Keeping Your Cast Iron Ready
Maintenance is a cycle of washing, drying, and heating. After use, scrub the pan with hot water and a stiff brush, dry it completely on a stovetop burner, and rub a thin layer of oil into the surface while it is still warm to prevent rust.
Consistency is your only friend here.
Don't let the pan sit in the sink or air-dry. Water is the enemy of iron, and moisture left behind is what causes pits and orange rust.

- Lint-free cotton cloth or paper towel
- Stovetop burner
- High smoke-point oil like grapeseed or flaxseed
Kill the moisture
Never rely on air-drying. Always place your washed pan over medium-low heat for three minutes until every microscopic drop of water has evaporated.
The method.
Clean while warm
Scrub the pan with hot water and a stiff brush as soon as it is cool enough to handle. Use a small amount of mild soap if necessary; it will not harm the seasoning.
Dry on heat
Place the pan on the stove over medium-low heat. Once the surface looks matte and dry, wait an additional minute to ensure the pores of the iron are fully dehydrated.
Apply oil
Add a few drops of oil. Use a rag or paper towel to buff the oil across the entire interior surface. The goal is to leave a layer so thin it looks dry, not greasy.
Heat to set
Keep the heat on for another two minutes until the oil just begins to smoke, then turn off the burner and let the pan cool completely before putting it away.
When it doesn't go to plan.
If food sticks, simmer water in the pan for two minutes to loosen the debris before scrubbing.
If you see a spot of rust, scour it with steel wool until the iron is exposed, then re-season by coating the area with oil and baking it at 450°F for an hour.
Store your pans with a paper towel between them if you stack them to prevent scratching the seasoning.
The ones that keep coming up.
Can I use soap?
Yes. Modern mild dish soap is fine. The old rule against soap came from the days when lye-based soaps could strip seasoning; today’s detergents are safe for iron.
How do I know if I need to re-season?
If the surface looks dull, gray, or food consistently sticks to the bottom, it is time for a full oven-seasoning session.
