Keeping Your Cast Iron Useful
A well-maintained skillet turns deep black and slick, eventually becoming a non-stick surface you can rely on daily. Treat the metal like a living tool, not a delicate heirloom, and it will last for generations.
Consistency beats perfection.
The most important part of maintenance is the immediate reaction to cleanup. If you ignore the pan after a meal, rust will find it.
- Stiff-bristled brush
- Kosher salt
- Lint-free cloth or paper towels
- Neutral cooking oil (grapeseed or canola)
The Heat-Dry Method
Never air-dry cast iron. Always place your wet pan over a low burner for two minutes until the heat forces the moisture out of the microscopic pores of the iron.
The method.
Clean while warm
Wash the pan with hot water while it is still warm from the stove. Use a stiff brush for stuck bits; if something is truly stubborn, scrub it with a handful of kosher salt.
Dry completely
Wipe it with a cloth, then set it on a burner over low heat. Wait until the surface looks chalky and completely dry.
Apply the fat
While the pan is warm, add half a teaspoon of oil. Use a paper towel to buff it into every corner of the surface, then use a clean side of the towel to wipe away every trace of excess oil until it looks matte, not greasy.
When it doesn't go to plan.
If your food tastes like metallic soap, your seasoning is breaking down; scrub it clean and re-oil.
Avoid cooking highly acidic foods like tomato sauce in a freshly seasoned pan, as it can strip the protective layer.
The oil should be nearly invisible; if the pan feels sticky to the touch after heating, you used too much oil.

Can I use dish soap?
Yes, modern dish soap is mild and will not strip a well-established layer of seasoning. The bigger risk is leaving the pan submerged in water, not the soap itself.
How do I fix rust spots?
Scrub the rust off with steel wool until the bare grey metal shows. Wash, dry, and apply a very thin layer of oil, then bake it in a 450 degree oven for one hour.
