How to Clean a Cast Iron Skillet
Clean your skillet while it is still warm to the touch by scrubbing it with a stiff brush and hot water, then immediately dry it completely over a low flame and rub it with a very thin layer of high-smoke-point oil. Never soak it in water and skip the soap unless you are dealing with a significant mess, as consistent heat and oil are the only things keeping your seasoning intact.
Commit to the post-cook habit.
The best maintenance happens immediately after you serve, while the iron is still warm enough to prevent moisture from sinking into the surface.
- stiff-bristled brush or chainmail scrubber
- lint-free cloth or paper towels
- stove burner
- neutral cooking oil
Evaporate every drop
Air drying leaves rust; stove drying ensures the iron stays bone-dry. Always return the damp pan to a low burner for two minutes until the surface looks matte and thirsty.
The method.
Scrub the warm surface
Use a stiff-bristled brush under hot running water to dislodge stuck-on bits. If food is fused to the pan, use a chainmail scrubber; it removes stubborn carbon without stripping the polymerized layer.
Dry on the stove
Place the cleaned skillet on a burner over low heat. Once the water has evaporated and the pan feels completely dry, turn off the heat.
Apply the oil barrier
Pour a half-teaspoon of neutral oil into the warm pan. Use a paper towel to buff the oil across the entire interior surface until the pan looks dark and satin-smooth, then wipe away any excess so it does not become tacky.
When it doesn't go to plan.
If you accidentally used soap, simply skip the seasoning step and do an extra round of oiling to build back the layer.
For stubborn burnt-on patches, boil a small amount of water in the skillet for two minutes, scrape with a wooden spatula, then proceed with the standard cleaning.
If the pan looks grey or chalky, it has lost its seasoning; it needs to be wiped with oil and heated in an oven to restore the surface.

Can I use soap?
Modern mild dish soaps are not caustic enough to strip modern seasoning, but they are unnecessary. A good scrub with hot water is almost always enough.
What should I do if I see rust?
Scour the rusted area with steel wool until the bright iron shows, wash it, dry it immediately, and re-season it in the oven.
