Same as cleaning your pizza steel, you should let it cool completely before treating, if you are going to clean it, then scrape off burnt food first, and do not use harsh soaps. To season it you can use flaxseed oil or any high smoke point oil, pour a thin layer of oil and do not put the steel straight into hot oven, heat it after placing the steel inside. Carefully watch the seasoning process to prevent fires as seasoning requires high temperature.
