If you want to really remove the rust by converting it back to good metal instead of just sanding it off, you have to use electrolosis. Go to Youtube and search on Cast Iron Electrolisis to see people restoring cast iron cookware. All it takes is a big plastic tub, water, Sodium Carbonate (Arm and Hammer Washing Soda - not baking soda), some scrap metal, and a battery charger.
