Specialist assessment, controlled restoration and a finish tailored to the stone and the property.
Acidic liquids can chemically alter marble and leave pale, dull marks. Ordinary cleaning will not remove them. The affected surface must be professionally refined and blended with the surrounding finish.
Lemon, vinegar, wine, bathroom products, limescale removers and acidic cleaning chemicals can all etch calcium-based stone.
Some marks are etches, some are stains and some are both. Correct diagnosis prevents wasted effort and unsuitable products.
