How do you maintain cast iron grates on an outdoor gas grill? We are interested in purchasing a new grill. Most of the new gas grills that we have interest in are sold with cast iron cooking grates. We are not familiar with that type of cooking grate. We would like to know how good they for grilling plus the ease of clean-up and maintenance. Do they rust and if so, how do they clean-up? Thank you.
Cast Iron is amazing to cook on, the best thing in my mind. You must treat it similar to a cast iron pan, it will need to be seasoned and cared for. To season it you will need to pre heat your oven to 350f (make sure you can fit your grill in the oven otherwise use the barbecue itself, keeping temperature in mind) wash the grill quickly and dry completely. Rub a thin coat of flax seed oil over every piece of the grill, don't miss a spot. The oil should not be dripping. Bake the grill in the oven (or barbecue) for 30-45 minutes, cool it completely, repeat this process at least 3 times. Your seasoning is done. Make sure to clean the grill after every use by wiping away any char or food particles and rub with a little oil.
If you do this, and regularly oil your grill, it may last a few generations.
