Although some people try to wax their small marble tabletops, this runs the risk of turning the stone yellow. Use a polish that is specially designed for marble to protect your table without damaging the sensitive porous stone underneath. Although it won’t protect your table from the elements outdoors, it will give it some shine while providing an extra layer of protection from everyday wear and tear.
Make sure to clean the table thoroughly before applying the polish. Apply the polish according to the manufacturer’s directions, which usually specify using a small quantity applied in small circular motions. Since polish must be reapplied periodically, make sure to keep some on hand for use any time the marble starts to look dull.
