How do you recondition a lightly rusted cast iron pan?
I have some cast iron cookware that is over 100 years old, that I still use! Rinse it out good, then dry it. Rub the inside of the pan with something like Crisco or bacon grease. Then put it in a pre-heated oven at about 350 degrees. Leave it in there for about 15 or 20 minutes. Take it out and let it cool. When cool wipe it out and check the inside of the pan. You might need to do it a second time. Cast iron cookware if taken care of will last almost forever.
