Dust marble and travertine surfaces twice per week with a soft cloth. Both marble and travertine stain very quickly, especially if liquids are left untouched on the surface. When you drop something, clean it up right away. Waiting too long can turn a simple spill into a stain, which can be difficult and sometimes even impossible to get rid of. Immediately clean orange juice, coffee, wine, and other drinks (or food) with strong pigments, and rinse with a clean, damp cloth. Never leave water on marble or travertine surfaces as it can cause stains.
Clean as gently as possible, never using abrasive cleaners or dusting sprays. Wash marble and travertine periodically with a cloth dampened with lukewarm water, and if necessary, some mild dishwashing liquid. Only use soap solutions that are potent enough to wipe off the dirt but mild enough to keep the limestone unharmed. Gently run the cloth over the surface, making a circular motion in the spots that need a little extra pressure. Remove the soap with another damp cloth and wipe the limestone dry.
