How to clean a cast iron skillet?

Cast iron skillets are not only inexpensive and versatile, they will also last for generations! Cast iron can unfortunately rust or even burn, so it must be well maintained and cleaned.
You don’t care for a cast iron skillet the same way you care for an aluminum skillet. In order to enjoy your cast iron skillet for a long time, follow our advice on how to clean and maintain your cast iron skillet.
Before you even use your brand new cast iron skillet, you will need to prepare it, season it to ensure its longevity and prevent rust from appearing on its surface. This is done by creating a hard, protective coating by heating thin layers of fat (like oil) on the cast iron. As the fat is heated, it bonds to the metal in a process called polymerization: the fat turns into a form of plastic.
After applying enough coats of oil, not a greasy coating but a hard, blackened skin will form and protect the metal of the pan. This will also bring non-stick properties to your pan, which makes even the most stick-prone foods (think fried eggs) a pleasure to cook with cast iron.
Here are the steps for seasoning a cast iron skillet:
- Wash the pan with dish soap and a sponge, then dry well.
- Coat it with vegetable oil, inside and out, including the handle.
- Heat it in an oven at 230 degrees Celsius for 30 minutes.
- Repeat 3 or 4 times: take the pan out of the oven, coat it again with oil and put it back in the oven.
After each use, you will need to maintain your cast iron skillet to ensure its longevity. To do this, you will need vegetable oil, salt and paper towels.
- Pour two tablespoons of oil in the bottom of the pan, then put the pan on the fire and let it heat for a few minutes.
- Then, turn off the heat, and pour 3 tablespoons of salt. Roll the paper towel into a big ball, and rub well all over.
- Once done, rinse the pan under running water, and dry well.
- Finally, apply another thin layer of oil.
If you follow all the above steps correctly, your cast iron skillet will remain in good condition for a very long time.
