The best way to clean cast-iron cookware takes a bit more care than your standard nonstick or stainless steel pan. Cast iron is tough as nails, able to withstand scorching heat, the trash of metal utensils and years of banging around an oven range or grill top, but this rugged cookware material has a sensitive side. Along with seasoning your cast-iron skillet, cleaning cast-iron cookware properly will ensure your best skillet sees a long and productive life.
Cast iron is useful all year, but it really shines in cold winter months when the grill is put away until next spring. We love cast iron for its ability to sear the holy heck out of meats and veggies, but a good hot sear can sometimes leave a scorched pan in its wake. To properly and safely clean cast iron, you’ll want to avoid harsh soaps and use a more natural cleansing agent.
Whatever you do, resist the urge to soak your cast iron or run it through the dishwasher. For really stuck-on bits, a simple pantry staple will have your skillet looking better than new.
Give up? It’s salt.
Should you put cast-iron cookware in the dishwasher?
Wondering if cast iron is dishwasher-safe? The answer is complicated, but mostly it’s not. While a spin through the dishwasher won’t completely ruin the pan or render it useless, it will strip that important layer of seasoning and nonstick patina from the surface that you’re working to build over time. In short: It won’t do the pan any favors.
How to clean your cast-iron skillet like a pro
It doesn’t take more than a few minutes to clean a cast-iron pan. You also don’t need to give your pan a full, deep clean after every use. If you’ve only fried an egg or reheated some chick breast, for instance, a rag soaked in warm water is likely all you’ll need to wipe it clean.
But if you’ve just seared something with excess grease or there are stuck-on bits of food hanging out, follow these simple steps and your cast iron will stay clean and continue to hold that beautifully seasoned, nonstick surface.
Clean your cast-iron skillet while it’s still warm
I know — that sizzling pork chop is out of the pan and ready to eat and the last thing you want to do is clean. But, trust me, acting fast will make the job easier. Add warm water to the skillet a few minutes after removing it from the heat while it’s still warm — but not scorching hot or you might warp the metal. That quick simmer will go a long way in degunking the pan.

Use salt to clean cast iron for stubborn, stuck-on foods
From a glance at your skillet, you should be able to tell what kind of cleaning task you have on your hands. After most uses, a dousing of warm water should do the trick. But if things are extra sticky, sprinkle the cast iron with a bit of kosher salt (without water) and scrape it gently with a flat-ended wooden spoon or spatula. Dump the salt and add some water to get things moving.

Can you use dish soap on cast iron?
The No. 1 cast-iron cookware cleaning question is whether or not you can use soap to clean a skillet or grill pan. The answer is yes, but you should try not to. A little bit of soap — I mean a real small dab — won’t ruin your cast iron, but certain harsh soaps will erode the nonstick patina and could also affect the flavor your cast iron has developed.
