"It works. But only on porcelain, and only if everything stays soaking wet."

The science

  1. Soft stone, hard glaze.

    Pumice is porous volcanic glass. Wet, it crumbles and wears down while it grinds away the softer mineral scale, before it can bite into fired porcelain glaze.

  2. Dry means scratches.

    A dry stone drags hard grit across the bowl. Scratches give minerals a rough spot to grip, so the ring comes back faster and darker than before.

  3. Porcelain only. Full stop.

    It will scratch plastic seats, enameled steel, colored or specialty-coated bowls, and anything with a non-stick glaze. If you don't know the material, skip it.

Do it right

Soak the stone first, keep the water in the bowl, use light pressure, and stop to check often. Gray marks are pumice residue and wipe off. Scratches don't.
