I dont usually submit reviews, but this product deserves one! Its hard to hold/use, but it worked miracles on the brownish red hard water stains on my toilet. Sent one to my dad and it worked perfectly to remove rust stains from his toilet. Awesome product!

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!!

I had a bad stain in the toilet from hard water and the rust it caused in the tank. This little tool took care of the biggest part of the stain almost immediately. The only problem: this is a block of pumice and is hard to get under the rim of the toilet bowl. But Im not going to return it and I will order another.

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

The product completely removed an old hard-water ring in the toilet bowl in about 15 minutes and it did not scratch the porcelain, just as advertised.
