To care for your beautiful new pieces, we suggest 'less is more' with natural materials like marble, stone and concrete. Please use warm water, and a non- abrasive cloth or sponge and a safe eco-based cleaner that is specifically recommended for ceramic/marble/stone use. Please avoid using any harsh cleaners with acidic substances that will damage and dull the stone. You can also use a specific marble/stone protector spray so that you only need to dust and wipe down with a microfibre cloth when needed. Using coasters and placemats will protect longevity of your pieces. The concrete and terazzo pieces are suitable for indoor and outdoor use. We suggest that the marble pieces are for indoor use only as cracking, bleaching or staining is a natural occurrence when exposed to the harsh weather elements.
