No, it is not safe to put uncoated cast iron in the dishwasher. Cast iron cookware requires special care and attention to maintain its seasoning and prevent rusting. The dishwasher's harsh detergents, high temperatures, and agitation can strip away the protective seasoning layer on the cast iron, causing it to rust and potentially damaging the pan.
To clean uncoated cast iron, it is best to use a gentle cleaning method. Here's how you can clean it by hand:
Allow the cast iron to cool: After cooking, let the cast iron cool down completely before cleaning.
Hand wash with minimal water: Rinse the cast iron with hot water and use a soft brush or sponge to remove any food residue. Avoid using soap as it can strip away the seasoning. Use minimal water to prevent prolonged exposure to moisture.
Remove stuck-on food: For stubborn or stuck-on food, you can use a non-metal scrub brush or a plastic scraper to gently remove it. Avoid using abrasive materials or harsh cleaning agents that can damage the cast iron surface.
Dry thoroughly: After washing, immediately dry the cast iron with a towel. Make sure to remove all moisture to prevent rust formation.
Apply a thin layer of oil: Once the cast iron is dry, apply a thin layer of oil (such as vegetable oil or shortening) to the surface. This helps to maintain the seasoning and protect the cast iron from rust. Wipe off any excess oil with a paper towel.
By following these steps, you can keep your uncoated cast iron in good condition and preserve its non-stick properties. Remember to store your cast iron in a dry place to prevent moisture from causing rust.
