Before you try anything: always speak to a professional before cleaning, treating or applying any product to your stone. Every slab is different, and the wrong product can cause permanent damage. Contact us or a qualified stone restorer first.
Quick answer
Carrara marble etches when acids touch it and stains when oils or dark liquids soak in. A sealer slows staining but does not prevent etching. Clear protection film does both: acids and pigments sit on the film and wipe away, and the stone underneath stays exactly as installed.
Key points
- Carrara is softer and more porous than it looks.
- Bathroom products etch vanities as readily as food etches kitchens.
- Grey tones hide faint stains but not etching on a polished slab.
- Honed Carrara suits Matte/Satin film; polished suits Gloss.
The marble in half of Sydney's renovations
Carrara (Bianco Carrara) is quarried in huge volumes around the town of Carrara in Tuscany, which keeps it more affordable than Calacatta or Statuario. Slabs are sold in commercial grades that describe how white the background is and how dense the veining is. Whatever the grade, the chemistry is the same: calcite, which reacts with acid.
Because it is affordable, Carrara ends up in hard-working rooms: family kitchens, laundry benches, kids' bathrooms and café tables. Those are exactly the places where acids and oils are spilled every day.
Carrara vanities: the overlooked problem
Most people think of lemons and wine, but bathroom vanities etch too. Toothpaste, mouthwash, perfume, hair products and bathroom cleaners containing acids leave dull drip marks and rings around taps. Soap build-up cleaned off with a vinegar spray is one of the most common causes of a hazy Carrara vanity we are called to.
Film makes a vanity far easier to live with: normal non-abrasive cleaners are fine, and nothing that drips from a bottle can etch the stone.
