Cleaning old, baked-on grease from cast iron pots and pans requires some extra care to avoid damaging the seasoning (the protective layer) on the cast iron surface. Here's a step-by-step guide on how to do it effectively:
Materials you'll need:
- Dish soap (mild and preferably without harsh chemicals)
- Water
- Soft sponge or brush
- Plastic scraper or spatula
- Coarse salt
- Paper towels or cloth towels
- Vegetable oil or cast iron conditioner (for seasoning afterward)
Instructions:
Scrape off excess grease: Use a plastic scraper or spatula to gently remove any large pieces of baked-on grease from the surface of the cast iron. Avoid using metal utensils or anything abrasive, as it can damage the seasoning.
Add dish soap and water: Fill the cast iron pan with warm water and add a small amount of mild dish soap. Let it sit for a few minutes to loosen the grease.
Scrub gently: Use a soft sponge or brush to scrub the pan gently. Avoid using steel wool or harsh scouring pads, as they can strip away the seasoning. Focus on the areas with the most baked-on grease.
Salt scrub (if needed): If there are still stubborn grease spots, make a paste of coarse salt and water and use it to scrub the affected areas. The coarse salt acts as a gentle abrasive without harming the cast iron.
Rinse thoroughly: Rinse the pan thoroughly with warm water to remove all the soap and grease residues.
Dry completely: Use paper towels or cloth towels to dry the cast iron pan completely. Make sure it's completely dry to prevent any rusting.
Re-season the pan: After cleaning, it's essential to re-season the cast iron pan to restore its non-stick properties and protect it from rust. Preheat your oven to 375°F (190°C). Apply a thin layer of vegetable oil or a dedicated cast iron conditioner to the entire surface, including the handle. Wipe off any excess oil with a paper towel. Place the pan upside down on the oven rack and bake it for about an hour. Turn off the oven and let the pan cool inside.
Tips:
- Avoid using harsh chemicals or abrasive cleaning agents on cast iron, as they can damage the seasoning.
- Never soak cast iron in water for extended periods, as it can lead to rusting.
- If you have stubborn residue that doesn't come off with regular cleaning, you can try simmering water in the pan to help loosen it before scrubbing.
Regular maintenance and seasoning of your cast iron cookware will help prevent excessive buildup of grease and make cleaning easier in the future.
