My mother, whenever she came to our bhouse, for years, would clean the cast iron pans until they were stripped of their seasoning, and we'd have to redo them when she left!

~I still have my Grandmothers cast iron frying pan....I have been married for over 27 years and she had it for a life time before me.....never ever ever ever soak the pans,....oil is the cast irons friend, and I vary the types of oil I use....you would not believe the difference in the taste of the foods with an old well seasoned pan!!
