Cleaning: Lukewarm water, a pH neutral cleaner or methylated spirits is best for regular cleaning. Wipe surfaces with a damp chamois to avoid streaks. Wipe off anything spilled immediately, taking care not to spread the spill. Rinse the spill area with plenty of water.
Cleaning products: Do not use abrasive cleaners (powders or pastes like Jiff) as these products can scratch the stone.
Periodic maintenance: Use a good quality impregnation sealer every couple of years for granite. Marble or limestone need to be sealed on a more frequent basis.
Stone flooring: Flooring needs to be cleaned regularly with a dry dust mop. Sand and dirt do the most damage to the stone surface due to their abrasiveness.
