As a precursor to cleaning with chemicals, stone floors should be dry mopped to remove dust and debris, which can, when walked upon, cause scratches in the surface of stone. Placement of entryway mats is also crucial to preventing that debris from ending up on the flooring. Damp and wet mopping with a neutral cleaner that is formulated specifically for stone floors removes dirt build-up without damaging the floor finish. While wet mopping, water should be changed frequently to avoid leaving dirty streaks.
Any acidic, abrasive or ammonia-based cleaners should be avoided, as they will damage sensitive stone floors. Less frequently, stone floors can also be cleaned and polished with a non-abrasive white autoscrubber pad.
