What Acid Etching Looks Like on Marble
Etching is surface damage from acid, not a stain. Learn how to tell a dull etched spot from dirt and why cleaning alone cannot remove it.
Etching is not a stain
A stain is material that has entered or collected in the stone. Etching is a change to the surface caused by acids such as lemon juice, wine, tomato sauce, vinegar, or harsh bathroom cleaners. It often appears as a pale, dull, or hazy patch that follows the shape of a spill.
Because the surface itself has been altered, more cleaner will not make the spot disappear. Scrubbing harder can spread the damage or add scratches.
The correct repair
Light etching may respond to professional honing or polishing, depending on the desired finish and the surrounding surface. Widespread etching may require a larger section to be refinished so the sheen is even from edge to edge.
Wipe acidic spills promptly, use a pH-neutral stone cleaner, and avoid abrasive pads. If etching is recurring in a kitchen, ask about an anti-etch treatment in addition to normal sealing.
