Removing melted plastic from a cast iron skillet can be a bit tricky, but it's possible with some careful steps. Here's a guide to help you clean the skillet without damaging its seasoning:
Safety first: Make sure the skillet is not hot and has cooled down completely before attempting to remove the melted plastic.
Freezing method: If the plastic has hardened, you can try freezing the skillet. Place the skillet in a freezer or use ice packs to chill the plastic. Once it's cold and brittle, you may be able to gently scrape the plastic off using a plastic or wooden utensil. Avoid using metal utensils to prevent scratching the cast iron surface.
Boiling water method: If the plastic is soft and gooey, you can try the boiling water method. Fill the skillet with enough water to cover the affected area and bring it to a boil on the stove. The heat should soften the plastic enough to allow you to scrape it off with a plastic or wooden utensil.
Scrubbing: For stubborn or small remnants of plastic, you can try scrubbing with a soft sponge or scrub brush. Be gentle to avoid damaging the seasoning.
Baking soda paste: If there are any residue or stains left, you can create a baking soda paste by mixing baking soda with a little water. Apply the paste to the affected area and let it sit for a few minutes. Then gently scrub with a soft sponge or cloth.
Re-seasoning: After removing the melted plastic and cleaning the skillet thoroughly, you may need to re-season the cast iron to restore its non-stick properties and protection against rust. To re-season, coat the skillet with a thin layer of vegetable oil or melted shortening and bake it upside down in an oven at 375°F (190°C) for about an hour. Let it cool completely before using it again.
Remember, patience and gentle cleaning methods are key when dealing with cast iron to avoid damaging the skillet's surface. If the plastic residue is extensive and challenging to remove, it's best to seek advice from a professional or consider contacting the manufacturer for guidance.
