Dust mop interior floors frequently using a clean non-treated dry dust mop.
Sand dirt and grit do the most damage to natural stone surfaces due to their abrasiveness.
Mats or area rugs inside and outside an entrance will help to minimize the sand, dirt and grit that will scratch the stone floor.
Be sure that the underside of the mat or rug is a non-slip surface. Normally, it will take a person about eight steps on a floor surface to remove sand or dirt from the bottom of their shoes.
Do not use vacuum cleaners that are worn. The metal or plastic attachments or the wheels may scratch the surface.
