Caring for natural stone objects

What to avoid

Acids etch the surface: lemon juice, vinegar, wine, fruit juice, tomato sauce and many bathroom cleaners leave dull marks, even on sealed stone. Wipe spills straight away.

Avoid abrasive powders, scouring pads, bleach and ammonia. Do not put stone objects in the dishwasher, and avoid sudden temperature changes such as hot pans on cold stone.

Coloured liquids (coffee, oil, red wine) can stain porous stone. Use coasters and trays for bottles, glasses and cosmetics.

Everyday cleaning

Dust with a soft, dry cloth. For cleaning, use lukewarm water with a few drops of a pH-neutral cleaner or mild soap, then wipe dry with a soft cloth to avoid water marks.

For travertine with open pores, a soft brush helps remove dust from the pores.

Sealing

An impregnating (penetrating) sealer reduces how quickly the stone absorbs liquids. It does not stop acid etching. How often to reseal depends on the stone and how the piece is used; a simple test is to put a few drops of water on the surface — if it darkens within a few minutes, it is time to reseal.

Follow the sealer manufacturer’s instructions and test on a hidden area first.

Food and drink

Natural stone is used for serving boards, bowls and trays. Whether a specific finish or sealer is suitable for direct food contact should be confirmed for that product before you use or sell it that way. Ask us about the product you are interested in.

Onyx needs extra care

Onyx is softer and more brittle than marble. Lift pieces with both hands, avoid knocks and keep them away from the edges of shelves and tables.
