Removing burned-on baking sheet coating from cast iron skillets can be a bit challenging, but there are a few methods you can try. Here's a step-by-step process to help you remove the coating:
Scrub with a Stiff Brush: Start by scrubbing the surface of the cast iron skillet with a stiff-bristled brush or a non-metal scrubbing pad. This will help loosen and remove any loose or flaking coating.
Apply Vinegar: Pour a small amount of white vinegar onto the affected area. Vinegar is mildly acidic and can help break down stubborn residue. Let it sit for a few minutes to penetrate the coating.
Scrub with Salt or Baking Soda: Sprinkle a generous amount of salt or baking soda onto the vinegar-soaked area. Use a brush or scrubbing pad to scrub the surface gently. The abrasive nature of salt or baking soda will assist in removing the burned-on coating.
Create a Paste: If the previous step didn't completely remove the coating, you can make a paste by mixing baking soda and water. Apply the paste to the affected area and let it sit for a few minutes.
Scrub with Paste: Scrub the paste into the coating using a brush or scrubbing pad. The gentle abrasive action of the paste, combined with the chemical reaction, can help lift the residue.
Rinse and Dry: Once you have scrubbed the surface thoroughly, rinse the skillet with warm water to remove any remaining residue. Make sure to dry the skillet completely to prevent rust.
Season the Skillet: After cleaning, it's essential to re-season your cast iron skillet to restore its non-stick properties and protect it from rust. Coat the skillet with a thin layer of oil and heat it in the oven at a high temperature for about an hour. This process will help create a new non-stick surface.
Remember, it may take some effort and multiple attempts to remove the burned-on coating completely. Patience and persistence are key when cleaning cast iron cookware.
