Dull spots that cleaning will not fix Etching is the reason most kitchen stone looks tired
Most calls we get on dull stone are not about dirt. They are about etching, which is what happens when something acidic, like lemon juice, wine, tomato sauce, vinegar, or a citrus cleaner, sits on a calcium-based stone and dissolves a tiny layer of the surface.
Etch marks look like dull rings, water spots, or hazy patches that no amount of mopping touches. They are surface damage, not staining, so cleaners cannot reach them. Honing followed by polishing is what actually removes them.
Foot-traffic dulling is a separate issue. Pathways through an entry or kitchen lose sheen from abrasion over time, and a polish refreshes them. Etching needs honing first, then polish. We figure out which one you have before we quote the work.
