How do you clean a cast iron skillet without ruining it?

Cleaning cast iron is straightforward once you know the main rule: avoid the dishwasher and long soaks, as both can lead to rust.

Here is the best way to keep your skillet in great shape:

1. Clean it while it's still warm It is easiest to clean the pan while it is still slightly warm from cooking. Rinse it under warm water. If there are stuck-on bits, use a stiff brush, a chainmail scrubber, or a plastic scraper.

2. Use a little soap (it’s okay!) Contrary to the old myth, a small drop of mild dish soap will not ruin your seasoning. It helps remove leftover grease and food particles. Avoid harsh chemicals or scouring pads that could strip the seasoning.

3. Dry it immediately and thoroughly Never let your cast iron air dry, as this is the fastest way to get rust. After rinsing, wipe it dry with a towel. To ensure it is completely moisture-free, place it on the stove over low heat for a minute or two until any remaining water evaporates.

4. Apply a light layer of oil Once the pan is dry and still slightly warm, use a paper towel to rub a very thin layer of neutral cooking oil (like grapeseed or vegetable oil) over the entire surface—inside, outside, and the handle. Wipe away any excess oil so the pan isn’t sticky. This prevents rust and maintains the non-stick finish.

If you find rust: Don't worry, the pan isn't ruined. Use a piece of fine steel wool to gently scrub away the rust until you reach bare metal, wash it, and then perform a fresh round of seasoning by baking it in the oven with a thin coat of oil.
