Caring for Your Cast Iron So It Outlives You

A well-seasoned cast iron pan is not fragile -- it is one of the most forgiving tools you will ever own.

The biggest myth about cast iron is that it cannot get wet, and it scares people away from a pan that is genuinely hard to ruin. You can absolutely wash cast iron with a little soap and warm water; what you want to avoid is letting it soak or sit wet, because that invites rust. After cooking, scrub away any stuck bits with a stiff brush or a chainmail scrubber, rinse, and move on. The seasoning is a bonded layer of polymerized oil, not a coating of grease, so a quick wash will not strip it.

Drying is the step that actually protects your pan. Towel it off and then set it over low heat for a minute or two until every trace of moisture is gone, because even a thin film of water left in the pores will start rust within hours. Once it is bone dry and still warm, wipe a few drops of a neutral oil across the cooking surface with a paper towel until it looks barely sheened, not greasy. That habit, repeated after every use, is what builds a slick, dark, naturally non-stick surface over time.

If rust or sticky patches do appear, do not panic and do not throw the pan out. Scrub the trouble spots back to bare metal, wash and dry the pan completely, then re-season it by baking it upside down with a thin coat of oil at a high temperature for an hour. A pan that looks ruined today can be cooking eggs again by the weekend. Treated this way, a single skillet will pass through generations of cooks and only get better.
