I recently acquired 7 man grates from my dad for free. He didnt take great care of them and they started rusting. So i ran the clean cycle in the oven with the grates in there to get the crud off. The wife did not like this. It looked like there was a fire in our kitchen with all the smoke. I then hit them with a wire brush and vegtable oil. They are seasoning now and im cooking 2 filets on them in a bit. They arent perfect but after seasoning i think they will be great! Before After Im also braving the rain to do this. Thats how excited i am!
