Why is it important to season cast iron grids?

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 HIGH SMOKE POINT OILS We recommend using one these – Avocado Oil – smoke point (260°C / 500°F) Rice Bran Oil – smoke point (255°C / 500°F) Canola Oil – smoke point (204°C /400°F)
