You read that here? I might hold my washed skillet upside down over a burner briefly to make sure it's good and dry, but that's about it. Perhaps it's one of those made-up things, thinking that oily residue will polymerize or somesuch. My pans have acquired a good seasoning without doing that. I also see recommendations out there to oil your cleaned pan and heat it past the smoke point every time you use it. I see no need to do that, either.
