Regularly dust the surface and wipe the marble with a damp cloth when necessary, possibly with a mild, acid-free cleaner. Remove the detergent with a clean, damp cloth. Marble is limestone and does not tolerate any kind of acid (juice, wine, ketchup, etc.) Marble is delicate and should be treated with care. Always use table protectors for drinking glasses and hot items to keep your table beautiful and free of marks and stains.
