Care & Maintenance:
Floor Surfaces: dust mop interior floors frequently using a clean, nontreated 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.
slate is chemically sensitive so only mild pH neutral cleaners should be used. soapless cleaners are preferred because they minimize streaks and film. mild, phosphate-free, biodegradable liquid dishwashing soaps or powders or stone soaps are acceptable if rinsing is thorough.
Showers and Baths: soap scum can be minimized by using a squeegee after each use and using liquid as opposed to bar soaps. to remove soap scum, clé recommends the use of Miracle Porcelain & Ceramic Tile Cleaner.
