Default Re: Observation: seasoning of cast iron skillet

Dan, the theory: If the surface of the cast iron is too smooth the seasoning wonít stick properly to the piece. Sort of like SS or ceramic. So vinegar is used to etch the surface to be more adhesive friendly for the seasoning.

Image: A clear drinking glass that has gone through the dishwasher 3 times a week for the last 25 years.

Reality: The actual CI doesnít really care if it gets a 5% acetic acid soak for a few hours.
