I DO NOT recommend the following methods of cleaning:

Self Cleaning Oven - Although not as great a risk as throwing it in a
fire, the intense heat of a self cleaning can warp a skillet. There is
also a risk of warping the piece.

I recall that this was suggested, and think it is an excellent idea.
Hmm - warping?

I have some old pans and skillets, Griswold and Wagner and 2 without
any name at all, as well as 2 new Lodge skillets that I'd like to
clean up. I guess the answer is, if you are worried, don't do it. But
Lordy, it's a lot of scrubbing if I don't use the oven.

After cleaning, I'm going to use either lard or food grade coconut oil.
Any comments?
