As one of the hardest of the natural stones, granite is especially appropriate for use as flooring or countertops. An igneous rock, granite is impervious to damage from household kitchen acids such as vinegar, citrus drinks and sodas. Granite also handles heat extremely well; taking a hot pan from the stove and placing it on a granite countertop is perfectly all right.
Do remember, however, that some granite can be stained by some liquids or darkened by oils if not properly sealed with a penetrating stone sealer. Once sealed, granite shouldn’t require any special care other than regular cleaning with warm, soapy water.

Clean stone surfaces with a few drops of neutral cleaner. A mild liquid dishwashing detergent and warm water also works. Too much cleaner or soap may leave a film and cause streaks. Do not use products that contain lemon, vinegar or other acids on marble or limestone. Rinse the surface thoroughly after washing with the soap solution and dry with a soft cloth. Change the rinse water frequently. Do not use scouring powders or creams; these products contain abrasives that may scratch the surface.
