If you need to clean them, scrub them good with soap and water... then throw them in a self cleaning oven and put it on clean. DON'T DO THIS WITH WOODEN HANDLED POTS/PANS/SKILLETS. Self cleaning ovens are the best-when done, tip out the ash and season as above-we use olive oil and do 2 thin coats-will gum up if too thick. Many good suggestions above. We shy away from ALL the non stick stuff-not healthy at all, gives off gases, scapes result in toxins release etc. but big chemical company bucks behind it so no big deal :-) same as those soft-rubber-like gloves and stuff-HOW can that stuff be safe/healthy? Cast Iron and stainless is the way to go-you can pick up a skillet and a dutch oven or large pot at a flea market for like 5-10 bucks each and cook for 100 years or more with them!
