After cooking the grates on our barbeque grills get greasy and grimy. You can skip the scrub brush and grab a can of Coke or any other cola soda. Remove the grate, place in a heavy duty trash bag, and let soak (flat) for at least 20 minutes. Rinse off with the hose. The cola contains strong acid that will break down even stubborn, cooked on food. Hmmm! Wonder what it does to the stomach!!!
