I've done a few and have a couple more to do...it's just to hot out right now to mess with it.
Electrolysis method works best, but I won't mess with that unless it's really rusty. I tried burning off the old stuff in a small fire and it worked great, but I've heard that can destroy a pan if you let it get too hot or too uneven.
I don't have a self-cleaning oven, so I just put them upside-down on my gas grill outside, turn all three burners up to HIGH, and leave it for about an hour. Let it slowly settle to room temperature (which today is about 100). I use the method of extremely thin coat of Crisco, bring up to just starting to smoke, then let it cool. Repeat about four times.
I found it works best to rub with very light vegetable oil after each use.
