There is nothing like creating a kitchen concoction using a cast iron skillet. The naturally non-stick surface makes cooking with this material a dream, while the ability to take your pan straight from the stovetop to the oven or vice versa provides a freedom you can’t find in many other kitchen items. Add into that an evenly heating cooking surface, and you can see why there has recently been an increase in the popularity of cast iron.

While many believe a solid cast iron skillet requires more attention and care than the average non-stick or stainless steel pan, the reality is that looking after an all-metal pan is surprisingly easy, if done correctly. Just remember, you shouldn’t use harsh soap or steel wool to clean cast iron. It won’t ruin the pan, but it will take away the seasoned element of your skillet. Below, we’ll run through how not to clean cast iron as well as the instructions for properly washing and restoring cast iron cookware.

How NOT to Clean Cast Iron

Before we dive into how to properly wash and restore your cast iron, let’s first talk about what you should never do to a cast iron pot or pan. There are a few big no-nos to watch out for.

  • Never soak cast iron – Because cast iron can rust, it’s important to keep it as dry as possible. This means you shouldn’t leave it in water to remove stuck-on food. And, you should never leave food in the pan, either.
  • Never use steel wool – Steel wool or metal scrubbers can strip cast iron of its seasoning and leave it susceptible to rust. Instead, look for cast iron-safe scrapers or chainmail scrubbers to do the hard work.
  • Never put cast iron in the dishwasher – The dishwasher can strip cast iron of its seasoning and cause rust. Therefore, it’s necessary to always wash cast iron by hand.

Notice that we didn’t say, “Never use soap.” This is a really common misconception with cast iron. Yes, you can use a small amount of mild soap to clean your pots and pans. However, harsh soaps or even large amounts of mild soap can strip the seasoning off cast iron. Therefore, if you are going to use soap, be sure to do so sparingly and carefully.

How to Clean Cast Iron Properly

Now that we’ve covered what not to do with cast iron, it’s time to outline the steps for properly cleaning your cookware after each use. Once you know how to clean cast iron, the process will become as second nature as washing any dish.

  • 1. Wash – Begin by washing with water and a cast iron-friendly scrub brush.
    a.) If this doesn’t do the trick, add a small amount of mild soap.
    b.) And, if that doesn’t work to get all the stuck-on food off, try simmering a little water in the pan for about five minutes, and then using a flat, cast iron-safe scraper to remove all the bits.
    c.) For really stubborn food, you can also use a covering of kosher salt and a kitchen towel to scour the pan.
  • 2. Dry – Because cast iron is susceptible to rust, you’ll want to dry it promptly and thoroughly. Use a lint-free cloth or paper towel.
  • 3. Protect – To maintain the seasoning on your cast iron, it’s a good idea to coat your pots and pans with a thin layer of oil before storing it away in your cabinets. To do this, add a few drops of oil to a paper towel. Then, rub the paper towel on all the cast iron surfaces. Finally, use a clean paper towel to clean any excess oil from the metal.
    a.) Alternatively, you can use seasoning spray to coat the metal.

If for some reason, you can’t or don’t follow the proper steps for cleaning cast iron after use, don’t despair. You can easily restore rusty cast iron or reapply the seasoning. Read on for more information.

How to Restore Rusty or Stripped Cast Iron

Accidents happen, and if your cast iron has been stripped of its seasoning, you’ll need to work a little bit to get your cookware back in tip-top condition. First of all, note that if your cookware is showing only a little rust, all you need to do is scour the rust and then follow the directions outlined above to finish the cleaning process. But, if the rust problem persists or if you have a major amount of rust on your pan, follow the steps below for re-seasoning your cast iron.

  • 1. Scour – Using steel wool and warm, soapy water, scour your cast iron to remove the rust and the seasoning.
  • 2. Oil – Add a small layer of cooking oil, like vegetable or canola oil, to the pan. You can also use a cast iron conditioner here. Make sure the oil covers both the inside and the outside of the cookware, but don’t use too much. A thick layer of oil could create a gummy mess.
  • 3. Bake – Put your oil-covered cookware upside down on the top rack of your oven. Place a baking sheet on the bottom rack to catch any falling oil. Bake the cookware at 500 degrees Fahrenheit for one hour.
  • 4. Cool & Repeat – Allow the cookware to cool, then repeat steps two and three as necessary until you achieve the classic cast iron shine.

It’s important to remember that you’ll naturally need to re-season cast iron two to three times a year. Otherwise, cleaning and maintaining cast iron really isn’t as labor-intensive as its reputation might suggest.

We’ve put together a list of 16 great cleaning supplies for keeping your cast iron in top condition. All of them are available for under $40, so there’s really no excuse for improperly cleaning your skillet.

2. Happy Belly Vegetable Oil

BEST FOR SEASONING

As we mentioned above, it’s a good idea to add a thin layer of oil to your cast iron pots and pans after they’re clean and before you put them back in the cabinet. Vegetable oil is recommended for this process thanks to its high smoke point, affordability and availability, but canola oil, flaxseed oil and melted shortening can also be used. Simply put a few drops on a paper towel and cover your cast iron. Wipe away any excess with a clean paper towel, as a thick coating of oil will result in a gummy mess.

3. AIDEA Microfiber Cleaning Cloths

BEST FOR DRYING

Because cast iron is such a sensitive material, you need a drying cloth that’s not going to leave anything behind. That’s why we recommend only using lint-free cleaning cloths to dry your pots and pans, like the AIDEA Microfiber Cleaning Cloths. Microfiber is a great choice as it’s soft on metal and provides a streak-free clean. If you don’t have anything lint-free to hand, you could also use paper towel. Just be sure you don’t leave any paper fibers on the cast iron.

The bristles are intentionally firmer than average cleaning brushes, allowing you to clean your skillet without the use of harsh chemicals.

5. Diamond Crystal Kosher Salt

BEST HACK

If you have food stuck on your cast iron that you can’t seem to get off, salt may be the answer. Simply pour about one cup of kosher salt into your warm pan. Then, use a kitchen towel to scour away the stuck-on bits. Finally, pour the salt into the trash can and rinse the cast iron pan with hot water. The benefit to this method is that it’s not only safe for your cast iron, but it’s also fairly cost-effective, too.

9. Knapp Made Cast Iron Seasoning and Conditioner

BEST CONDITIONER

Much like your hair, cast iron also needs to be conditioned from time to time. Actually, a cast iron skillet should be re-seasoned two or three times a year, depending on how much you use it. When it’s time to do so, Knapp Made Cast Iron Seasoning and Conditioner can come in handy. Most of the time, seasoning cast iron means slathering your metal with oil, but the Knapp Made Cast Iron Seasoning and Conditioner makes the process far less messy. The mix of beeswax, canola oil and grapeseed oil goes on like butter, and once the pan is properly baked, this mix creates a lovely non-stick layer. Between seasonings, you can also use this wax-like substance to protect your cast iron after drying it.

10. Earlywood Handmade Wood Cooking Utensil

BEST SCRAPER

If a scrubber or cast iron brush won’t remove the food residue in your cast iron and you’re not ready to resort to salt, it’s time to break out the scraper. For stubborn, stuck-on bits, simmer a bit of water in the pan for three to five minutes. Then, after the pan has cooled, use a cast-iron safe scraper, like this Earlywood Cooking Utensil, to power through the remaining leftovers. You may already have a wooden spatula at home that would work, but this flat and slightly angled wooden utensil will make the scraping process easier.

11. Dapple Baby, Bottle and Dish Soap

BEST SOAP

There’s a giant misconception that you can’t use soap on cast iron. Yes, using harsh soap or a lot of soap will strip the seasoning. But, you CAN use a small amount of mild soap to clean your metalware. We recommend picking baby dish soap for this purpose, but really any mild soap will do. Simply put a tiny bit of soap on a cast iron-friendly brush and scrub your pan as you would a normal dish. Just be warned that if you use too much, you will need to re-season your cast iron.

12. Bounty Quick-Size Paper Towels

BEST MULTI-USE

After you’ve washed and dried your cast iron, you’ll need to seal it with a small layer of oil. The best way to do this is to put a few drops of vegetable oil on a paper towel and rub it onto the cast iron. Paper towels can also be used to dry cast iron when a lint-free towel isn’t available. And, as an added bonus, Bounty is useful for all other types of kitchen jobs, from cleaning up messes to washing the windows.
