How to Clean Rust Off a Cast Iron Skillet
- 1). Scrub the skillet with steel wool and warm water. Continue scrubbing until all the rust has been removed. If the warm water doesn't seem to do a thorough job, use a harsh cleaner such as Ajax or Comet. Rinse the skillet with cold water and inspect the skillet. Repeat the process until all the rust has been removed.
- 2). Wash the skillet with a mild dish detergent and warm water. Dry the skillet with a towel.
- 3). Re-season the skillet. It is necessary to re-season the skillet to prevent food from sticking to the skillet. Coat the skillet with vegetable oil. Work the oil into the skillet with a paper towel. Place the skillet upside down in an oven on a baking sheet. Bake the skillet at 350 degrees for one hour. Wipe the skillet with a paper towel and allow it to cool.
- 4). Protect the seasoned coating by always cleaning it with oil and salt. Never use soap to clean a seasoned skillet. Clean a dirty skillet with oil and salt, and rinse it well with hot water. Place the skillet over a low heat and allow it to thoroughly dry.
