Cleaning and seasoning your cast-iron skillet properly after each use is crucial to maintain its non-stick surface and prevent rust. Here's a step-by-step guide on how to clean and season your cast-iron skillet without rusting it:
Cleaning:
Allow the skillet to cool: After cooking, let the skillet cool down completely before cleaning. Avoid pouring cold water on a hot cast-iron skillet, as it may cause thermal shock and potentially damage the skillet.
Use hot water and a brush: Rinse the skillet under hot water to remove any food residue. Use a stiff brush or non-abrasive scrubber to gently scrub the surface. Avoid using soap or harsh detergents, as they can strip away the seasoning.
Stubborn residues: If there are stubborn residues that don't come off with water and brushing, you can use a small amount of coarse salt as a gentle abrasive. Sprinkle the salt on the skillet and use a paper towel or cloth to scrub the surface.
Rinse and dry thoroughly: Once the skillet is clean, rinse it well to remove any remaining debris. Pat it dry using a clean towel or paper towels. Make sure to remove all moisture from the skillet to prevent rust.
Seasoning: 5. Apply a thin layer of oil: After the skillet is dry, apply a thin layer of oil to the entire surface, inside and out. You can use vegetable oil, canola oil, flaxseed oil, or solid shortening. Make sure to coat the skillet evenly but avoid using too much oil.
Heat the skillet: Place the skillet upside down in an oven preheated to around 375°F (190°C). This prevents oil from pooling and helps it polymerize. Put a foil-lined baking sheet on the lower rack to catch any drips.
Bake the skillet: Let the skillet bake for about an hour to allow the oil to polymerize and create a protective seasoning layer. This process will help build up the skillet's non-stick surface. After an hour, turn off the oven and let the skillet cool in the oven.
Repeat seasoning: To enhance the skillet's seasoning, it's recommended to repeat the seasoning process several times. Each time you cook with the skillet, it will continue to develop a better non-stick surface.
General Tips:
- Avoid soaking the skillet in water or leaving it submerged, as this can promote rust.
- Do not use steel wool or abrasive cleaners, as they can damage the seasoning.
- Store the skillet in a dry place, preferably with a paper towel placed inside to absorb any moisture.
Regularly maintaining your cast-iron skillet by cleaning and seasoning it after each use will help keep it rust-free and ensure its longevity.
