Ultimate Guide: How to Remove Seasoning from Cast Iron

Cast iron cookware has been a longstanding favorite among home cooks, thanks to its durability and ability to retain heat. However, one downside of using cast iron is that over time, the seasoning that helps keep food from sticking can wear off. If you’re struggling with this issue, it’s important to know how to remove seasoning from cast iron and re-season it properly.

Why Remove Seasoning?

So, why would you want to remove the seasoning on your cast iron cookware? Here are a few reasons:

  • Your cast iron has become sticky or develops rust spots.
  • You want to start from scratch with a fresh seasoning layer.
  • You’re experiencing an off-flavor in your food.

Whatever the reason, removing the seasoning from your cast iron is a relatively simple process that won’t take up too much time.

How to Remove Seasoning from Cast Iron

If you’re ready to start fresh with your cast iron cookware, here are the steps you’ll need to follow to remove the seasoning:

  1. Preheat your oven to 400 degrees Fahrenheit.
  2. Place your cast iron cookware in the oven upside down.
  3. Let it bake for an hour.
  4. Turn off the oven and let the cast iron cool completely.
  5. Once it has cooled, use a scouring pad or steel wool to scrub off the seasoning.
  6. Rinse the cast iron thoroughly with warm water and dry it off completely with a clean towel.

That’s all there is to it! Your cast iron should now be free of old seasoning.

Re-Seasoning Your Cast Iron

Now that your cast iron has been stripped of its seasoning, it’s time to re-season it. Here’s how:

  1. Preheat your oven to 350 degrees Fahrenheit.
  2. Apply a thin layer of oil to the surface of your cast iron cookware.
  3. Place the cookware upside down in the oven and bake for one hour.
  4. After an hour, turn off the oven and let the cast iron cool in the oven.

That’s it! Your cast iron should now have a fresh seasoning layer and be ready for use again.

Tips for Keeping Your Cast Iron Seasoned

If you want to prevent your cast iron from losing its seasoning in the future, here are a few tips to keep in mind:

  • Always dry your cast iron cookware thoroughly after washing it.
  • Never leave your cast iron cookware to air dry, as this can cause rust to form.
  • Refrain from using soap on your cast iron cookware unless it’s absolutely necessary, as it can strip the seasoning.
  • Avoid soaking your cast iron cookware in water for extended periods of time, as this can cause rust to form.
  • When cooking with acidic foods like tomatoes, try to use another type of cookware instead of cast iron.


Cast iron cookware is a kitchen staple, but it does require some maintenance to keep it in top condition. Removing the seasoning from your cast iron and re-seasoning it properly is an easy process that will help keep your cookware in great shape for years to come.
