Season Your Grills
Seasoning cast iron grills will help keep them from rusting and help stop food from sticking to them. To season your Cast Iron Grills, wipe them down with lard or shortening and cook in the BBQ at 350 degrees for 1 hour. (You could do this up to 4 times for maximum protection) This is most effective if done when the grills are new and have never been cooked on before
