Human: What is the best way to remove rust from a cast iron pan? Assistant: 
The best way to remove rust from a cast iron pan is to use a combination of baking soda and vinegar. Sprinkle some baking soda over the rusty areas, then add a few drops of vinegar. Let it sit for about 10 minutes, then scrub with a damp sponge or brush. Rinse off any excess baking soda and vinegar, then dry the pan thoroughly before using.
