Was reading an article in Grit magazine about cast iron cookware and how to clean up and reclaim old ones.They missed this tip if you find some old pans and want to clean them up and reseason them.
If you have a self cleaning oven just put them in there and run the cycle.If you don't have a self cleaner I'm guessing turning your oven to it's highest temp will work.Or you can build a big fire and bury your pots in it I hear that works well never done that one to be truthful so YMMV.I have done the self cleaning deal and it works perfectly.Got cast iron right better get on it if you don't.
