4TH Pumice Stone for Toilet Bowl Cleaning,Scouring Stick with Handle,Powerfully Away Limescale Stain,Hard Water Ring, Calcium Buildup,Iron,Rust.Remover for Tile Bath-tub - 2 Pack

Used this for my tub for hard water stains, worked great!

Takes a little scrubbing but works the way I needed.

You dont need to much elbow work.

I’m a boy Mom with 4 toilets, everyone needs these in their life!! Removed all the rings I couldn’t get off with anything else! Just buy them, you won’t regret it!!

This thing really does work for stubborn hard water stains, just needs a lot of elbow grease & patience. The only downside of this product is that it is a bit difficult to get the underside of the bowl where the water comes out because of how it’s shaped (see in pics). Worked pretty good overall just be prepared to put some work into your scrubbing.

We have lots of iron in water that etches a ring in the toilets. I’ve tried EVERYTHING (like Iron Out) and nothing has been powerful enough to remove rings and stains. In just minutes with this tool, toilets looked showroom clean and pristine. So very happy to buy these.

Worked amazing on hard water stains and build up! Just wish they lasted a bit longer

I was like, how in the world does this work without scratching the crap out of my toilet?!!?? But when I tried it on my toilet ring, I saw the magic! It somewhat disintegrates as you use it and doesnt scratch. It really removes that hard horrible ring in the toilet!! Its not too rough of a pumice...not like a heel pumice or a rock. It totally works.

This works great on toilets. Quick, easy, and painless.

Used it for several hard water stains and it got rid of them
