rusted cast iron
Our story so far:
The outside (emphasize: NOT the cooking surface) of a cast iron skillet has rusted.
I've cleaned the rust off with an SOS pad, water, and steel wool. and dried it as thoroughly as I can.
What is the next step to protect the outside (again, NOT the cooking surface) for the future?
I'm guessing some kind of oil and maybe putting in a low oven for some time.
But what kind of oil? neutral cooking oil? something else?
thanks in advance
I try to use my ever growing collection of cast iron as much as possible, but rust is inevitable, I guess?!? I usually scrub with cheap salt, rinse well under HOT water and "dry" by setting back on burner till pretty hot. Then a dab of bacon grease... that's what my Grandmother always did. I wipe out inside with paper towels and continue wiping exterior with same paper towel. Works for me.
Crisco shortening. Heat the pan in the oven, melt the Crisco, wipe exterior with a rag. Follow the procedure given here, where it applies:
Normally, the Crisco would be melted right in the hot pan. Is there some reason you wouldn't want to do it that way? You could melt it separately.
