Our ProQuartz Tapas (servers, cutting boards, chopping boards) are hard wearing and strong. After use, simply wipe with warm water and a non abrasive-cleanser, and rinse well with clear water. Stubborn stains e.g. berry juices, wine, olives can be removed using the same cleaning agent, with a bit of rubbing to remove the stain. Do NOT use harsh chemicals or aggressive cleaners on the stone as these will damage the surface. The Tapas are not dishwasher proof.
