It is generally not recommended to use a self-cleaning oven on cast iron pans. Self-cleaning ovens utilize extremely high temperatures to burn off any food residues and grease, which can be very effective for regular oven cleaning. However, this intense heat can have adverse effects on cast iron cookware, particularly on its seasoning.
Cast iron pans are seasoned with a layer of polymerized oil, which creates a non-stick surface and protects the iron from rusting. The high temperatures of a self-cleaning oven can potentially strip away this seasoning, leaving the cast iron vulnerable to rust and making it lose its non-stick properties.
Additionally, the high heat can cause the cast iron to expand and contract rapidly, which might lead to warping or cracking of the pan.
To clean a cast iron pan, it's best to use gentle methods to preserve its seasoning and quality. Here's a recommended way to clean a cast iron pan:
- Let the pan cool down after cooking.
- Use a soft brush or sponge and warm water to gently scrub off any food particles.
- If needed, add a small amount of mild dish soap. Avoid using harsh chemicals or abrasive scrubbers.
- Rinse the pan thoroughly and dry it completely using a towel or by placing it on low heat on the stove.
- Apply a thin layer of vegetable oil or flaxseed oil to the pan to maintain or restore its seasoning.
By following these steps, you can keep your cast iron pans in excellent condition and prolong their lifespan. If you do accidentally damage the seasoning or notice rust on the pan, it's possible to re-season it to restore its non-stick properties.
