Preparing your grill for summer cookouts should begin with a thorough cleaning using dish detergent. Begin by disconnecting the ignition wires and the igniter. Remove the propane tank , flame guards and the grill grates. Allow the grates to soak in a container with soapy water while you are cleaning other components of the grill. After all parts are dried, reassemble the grill. Each time you light your grill, allow the grates to become hot and scrape with a wire brush to remove any food and residue from prior usage of the grill . If the grill is exposed to the weather it should be covered when not in use. Enjoy cooking out with a clean and well functioning grill.
