I snagged a great Lodge Sportsman Grill at my local flea market today. It looks pretty new but has some rust. The door seams to be the worst. Im cleaning the door in a vinegar bath now. Im going to use it a few times and see if I want to go any further with the cleaning. Whats the best way to keep it from rusting? Season like a skillet, vegetable oil? I dont want to paint it but I also dont want it to rust.
