How to get rust off cast iron

Have you ever pulled out your beloved cast iron skillet, only to discover it’s been tarnished by rust? Perhaps it hasn’t seen the light of day in your kitchen for a while, or maybe it’s been stored improperly, left vulnerable to moisture. The sight of that rust can be disheartening, especially when you know how versatile and long-lasting cast iron cookware can be when properly cared for. If you’re wondering how to reclaim your favorite pan from the grips of rust, you’re not alone, and today we’ll be tackling this common kitchen dilemma.

To remove rust from cast iron, scrub the affected area with a mixture of equal parts vinegar and water using a steel wool pad or a stiff brush, then rinse, dry thoroughly, and re-season the skillet with oil.

Restoring rusted cast iron involves a few straightforward steps. Start by creating a cleaning solution made from equal parts white vinegar and water. This acidic mixture helps break down the rust. Soak the rusty area or the entire piece in this solution for about 10 to 15 minutes. If the rust is more heavily set, you may let it soak longer, but be cautious as prolonged exposure can damage the seasoning.

Once soaked, take a piece of steel wool or a stiff scrub brush and begin scrubbing the rusted spots. Be prepared to use some elbow grease, as you may need to apply firm pressure to effectively remove all the rust. After the rust is removed, rinse the cast iron thoroughly with water to wash away any remaining debris. It’s crucial to dry the skillet immediately with a clean cloth or paper towel to prevent further rusting.

Finally, it’s essential to re-season your cast iron cookware to restore its protective layer. Apply a thin coating of vegetable oil or any cooking oil of your choice over the entire surface, and then bake the skillet upside down in an oven at 375°F (190°C) for about an hour. This method will help to create a durable, non-stick surface that guards against future rust. Regular maintenance, such as storing it in a dry place and avoiding soaking it in water, will keep your cast iron in tip-top condition for years to come.
