple of notices you should know before buying. 1. You need patience, especially if your toilet bowls have very old stains. It took me 30 minutes of constant grinding and used entire stick. 2. Do not push down on the stick aggressively, it will break in half and I had to use by hand. Cleaning power is incredible. I recommend this product.

I ordered two of these. They worked great on getting some stains out of my toilets. The house that I live in had stood empty for over 5 years when I moved in. The toilets were in rough shape. I had tried everything I could possibly think of before I found these pumice stones. My toilets looked brand new once I used the stones on the toilet bowls. Would highly recommend!

The stone worked great. We live in an area with very hard water and the stone totally removed the build up in no time. I will reorder this as soon as we need it.

Bought this because we had some brown water in our town after a water main break and it caused a dark ring around our toilet bowl and also staining at the bottom. I assume it happened so wuaickly because we already have very hard water and keeping toilet clean is something we need to stay viligent to keep clean. The staining became impossible to remove after trying many products, I looked for a pumice stone. This worked as expected, Inwas a little nervous it might damage the porcelain but working carefully it did not and I was able to remove the stained calcium buildup

We had a toilet with limescale and hard water stains that would not come out and we tried many cleaners. I was skeptical that this stone would work but figured I would give it a try. This removed the stains on the first try. I had to put some elbow energy behind it and the stone does wear away as it cleans but it removed every single stain. The bowl looked new again. I have used the stone twice now and it was worth the money!

Amazing! The stain in the toilet was gone in minutes!

While the item does work, it was disastrous mess when taking the plastic off. Fine white pieces fell all over the place. Also, I was hoping to use this in my toilet, but it is not reached as far as it needs or is it shaped correctly for the job.

Had a stubborn ring around the toilet that nothing would remove. Ten minutes with this Pumice Stone and the toilet looks brand new.
