WHY IS IT IMPORTANT TO SEASON CAST IRON COOKING GRILLS Just like a cast iron frying pan it is necessary to season, and re-season, cast iron cooking grids. The oil will help protect the porcelain coating, decrease sticking, and protect damaged or worn grids from rusting. Only use household cooking oils (Olive, Vegetable, Peanut, Sunflower, Canola, to name a few).
