Earlier quoted context omitted.
Hm. My cast-iron skillet I've used for 20 years doesn't stick. Ever. If there's a little stuck-on stuff on the bottom after use (should have put a little wine in there, gotten that flavor back into the dish, oh well) then a Scotch-brite bad and 30 seconds fixes it.
My cast iron is 4 years old and every time I use scotch-brite on it, I have to spend hours stinking up my house with flaxseed oil to reseason the pan because scotch-brite makes little dots of shiny iron show up.
