I Can Make Your Cast-Iron Skillet Look & Cook Better Than Ever Before
After cooking in a cast iron skillet, do not use a detergent to clean it. That will destroy the seasoning (conditioning). Put hot water in the pan and bring it to a boil. Use caution here, do not put cold water in a hot pan! Let the pan soak for several minutes, then wipe it out with a paper towel. If something sticks, scrape it with a spoon to dislodge it. Do not use a brillo pad to scour it! An abrasive pad cuts into the seasoned surface too. Then, reheat the pan and apply a fine coating of shorting, oil, or lard. Do not apply enough to run. Just enough to wet the surface with a fine layer.
