Marble

To preserve the brightness and luster of old or new marble in good condition, wash with a clean cloth and fresh, lukewarm water. Twice a year wash with a mild detergent to remove any residue.

Draw stains out of marble by poulticing. The principle of poulticing is to keep the necessary bleach or solvent moist for a long period while the stain is drawn from the marble into the poultice, which will absorb it. "Whiting" (A fine marble dust) can be mixed with the suitable cleaning agents and spread on the stain to serve as a poultice, or an absorbent white paper (blotter, paper napkins or cleansing tissue) can be soaked in the required solution and placed on the stain. In either case, keep the poultice moist while the stain is being drawn out of the marble. This is easily done by covering it with a piece of plastic wrap material. The process may take from one to 48 hours, depending on the type and age of stain.
