That’s why I’m here to help you learn how to wash and clean your cast iron pan without damaging it, so you can keep cooking up delicious meals for years to come.
Let’s dive into some useful tips, personal experiences, and practical advice to make cleaning your cast iron a breeze!
How to Wash and Clean a Cast Iron Pan
Cleaning your cast iron pan after each use is essential for maintaining its performance and longevity.
Here’s a step-by-step guide for you to follow:
Step 1: Let the Pan Cool Down
After cooking, allow the pan to cool down to a warm (not hot) temperature.
Handling a hot pan can be dangerous, and immersing it in cold water could cause thermal shock, potentially leading to cracks or warping.
Step 2: Remove Excess Food
Using a paper towel, silicone spatula, or a non-abrasive scrubber, gently remove any leftover food particles from the pan.
For larger, stuck-on pieces, you can try using the edge of a wooden spoon or spatula to carefully lift them off without scratching the pan’s surface.
Step 3: Rinse with Water
Hold the pan under running warm water and gently scrub it with a soft sponge, cloth, or a nylon brush specifically designed for cast iron.
Avoid using soap, as it can strip the seasoning from the pan.
However, if your pan is well-seasoned, using a small amount of mild soap shouldn’t cause any significant harm. Just be sure to rinse it off thoroughly.
Step 4: Tackle Stubborn Residues
If you still have stubborn, stuck-on food residue after rinsing, try these methods:
Deglaze with hot water: Add a small amount of hot water to the pan while it’s still on the stovetop. This will help to loosen the stuck-on food. Gently scrape with a wooden spatula as the water simmers for a couple of minutes. Then, pour out the water and rinse the pan.
Use a chainmail scrubber: A chainmail scrubber is an excellent tool for cleaning cast iron pans without damaging their seasoning. Gently scrub the stubborn residue with the chainmail scrubber under running water until the debris is removed.
Step 5: Dry the Pan
Immediately dry the pan thoroughly with a clean towel or a paper towel to prevent rust.
You can also place it back on the stovetop on low heat for a couple of minutes to evaporate any remaining moisture.
This step is crucial, as excess moisture can lead to rust.
Step 6: Oil the Pan
Apply a thin layer of cooking oil (like vegetable oil, flaxseed oil, or even shortening) to the pan’s surface with a paper towel or a soft cloth.
This step will help maintain the seasoning and protect the pan from rust. Make sure to cover the entire surface, including the handle and the bottom of the pan.
Dealing with Stubborn Residue on a Cast Iron Pan
Sometimes you might encounter stubborn, stuck-on food that just won’t budge. Don’t worry; there are several effective techniques to help you tackle these challenging spots.
Here are some of my favorite techniques to remove stubborn residue:
Use Coarse Salt
Coarse salt can work wonders when it comes to removing stubborn residue from your cast iron pan:
Sprinkle salt: Sprinkle a generous amount of coarse salt (like kosher salt or sea salt) onto the pan’s surface.
Scrub gently: Use a damp sponge, cloth, or a non-abrasive scrubber to gently scrub the pan in a circular motion. The abrasive action of the salt will help break up the residue without damaging the pan’s surface.
Rinse and dry: Rinse the salt and debris off the pan under running water and dry it thoroughly.
Boil Water in the Pan
Boiling water in your cast iron pan can help loosen stubborn residue:
Add water: Fill the pan with a thin layer of water – just enough to cover the affected area.
Bring to a boil: Place the pan on the stovetop and bring the water to a boil.
Scrape gently: Use a spatula or a wooden spoon to gently scrape the debris off the pan as the water boils. Be careful not to scratch the pan’s surface.
Rinse and dry: Carefully pour out the hot water, rinse the pan under running water, and dry it completely.
Use a Potato and Baking Soda
This unconventional method can help remove stubborn residue without damaging your cast iron pan:
Cut a potato: Slice a raw potato in half, ensuring that you have a flat surface to work with.
Dip in baking soda: Dip the cut side of the potato in baking soda. The baking soda will act as a gentle abrasive.
Scrub the pan: Use the potato to scrub the stubborn residue in a circular motion. The combination of the potato’s moisture and the baking soda’s abrasive properties should help break up and remove the stuck-on food.
Rinse and dry: Rinse the pan under running water to remove the baking soda and debris, and then dry it thoroughly.
Please note: You may have to combine two or more of the techniques above to get rid of really tough food residue.
How to Remove and Clean Rust from a Cast Iron Pan
Rust can sometimes form on cast iron pans, especially if they’re not dried and oiled properly. If you spot some rust, don’t worry!
