They work

I have never used pumice stone before. I have terrible hard water stains in my toilet. None of the commercial toilet cleaners work. I did a little research and came across the use of pumice stone for cleaning hard water stains. So I ordered this product. I wondered if it would work because it is a rectangle. No problem. The pumice stone wears down while in use and conforms to the shape of the bowl. Saturate with water and start rubbing. Wow! It removed every bit of that hard water ring. Great product.

Love how easy to use these are when it comes to removing hard water stains out the toilet that normal toilet cleaner and brush don’t get.

I use for toilets( hard water) and other hard to remove build up.

No joke, my toilets look brand new after using these! I had bad hard water stains on both of my toilets and after using these with a little bit of soft scrub they look spotless! Recommended these to my entire family and friends!

This has worked great on our shower door that had hard water spots. Just wet the stone really well and lightly scraped and the white hard water stains are gone.

Not sure if they’re supposed to disintegrate while cleaning but either way they get the job done!
