I used one pumice stick on the toilet ring in our guest bath, and the stain lifted after a few steady passes

I was surprised how well the pumice sticks worked on old tile marks, and I saved two for later cleaning

I keep a pumice stick in each bathroom now, since it made the hard water line vanish without any spray

The long handle helped me reach under the rim, so I finished the bowl without getting my hands close

My wife asked me to try these stones on rust marks by the drain, and the sink looked fresh again

I tried one stone on grill grates after a cookout, and the stuck bits came off with plain water

Bought the set for my parents, and Dad said the toilet bowl cleaned up faster than with his usual brush

After moving into our rental, I used these stones on the bathroom sink and got rid of the crusty ring

Worked nicely on the sink stains

I bought extras for our downstairs bathroom
