That is basically cleaning and re-seasoning.
If you have any rust at all, you need to get rid of it. If it is minimal, smokeisgood's method could do the trick. You may even be able to do a hot water and ScotchBright cleaning, and cook up half a pound bacon. For heavier rust, you'll need a more aggressive cleaning, and a proper re-seasoning.
