Lenicany 6Pack Pumice Stone for Toilet Cleaning Bowl Stick,Powerfully Cleans Hard Water Rings，Calcium Buildup & Stains, Suitable for Cleaning Toilet, Bathtubs, Kitchen Sink, Grill

You ever get those oven bake ons? I’ve used these on those oven crusted spots (yes I keep one only for the oven) no fumes, excellent cleaning.

Use these to clean the waterline in my swimming pool and it works very well!

They work

Unfortunately a bit like nails on a chalkboard. But, makes cleaning hard water from the toilet bowl so quick it hardly matters.

I used the pumice on the calcium build up in the toilet. It crumbled away fast, but cleaned the area without seeming to scratch the surface. I had to keep the pumice wrapped while working with it to keep it intact until I finished

It did not scratch up my toilet. I was worried, but it got the yellow stains out.

My new go to when cleaning. Especially the stove.

Works great! I had a stubborn ring around my toilet that I purchased a bunch of cleaning products prior but none worked like the stone. Best thing was no odor or having to wait so it can set. Just make sure to keep stone and surface wet.

These are fantastic for cleaning toilet bowls! They easily and quickly remove hard water deposits and the black stuff that a plastic bristle brush and cleanser will not. No nasty chemicals go into the water system. They are consumed during use. I would say they are good for 3 uses on moderately funky toilets.

I used these for the hard water stains on my toilet after months of failed attempts of other products and this completely made them disappear! I just hate the noise it makes while scrubbing the bowl! Still totally worth it!
