How to take care of marble?

Clean stains immediately with a soft cloth, especially if acidic substances (e.g. lemon juice, vinegar, or tomato sauce) or colored liquids (e.g. wine or coffee) have come into contact with the surface.
Clean gently, using a mild detergent with a neutral pH.
Dry thoroughly to avoid water stains.
Do not use acid-containing cleaners or abrasive tools.
Apply marble polish for shine if necessary. Re-apply the protectant annually.
Avoid dragging objects to prevent scratching.
Seek professional help for deep stains or scratches.
