cooking oil counter acts and gives a sticky coating. Shortening like Crisco is best. New Year's day id the day I reseason mine. I have an old cookie sheet and turn the pans upside down so the seasoning doesn't pool. I never use soap, either.

I use boiling water to clean, wipe dry, and wipe inside with thin layer of shortening. Cooking oil doesn't work the same as shortening for seasoning.
