Your Cast Iron Isn't Ruined. Here's How to Bring It Back, and Keep It Slick.

A well-kept cast iron pan can outlast the person who bought it. The rules people pass around can make it sound delicate, but the routine is short: clean it, dry it completely, and give it a thin coat of oil.

Cleaning after cooking

Clean the pan while it is still warm. Hot water and a brush or scraper handle most messes. A small amount of mild dish soap is fine on a seasoned pan; modern soaps will not strip seasoning the way old lye soaps could. What does damage cast iron is soaking it for hours or putting it in the dishwasher, so skip both.

For stuck-on food, add a spoonful of coarse salt and scrub with a folded paper towel, then rinse.

Dry it all the way

Water is the real enemy, because it leads to rust. Towel the pan dry, then set it on a burner over low heat for a minute or two until every trace of moisture is gone.

A thin coat of oil

While the pan is still warm, rub in a few drops of neutral oil with a paper towel, then wipe it again as if you were trying to remove it all. A heavy coat turns sticky. The goal is a sheen, not a film.

Cook with it often

The best seasoning comes from use. Searing, roasting and shallow frying all build up the dark, slick surface over time. Very acidic dishes simmered for a long time, like tomato sauce, can wear seasoning down on a newer pan, so save those for once the surface is well established.

If rust shows up

Rust is not the end. Scrub the spot down to bare metal with steel wool, wash, dry on the stove, then rub a thin layer of oil over the whole pan, inside and out. Bake it upside down in a hot oven for about an hour and let it cool inside. Repeat once or twice if the surface still looks dull.

Storage

Store the pan dry, somewhere with airflow. If you stack other pans inside it, a paper towel or pan protector between them prevents scratches and soaks up any humidity.
