How to clean natural stone
Sweep off surface debris.
If you are cleaning a natural stone floor, you'll want to use a fluffy mop or brush that has soft, natural bristles. This will prevent the stone from getting scratched by brushes with abrasive bristles.
If you are cleaning natural stone countertops, a clean cotton rag or a handheld duster can remove surface debris. Sweep all the dirt and dust into a dustpan and dispose of it.
