Granite is the hardest natural stone, it is stain resistant and its durability make it a natural choice for countertops.
Natural stone can get stained if a spill is not cleaned quickly. Sealing the surface once a year is recommended to protect the stone from patches and stains.
Granite will darken if a spill is left overnight; to remove the stain, a poultice should be used. Granite is chip and scratch resistant if used under normal conditions.
Marble can be etched and stained by acidic or oil-based products and it can be chipped and scratched under normal use.
Do not use cleaners that contain acid, bleach, ammonia or vinegar. These products can harm your natural stone.
