Cast iron and dishwashers? Nope! That’s a recipe for disaster. If you’ve ever wondered, “Can I just toss my cast iron skillet in the dishwasher?”—the answer is a big NO (unless you enjoy rust and ruined seasoning). But don’t worry, I’ve got you covered with the right way to clean your cast iron properly.
Why You Should NEVER Put Cast Iron in the Dishwasher
Dishwashers use harsh detergents, high heat, and prolonged moisture, all of which spell doom for your cast iron. Here’s what happens:
- Rust, rust, and more rust – Water exposure strips the seasoning and causes oxidation.
- Destroyed seasoning – That beautiful non-stick layer you’ve built up? Gone.
- A sad, rough surface – The detergents are too aggressive and can leave your skillet feeling gritty.
How to Properly Wash Cast Iron
Now that we’ve agreed the dishwasher is off-limits, let’s go over the right way to clean your cast iron:
1. Clean Immediately After Use
Once you’re done cooking, don’t let food sit for hours. While the pan is still warm (but not scorching hot), move on to the next step.
2. Skip the Soap (Mostly)
For light cleaning, use hot water and a scrub brush or chainmail scrubber. If you have stubborn bits stuck, sprinkle some coarse salt, scrub, and rinse. A tiny drop of mild dish soap is okay occasionally, but avoid soaking!
3. Dry It COMPLETELY
Towel-dry it first, then place it on low heat on the stovetop for a minute to ensure all moisture is gone.
4. Re-Season the Pan
Once dry, rub a thin layer of oil (like flaxseed or vegetable oil) all over the surface. Heat it until the oil is absorbed. This keeps your cast iron in top shape.
What If You Already Put It in the Dishwasher?
Uh-oh. If your cast iron took an accidental trip through the dishwasher, don’t panic. Here’s how to save it:
- Scrub off rust using steel wool.
- Wash with hot water and dry completely.
- Re-season it by applying oil and baking it at 400°F (205°C) for an hour.
Final Thoughts
Your cast iron deserves better than the dishwasher. Treat it right, and it will reward you with a lifetime of perfect sears and crispy edges. Happy cooking!
