How to Season a Carbon Steel Pan
Michele, this is definitely a must read article.
FWIW, my SOP with my cast iron stuff is to after use, brush out with hot water (as hot as the tap can deliver), then put on stove on low heat, enough to dry it out but not burn the oil.
Treat with oil — minimal amount, just enough to allow for a thin coat — using kitchen paper towel, then let it be on heat for a bit to let it soak in.
Let cool down.
Put into storage.
I would imagine the process is similar with carbon steel.
EDIT: My oil of choice is rapeseed oil.
