Re: Frying Pans!
Bare metal pans are better if they are seasoned, as was said before.
I once had a pancake pan that worked very well once seasoned, and so wasn't washed, just thoroughly wiped.
Non-stick pans don't need to be seasoned.
Whether I wash mine depends what's been cooked in it, and how messy it is, but I tend to wipe it thoroughly with paper and use it again, once or twice, and I do wash it after every second or third use.
It also depends on whether my dishwasher is getting full or not! It's only a small one.
