I have been using cast iron for about 30 years, and it is very simple. I simply boil the pans after using if they are very messy. If not, I just run a sponge over them, and rinse. They never seem to need reseasoning, but if they do, just apply a light coat of oil and bake them at 350 degrees or so for about an hour. The older they got, the blacker and nicer they become. In short, they are wonderful!
