Clean natural marble using a soft cloth or nonabrasive sponge with warm water and a pH-neutral cleaner made for natural stone.
Wipe spills promptly, especially cosmetics, oils, coffee, wine, citrus, and other acidic substances.
Do not use vinegar, lemon, bleach, abrasive powders, harsh bathroom cleaners, or metal scrubbers. These products may stain, scratch, or etch the surface.
Periodic sealing may help reduce moisture and stain absorption. Consult a natural-stone professional for recommendations based on the stone, finish, and installation area.
