- Nonpolished marble is very porous, stains easily, and must be sealed with a commercial sealer. Do not use varnish or lacquer to seal marble; it quickly peels off. Polished marble is less porous but can still be stained; a commercial marble sealer is also recommended for this finish.
- Marble floors look great after being damp-mopped using either clear water, an all-purpose cleaning solution in warm water, or a mixture of 1 cup fabric softener and 1/2 gallon water.
- Self-polishing liquid wax is a fast, shiny finish for marble. Occasionally, you'll have to strip the wax buildup and rewax. After applying the stripper according to the manufacturer's directions, rinse the floor thoroughly, then apply wax.
- Use either a water-base self-polishing wax or a paste wax. If you use a paste wax, test it in a corner to see if it will discolor the flooring. If a solvent-base paste wax is used, rewax to strip the old wax and to renew the shine.
