Four Steps to Cleaning Cast Iron Cookware

Cooking with a cast iron skillet adds a timeless charm to your kitchen, creating meals that boast unparalleled flavor. With some extra care, they will remain a durable and reliable kitchen asset.

1. Wash with Care and Rinse Throughly

Cast iron skillets should be cleaned promptly after use. Use a soft sponge or scrubber brush, hot water, and mild dish soap to scrub away any food residues. Avoid using harsh abrasives or steel wool, as these can damage the seasoned surface. You can also look for a specific brush for cast iron.

Contrary to popular belief, it's perfectly acceptable to use mild soap when cleaning a cast iron pan, as long as it's done with care to avoid damaging the seasoned surface.

After scrubbing off the food bits, rinse the skillet under warm water. Make sure to remove all soap residue to maintain the integrity of the seasoning.

Payoff: Washing your cast iron skillet right after use prevents food particles from hardening and makes the cleaning process easier. Thorough rinsing ensures that no soap is left behind, preserving the natural flavors of your dishes.

2. Dry Immediately

Dry the entire surface of the skillet thoroughly using paper towels or a clean dry cloth. It's essential to prevent any moisture from lingering on the surface to avoid rusting.

Payoff: Immediate drying prevents rust formation, ensuring the longevity of your cast iron skillet.

3. Oil it Up

Apply a thin layer of cooking oil to the entire surface of the skillet, including the handle. Use a paper towel to spread the oil evenly and remove any excess.

Payoff: Adding a protective layer of oil helps maintain the skillet's seasoning and prevents it from drying out.

4. Heat it Up

Place the skillet on the stove over low heat for 3-5 minutes. This process, known as seasoning, helps the oil bond with the iron, creating a natural non-stick surface. Once the skillet has cooled in the oven or on a dish towel, store it in a dry place. Avoid stacking the cookware to prevent potential damage to the seasoning.

Payoff: Seasoning enhances the skillet's non-stick properties, making it easier to cook with and clean.

Remove Rust (If Necessary)

If you notice rust on your cast iron skillet, don't worry – it's fixable. To remove rust, create a paste by mixing equal parts of table salt and warm water. Gently scrub the rusted areas with a soft sponge or brush. The salt acts as a natural abrasive without harming the seasoning. Rinse and dry the skillet thoroughly, then proceed to the oiling and heating steps.

Payoff: Removing rust ensures your skillet stays in top condition, preserving its functionality and appearance. Regular maintenance helps prevent extensive rusting.

What Not to Do with Cast Iron Cookware

While this kind of cookware is robust and versatile, certain practices can compromise its durability and performance. Avoid these common pitfalls to ensure your skillet stays in optimal condition:

Avoid Abrasive Cleaners and Tools: Refrain from using harsh abrasives, steel wool, or metal brushes when cleaning your cookware. These can scratch and damage the seasoned surface, diminishing its non-stick properties.
Say No to Dishwashers: Never toss your iron cookware into the dishwasher. The high-pressure water and harsh detergents can strip away the seasoning and promote rusting. Stick to handwashing with mild dish soap and warm water.
Don't Soak for Extended Periods: Prolonged soaking can lead to rust formation. Instead, clean it promptly after use and dry it thoroughly to prevent moisture-related issues.
Avoid Extreme Temperature Changes: Rapid temperature changes, such as placing a hot skillet under cold water, can cause thermal shock and lead to cracking. Allow your cast iron to cool gradually before cleaning or storing.
Don't Skip Seasoning: Regular seasoning is crucial for maintaining the non-stick surface. Skipping this step can result in diminished performance and an increased risk of food sticking to the surface.
Refrain from Stacking Unseasoned Cast Iron: Avoid stacking multiple pieces without proper protection, especially if they are unseasoned. Direct contact can lead to scratching and damage to the seasoned layer.
