Prep your gas grill for summer to prevent clogged burners and grease fires. Your instruction manual will tell you how to clean out the burner ports and the manifold, the assembly that mixes gas and air and channels it to the burner.
Spiders like to nest inside, and they can block gas.
Clear all openings with a bottle brush or pipe cleaner. Get parts, if needed. Replace any burner or cooking grate that has a lot of rust or weak spots. New lava rocks will pep up your cooking, since clean ones distribute heat better and cause fewer flare-ups. Check for leaks.
