Ask Curtis Stone a question here. How do you clean you cast iron pan after cooking with it?
Soap can break down the patina layer on your cast iron so you should only use hot water. Regular cleaning of your cast iron includes a rinse and softly scour in hot water, using something soft like a plastic spoon dislodge any stuck on peices. Never soak in water as this makes rust, then re-season your pan, then use either crisco or another solid oil to season it.
