Use enough baking soda to make a paste with the white vinegar and apply it to the rusty area. Leave until dry then apply a bit more white vinegar and use some elbow grease to get every bit of rust off. The cookware looked like new!
It does take some effort, but well worth the results. After cleaning the rust off, apply vegetable oil to wipe off the remainder of the rust and use some table salt to polish up the cast iron.
