- Spray a heavy layer of Easy Off oven cleaner on the cast iron. This can be used to clean off heavy carbon build up, but will not remove rust.
- Place your cast iron in a trash bag and sit it outside in the sunlight. This will work in the cold, but works best on warm days.
- After 24 to 48 hours, you should be able to wipe it off or use a SOS pad to scrub the carbon off. If any is left, simply repeat the steps until clean.
- Once clean start the seasoning process.
*** NOTE: Make sure you use rubber gloves so that the oven cleaner does not get on your skin.
