How do you get a stain out of black granite?

Mix a poultice paste of baking soda and water (for oil-based stains), or baking soda and peroxide (for others), until it’s as thick as peanut butter. Spread the mixture over the spot, cover it with plastic wrap that you’ve poked a few holes in, and secure it with masking tape. Let the poultice paste stand for 24 hours.
