Storing oiled cast iron properly prevents rust and maintains its seasoning. Here's how:
Step-by-Step Guide to Storing Oiled Cast Iron
1. Clean the Cast Iron
- Rinse: Immediately after use, rinse the cast iron cookware with warm water. Use a non-abrasive sponge or brush to remove food particles. Avoid harsh soaps unless absolutely necessary.
- Scrub Stubborn Residue: For stuck-on food, use a pan scraper or a chainmail scrubber. You can also boil water in the pan for a few minutes to loosen debris.
2. Thoroughly Dry the Cast Iron
- Dry Immediately: This is the most crucial step in preventing rust. Use a clean, lint-free towel to thoroughly dry the pan inside and out.
- Heat Drying (Optional): For added assurance, place the dried cast iron on a stovetop burner over low heat for a few minutes until any remaining moisture evaporates. Turn off the heat and let it cool slightly before proceeding.
3. Apply a Thin Layer of Oil
- Oil Type: Use a cooking oil with a high smoke point, such as vegetable oil, canola oil, or shortening. Flaxseed oil was once recommended but is not generally favored due to its tendency to flake.
- Application: Pour a small amount of oil (about a teaspoon for a 12-inch skillet) into the pan.
- Rub it In: Use a clean cloth or paper towel to rub the oil evenly over the entire surface of the cast iron, inside and out, including the handle.
- Buff Away Excess: This is key! Use a clean, dry cloth or paper towel to buff away as much oil as possible. The goal is to leave a very thin, almost imperceptible layer. Too much oil can become sticky or gummy.
4. Proper Storage Locations
- Pantry/Cabinet: Store the cast iron cookware in a dry location, such as a pantry or kitchen cabinet. If stacking pans, place a layer of paper towels or a kitchen towel between them to protect the seasoning.
- Oven (If Dry): If your oven is not prone to humidity, you can store cast iron inside. Make sure the oven is completely cool and dry before storing.
- Hanging: Hanging cast iron on a wall-mounted rack or oven rack is an excellent option for air circulation and display.
- Avoid Damp Locations: Never store cast iron in a damp or humid environment, such as under the sink, as this will promote rust.
Tips for Long-Term Storage:
- Regular Use: The best way to maintain cast iron is to use it regularly. Cooking with it helps to reinforce the seasoning.
- Re-Seasoning: If rust appears, remove it with steel wool, wash, dry, and then re-season the cast iron.
By following these steps, you can ensure your oiled cast iron stays in excellent condition and remains rust-free for years to come.
