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.
