Causes Of Rust On Cast Iron
Moisture exposurecauses rust when water sits on the skillet. Wet cast iron left without drying will start to rust fast. Always dry the skillet right after washing.
Improper cleaningcan harm the skillet’s protective layer. Using soap or scrubbing too hard removes seasoning. This makes the surface raw and open to rust.
Lack of seasoningmeans the skillet loses its natural non-stick coating. Without this layer, iron is exposed to air and moisture. The skillet will rust without regular oiling and heating.

Cleaning Tips After Grilling
Never soak a cast iron skillet in water. Prolonged soaking causes rustto form quickly. Instead, clean it right after use with warm water and a brush or sponge.
Use gentle scrubbing tools. Avoid metal scrubbers that can damage the skillet’s seasoning. Soft brushes or non-abrasive sponges work best to remove food bits.
Dry the skillet immediately after washing. Use a clean towel to wipe off all moisture. You can also heat it on the stove for a few minutes to ensure it’s completely dry. This stops rust from forming.
Seasoning For Rust Protection
Choosing the right oilis key for protecting your skillet from rust. Oils with a high smoke point work best. These include flaxseed oil, grapeseed oil, and vegetable oil. They create a strong, lasting layer on the cast iron.
Applying thin layershelps the oil bond well with the skillet surface. Use a cloth or paper towel to spread a small amount evenly. Too much oil can make the surface sticky and uneven.
Baking processcures the oil into a hard, non-stick coating. Place the skillet upside down in an oven heated to 375-450°F (190-230°C). Bake for about one hour, then let it cool inside the oven. This process seals the skillet and stops rust.
