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

Absolute magic....after using every cleanser out there to remove hard water rings, this product did the trick, literally took 5 minutes to clean two toilets. Thank you!

This product worked great and quickly. Removed the stubborn ring stain in a couple of minutes, worked better than I thought and comes with a plastic cover so it doesnt leak after use when placing it away. Would buy again.

Gets out the rust stains around my toilet bowl, only downside is that its not very comfortable to hold.

Excellent product ! Easy to use and works well

Did the job !!

Easy to use & cleans well as described.

I was thoroughly impressed with how well these things work. Ive had buildup on one of my toilets that even 0000 grade steel wool was ineffective on; 5-10 minutes with this stone has that toilet looking very good.

My house is very old and the toilet was badly stained. I wasn’t sure it was something that would even come off. I bought this on a whim and it worked amazingly well! Stain completely gone. Definitely worth buying.

It cleans very well.

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