7 Quick Steps to Clean Your Cast Iron Skillet

Cleaning a cast iron skillet isn’t like cleaning your regular pots and pans. While those can usually handle soap and a trip through the dishwasher, cast iron requires a little more TLC. The seasoning (a lovely layer of baked-in oil) gives it that non-stick surface and rich flavor, and we want to keep that intact! So, here’s how you do it!

1. Cool Down After Cooking

Let your skillet cool down after you’ve whipped up something delicious. But don’t wait too long—cleaning it while it’s still warm makes the job easier! A hot skillet helps loosen food bits, making the cleaning process smoother.

2. Scrape Off Food Residue

Using a spatula or a stiff-bristle brush, gently scrape away any food bits stuck to the surface. Avoid metal scrubbers, as they can scratch the seasoning. For those stubborn bits that won’t budge, a plastic scraper or wooden spoon does wonders without causing damage.

3. Rinse with Warm Water

Now it’s time for a rinse! Hold your skillet under warm water. You can use a tiny drop of mild dish soap if stubborn residues remain. While some cast iron enthusiasts argue against soap, a little won’t harm a well-seasoned skillet. Just be sure to rinse thoroughly to remove any soap residue.

4. Use Salt for Stubborn Residues

If you encounter pesky, stuck-on food, grab some coarse kosher salt and mix it with a bit of water to create a paste. Apply this paste to the affected areas and scrub with a non-abrasive sponge. The salt is a gentle abrasive, helping lift off food without damaging the skillet’s seasoning.

5. Dry Immediately

Once you’re done rinsing, it’s crucial to dry your skillet right away! Use a clean towel to wipe it down thoroughly. Leaving it wet can lead to rust, which we want to avoid. For extra assurance, pop it on a low burner for a few minutes to evaporate any remaining moisture.

6. Re-season Your Skillet

Applying a light coat of vegetable oil or your favorite cooking fat is a great way to keep your skillet in tip-top shape while it’s still warm. Use a paper towel to spread it evenly over the surface. This little step helps protect the skillet from moisture and enhances its non-stick properties.

7. Store Properly

When it’s time to store your skillet, find a dry place. If you stack it with other cookware, place a paper towel or cloth between them to absorb moisture and avoid scratches.

Pro tip: Some folks even toss a few rice grains in the skillet to help prevent moisture from escaping.

Now that you know how to clean your cast iron like a pro, here’s how to season it!

Step 1: Clean Your Skillet

Start by scrubbing your skillet with warm water and mild dish soap to remove old seasoning, dirt, or debris. Use a scrub brush or sponge for tough spots. Rinse thoroughly and dry completely with a clean cloth or paper towel.

Step 2: Apply Oil

Once the skillet is dry, apply a thin layer of your chosen cooking oil. Use a paper towel or cloth to rub the oil into the entire surface, including the interior, exterior, and handle. Wipe away excess oil—too much can result in a sticky finish.

Step 3: Add Aromatics (Optional)

For added flavor, sprinkle a thin layer of coarse salt and crushed garlic (or garlic powder) on the oiled surface. Rub it in gently—this will not only season the skillet but also impart subtle garlic flavor to your cooking.

Step 4: Preheat Your Oven

Preheat your oven to 450°F (232°C). This high temperature will help the oil bond with the cast iron, creating a durable non-stick layer.

Step 5: Bake the Skillet

Place a piece of aluminum foil on the bottom rack of your oven to catch any drips. Then, place your oiled skillet upside down on the top rack. Bake for 1 hour to allow the oil to polymerize and the flavors to infuse.

Step 6: Cool Down

After an hour, turn off the oven and let the skillet cool inside. This gradual cooling process helps prevent cracking and warping.

Step 7: Repeat (Optional)

For an even better non-stick surface, consider repeating the oil and aromatics application and baking process 2-3 times. Each layer builds up the seasoning and flavor.

Cast Iron FAQs

As you embrace the joys of cooking with your cast iron skillet, you might have questions about its care and maintenance. Below are some common inquiries that many cast iron enthusiasts have. Let’s clear up any confusion and help you make the most of your beloved skillet!

Why Do Cast Iron Skillets Need Special Care?

Cast iron skillets need special care primarily to maintain their seasoning, which creates a natural, non-stick surface and enhances cooking performance. The seasoning can wear away without proper maintenance, leading to rust and food sticking.

Additionally, cast iron is prone to moisture damage, so thorough drying after washing is essential to prevent rust formation. Treating your skillet carefully ensures its longevity, preserving the flavors it develops over time and keeping it ready for countless delicious meals.

What Is Skillet Seasoning and Why Is It Important?

Seasoning a cast iron skillet is crucial because it provides a natural, non-stick surface and adds flavor to your dishes. This layer is built up over time by heating oil and allowing it to bond to the iron. Proper cleaning and maintenance will help preserve this seasoning, ensuring your skillet performs beautifully with every use.

How Can You Prevent a Cast Iron Skillet from Rusting?

If you spot rust, don’t panic! You can often scrub it away with a mix of baking soda and water or even with steel wool. Once you’ve removed the rust, don’t forget to re-season your skillet to restore that protective layer.

How Do You Prevent Food from Sticking to Cast Iron Skillet?

If food starts sticking, it might be a sign that the seasoning needs a refresh. Scrub the skillet clean, dry it well, and re-season it with a thin layer of oil to restore its non-stick surface. This will make cooking and cleaning a breeze!

How Do You Get Rid of Odors or Flavors on Cast Iron Skillet?

If your skillet is holding onto odors from previous meals, scrub it well with salt and rinse thoroughly. Then, re-season it to lock in freshness! A well-cared-for skillet should impart delicious flavors, not unwanted odors.

Can You Soak a Cast Iron Skillet?

No! It’s never a good idea to soak your cast iron skillet in water—this can lead to rust and damage.

Can You Put a Cast Iron Skillet in the Dishwasher?

Dishwashers and cast iron are enemies. The heat and harsh detergents can ruin the seasoning and lead to rusting.

What Do You Do When a Cast Iron Skillet Is Rusting?

If your cast iron skillet is rusting, scrub off the rust with a steel wool pad or stiff brush, using a vinegar and water mixture for tougher spots. Next, wash it with warm soapy water, rinse thoroughly, and dry completely. Apply a thin layer of vegetable oil or shortening to the skillet, then bake it upside down in a preheated oven at 350°F (175°C) for about an hour, using a baking sheet to catch drips.

PSA: To prevent future rust, always dry the skillet immediately after washing and apply a light coat of oil before storing. Your skillet will be restored and ready to use!
