Cleaning burnt-on grease from a cast iron skillet requires some gentle techniques to avoid damaging the skillet's seasoning and surface. Here's a step-by-step guide to effectively clean it without causing harm:
Safety first: Allow the skillet to cool down completely before attempting to clean it. Cleaning a hot cast iron skillet can be dangerous and may cause burns.
Scrape off loose debris: Use a plastic or wooden spatula to gently scrape off any loose burnt bits from the skillet's surface. Avoid using metal utensils or abrasive materials, as they can scratch the seasoning.
Soak in hot water: Fill the skillet with hot water and let it sit for a while. This will help to loosen the burnt-on grease and make it easier to remove.
Use gentle scrubbing: After soaking, use a soft sponge or a non-abrasive scrubber to gently scrub the surface. You can also use a brush designed specifically for cast iron cookware. Avoid steel wool or harsh scouring pads, as they can strip away the seasoning.
Add mild dish soap (optional): If the burnt-on grease is particularly stubborn, you can add a small amount of mild dish soap to the water. However, make sure to rinse the skillet thoroughly afterward to remove any soap residue.
Boil water in the skillet (optional): If there are still stubborn burnt spots, you can fill the skillet with water and bring it to a gentle boil on the stove. The boiling water should help to further loosen the grease.
Salt scrub (if needed): For tougher stains, you can create a paste using kosher salt and a small amount of water. Apply the paste to the affected areas and gently scrub with a soft brush or sponge.
Rinse thoroughly: After cleaning, make sure to rinse the skillet thoroughly to remove any remaining debris or cleaning agents.
Dry completely: Once cleaned, dry the skillet completely using a clean towel. To prevent rusting, you can place the skillet on a low flame for a minute or two to ensure it's completely dry.
Re-season the skillet (if necessary): If the cleaning process has removed some of the seasoning, it's a good idea to re-season the skillet. Apply a thin layer of oil to the surface and heat it in the oven at a high temperature for an hour.
Remember, regular maintenance and proper seasoning are key to keeping your cast iron skillet in excellent condition. After each use, it's essential to clean and dry it thoroughly, applying a light coat of oil before storing it to maintain its non-stick properties and prevent rust.
