A well-seasoned cast iron skillet is one of the hardest-working pieces of cookware you can own. With proper care, it can last for decades, or even become something you pass down to the next generation. Cast iron heats evenly, develops a naturally slick cooking surface over time, and only gets better with regular use.
The secret is knowing how to clean it without damaging that hard-earned seasoning. Most of the time, cleaning cast iron is much easier than people expect. The right method depends on what’s left in the pan, whether it’s a light coating of grease, stuck-on food, or a little surface rust.
Here are 15 ways to clean and care for your cast iron skillet, along with the best time to use each one.
1. Wipe It Clean With a Paper Towel or Cloth
Best for: Light grease and small food crumbs.
If the skillet isn’t very dirty, a quick wipe may be all it needs. While the pan is still warm, use a paper towel or a soft cloth to remove grease and loose bits of food. This keeps cleanup simple and leaves the seasoning undisturbed.
2. Rinse With Hot Water
Best for: Everyday cleanup.
For most meals, hot water is enough to clean your skillet. Let the pan cool for a few minutes, rinse it under hot running water, and scrub lightly with a soft sponge or dish brush. Dry it right away so moisture doesn’t have a chance to create rust.
3. Use a Plastic Scraper
Best for: Food that’s lightly stuck.
A plastic or silicone scraper can lift stubborn food without scratching the cooking surface. Scrape away any residue, rinse with hot water, then dry the skillet completely.
4. Scrub With Kosher Salt
Best for: Stuck-on food that needs a little extra help.
Coarse kosher salt acts as a gentle scrubber. Sprinkle a generous amount into the skillet, add a splash of water to make a rough paste, and scrub with a sponge or cloth. Once the food comes loose, rinse well and dry the pan.
5. Boil Water in the Skillet
Best for: Burned-on food.
Instead of scraping endlessly, pour about half a cup of water into the skillet and bring it to a gentle boil. As the water heats, use a wooden spoon or spatula to loosen the food. Empty the pan, rinse, and dry it thoroughly.
6. Try a Chainmail Scrubber
Best for: Tough residue that won’t come off easily.
Chainmail scrubbers are made for cast iron and remove stubborn food without stripping away healthy seasoning. Wet the skillet, scrub gently, rinse, dry, and finish with a light coat of oil.
7. Dry the Skillet Over Heat
Best for: Every time water is used.
Even a small amount of leftover moisture can lead to rust. After washing, place the skillet on the stove over low heat for a few minutes until it’s completely dry.
8. Rub on a Thin Coat of Oil
Best for: Regular maintenance.
Once the skillet is dry, add a few drops of cooking oil and spread it over the entire surface with a paper towel. Wipe away any excess so only a very thin layer remains. This helps protect the pan and keeps the seasoning in good shape.
9. Use a Little Dish Soap if Needed
Best for: Heavy grease or lingering odors.
Modern dish soap is much milder than older formulas, so using a small amount once in a while won’t ruin a well-seasoned skillet. Wash gently with a soft sponge, rinse well, dry completely, and finish with a light coating of oil.
10. Make a Baking Soda Paste
Best for: Strong odors.
If your skillet still smells like fish, garlic, or another strongly flavored food, mix baking soda with a little water to make a thick paste. Rub it over the cooking surface, scrub gently, rinse, dry, and apply a little oil afterward.
11. Scrub With a Potato and Salt
Best for: A natural scrubbing method.
Cut a potato in half, sprinkle coarse salt into the skillet, and scrub using the cut side of the potato. The salt loosens stuck food while the potato provides just enough moisture to help with cleaning. Rinse, dry, and oil the pan afterward.
12. Use a Cast Iron Cleaning Brush
Best for: Frequent cast iron cooking.
A brush made for cast iron has stiff bristles that remove food without damaging the seasoning. After rinsing the skillet with warm water, scrub away any residue, dry the pan well, and wipe on a thin coat of oil.
13. Re-Season the Skillet
Best for: A pan that’s losing its slick cooking surface.
If food starts sticking more than usual or the finish looks dull, it’s time to refresh the seasoning. Clean and dry the skillet, coat it lightly with oil inside and out, then place it upside down in a 350°F oven for about an hour. Put a sheet of foil on the rack below to catch any drips, then let the skillet cool inside the oven.
14. Remove Light Rust With Vinegar
Best for: Small patches of surface rust.
Mix equal parts white vinegar and water, then soak the rusty area for one to two hours. Scrub away the rust with a stiff brush or fine steel wool, rinse well, dry immediately, and re-season the skillet before using it again.
15. Use Steel Wool for Heavy Rust
Best for: Severe rust buildup.
If rust has spread across the skillet, fine steel wool may be your best option. Scrub until all the rust is gone and you’re back to clean bare iron. Wash the pan, dry it completely, and season it again before cooking.
A little routine care goes a long way with cast iron. Wipe it clean after each use, dry it thoroughly, and keep a light coating of oil on the surface. Do that consistently, and your skillet will be ready for everything from pancakes and cornbread to steaks and skillet dinners for many years to come.
