Marble is a natural stone material that is organically porous, soft, and more sensitive to chemicals than other stones such as granite. The marble stone will show wear sooner than other stone surfaces, but it can be restored with correct care and polishing by a stone care professional or restoration specialist. Since marble is a porous stone, any substances that are left on marble surfaces can stain. We highly recommend cleaning any spills or food crumbs immediately with a lightly dampened cloth as this will minimise the imperfections to the item. Avoid leaving cold cups or drink bottles as water condensation will also stain the marble. We highly recommend the use of coasters and placemats to further protect the integrity of the stone. Examples of substances that may stain, etch, or mark the marble are: Sauces Oils Acidic Salad dressings Fruit juices Soft drinks Wine and other alcohols If any of these substances spill on your marble surface, we recommend cleaning immediately with a damp cloth and wipe dry. Blot spills as wiping the area will spread the spill. Avoid the use of cleaning solutions below as some may stain, corrode or tarnish marble surfaces: General-purpose cleaners Bathroom cleaners Grout cleaners Descaling solutions Vinegar Bleach Ammonia Abrasive scrubs Acid based cleaners Soft cleansers
