Made the mistake of putting cast iron in dishwasher. What do I do now? Is it ruined for good?

So you've accidentally put your cast iron cookware in the dishwasher, and now you're worried if the robust kitchen workhorse has met its doom. It's a common misconception that cast iron is indestructible, leading many to think it can survive a cycle in the automated beast that is the dishwasher. First and foremost, don't panic.

While cast iron ideally prefers a manual clean, all may not be lost. In this article, we'll delve into what to do if this mishap befalls you and how to restore your cookware to its former glory.

The primary reason cast iron should not go in the dishwasher is that the prolonged exposure to water and harsh detergents can strip away the seasoning – the oil baked onto the iron that protects it from rust and creates a non-stick surface. Moreover, the dishwashing process can lead to rusting, which, if left unchecked, can permanently damage the pan. But if the deed has been done, here is a strategic approach to assess and revive your cast iron cookware.

Start by taking a close look at your cookware. Is there rust? Has the seasoning been removed, leaving bare metal? Does it have a dull, gray appearance?

If rust is present, it's important to remove it to prevent further damage. You can do this with a scouring pad or steel wool. Gently scrub the rusted areas until the rust is gone. Some elbow grease will be required, but generally, this step can clear away superficial rust.

After de-rusting, wash the cookware by hand with warm water. It's crucial to avoid soap as it can further strip the seasoning. Instead, use a stiff brush or non-abrasive scrubber to clean the surface.

To prevent new rust from forming, dry your cast iron thoroughly with a clean towel. Then, place it on a stove over low heat for a few minutes to ensure all moisture is evaporated from both the inside and the outside, as well as from any crevices.

Re-seasoning is essential to restore the non-stick surface and protect it from future rust. Follow these steps to re-season:

1. Preheat your oven to 375°F (190°C).

2. Apply a very thin coat of cooking oil to the entire surface of your cookware, including the exterior and handle.

3. Place the cookware upside down on the middle rack of the oven to promote even seasoning.

4. Put a sheet of aluminum foil or a baking sheet on the bottom rack to catch any drips.

5. Bake the cookware for one hour.

6. After an hour, turn off the oven and let the cookware cool down inside the oven before removing it.

After re-seasoning, use and maintain your cast iron cookware properly to prevent future mishaps. Always hand wash with hot water and a stiff brush, dry completely, and apply a light coat of oil after each use.

While putting cast iron in the dishwasher is not recommended, it doesn't have to mean the end of your beloved cookware. With proper care and re-seasoning, you can bring it back to life. Remember that cast iron is resilient but benefits greatly from proper maintenance. By following the steps outlined above, you can continue to enjoy cooking with your cast iron for many years to come.
