Can You Put Cast Iron in the Dishwasher? Yes or No?

Putting cast iron in the dishwasher is not a good idea. Cast iron pans need special care to keep them in good condition. Here’s why:

• Rust Risk: Cast iron is prone to rusting if it gets wet and is not dried properly. Dishwashers use water and detergent to clean dishes, which can lead to rust forming on the cast iron surface.
• Seasoning Protection: Cast iron pans are usually seasoned with oil to create a non-stick surface. The high heat of the dishwasher and the harsh detergents can strip away this seasoning, leaving the pan vulnerable to rust and making it less non-stick.
• Damage to Finish: The abrasive nature of dishwasher detergents and the high water pressure can damage the finish of cast iron pans, causing them to become dull or develop scratches.
• Warpage: The extreme heat and rapid cooling cycles of the dishwasher can cause cast iron pans to warp or crack, ruining their shape and making them unusable.
• Dishwasher Damage: Putting cast iron in the dishwasher can also damage other dishes and the dishwasher itself. Cast iron pans are heavy and can bang around in the dishwasher, potentially causing damage to other items or the dishwasher’s interior.

Instead of using the dishwasher, here’s how to clean cast iron pans properly:

• Hand Wash Only: After cooking with your cast iron pan, let it cool down to a safe temperature. Then, hand wash it using hot water and a soft sponge or brush. Avoid using harsh scrubbers or abrasive cleaners that can damage the seasoning.
• Minimal Soap: If your cast iron pan has stubborn food residue, you can use a small amount of mild dish soap. However, avoid using too much soap, as it can strip away the seasoning.
• Dry Thoroughly: After washing, dry the cast iron pan immediately and thoroughly with a clean towel. Ensure there is no water left on the surface, as this can lead to rusting.
• Re-season if Necessary: If you notice that the seasoning on your cast iron pan has been damaged or stripped away, you can re-season it to restore its non-stick properties. To do this, coat the pan with a thin layer of oil and heat it in the oven at a low temperature for an hour.
• Store Properly: To prevent rusting, store your cast iron pans in a dry place with good air circulation. Avoid stacking them on top of each other or storing them in damp areas like under the sink.

By following these steps, you can keep your cast iron pans in great condition and avoid the potential damage that can occur from putting them in the dishwasher.
