How To Remove Stains From Stone Surfaces

Marble, travertine, limestone & onyx are all soft materials prone to marking because of their calcium carbonate structure. Acidic liquids react with calcium carbonate and literally eat away a tiny piece of the polished/honed surface, creating dull spots typically called an etch. Contact from acidic materials like lemon juice, wine, coffee, fruit juice, etc., can create an etch. The more acidic the liquid, the faster and more profound the etching occurs. Etching can not be “mopped away” and calls for professional intervention.

An etch is not a stain; it changes the stone’s surface like a scratch. Etching generally appears as a light, dull mark or splotch. Penetrating sealers cannot stop etching as they are beneath the stone’s surface and not a physical barrier between the acidic liquid and the stone.

Why Seal?

Calcium-based stones have three main factors related to maintenance; they are porous and etch and scratch easily. Although a penetrating sealer cannot stop etching and scratching, it can reduce the stone’s porosity, improving its stain resistance and making repair easier.

How to Repair an Etch?

If the etching is minimal (you can see it, but it is not rough enough to feel), you might be able to polish it out using a marble polishing creme. If the etch is deep and you can feel the surface is rough, you will need to have it mechanically removed.
