1 get rid of the rust with a wire brush and or scourer
2 if you have heaps of rust, fill it with water and bring it to the boil and simmer for 20 minutes and scour again
3 pre heat oven or bbq to 400 degrees.
4 wash with hot water and a stiff brush
5 rinse and dry
6 apply warm oil over the entire thing with a cloth. wipe off excess (it will burn off anyway)
7 place upside down on the grill (if doing this inside, line the oven with foil to catch the oil that burns off)
8 leave it for an hour and allow to cool
9 coat with oil again and reheat for another hour
10 you should have a good hard black surface now.
Cheers,
