Tips for Maintaining Your Outdoor Grill
Between the Burner and Grate: Sometimes called the radiant or flavorizer bar, this part of the grill evenly distributes heat to the grate above and produces smoke when food drippings seep down. "Most of the wear is in the flavorizer bars, because they see the most heat and grease," says Brooke Jones of Weber Grills. Brush off grease and debris from the metal plates because they can trap moisture and cause rusting. Replace lava rocks or ceramic briquettes if they give off a rancid flavor.
Grill Covers: Keeping a grill protected from the elements is the easiest way to preserve it. Covers should have a cloth inner lining to draw moisture away from the metal. A simple plastic sheet holds moisture in, creating a humid environment around the grill, which can lead to rusting. Use a canvas, cloth, or vinyl cover that fits the grill appropriately. Keep in mind that UV rays beak down cheaper, generic covers.
