How to Delete Rust From a Skillet

Cast-iron skillets become worn and rusted after regular use.

Cast iron skillets that have rusted because of age or improper seasoning can be restored with relative ease. However, skillets with Teflon or nonstick coatings that have rusted should be thrown away or sent back to the manufacturer for re-coating, since the damaged coating may be a health concern even if you remove the rust on the inside of the skillet. When cleaning a cast-iron skillet, never use a metallic or overly abrasive sponge to remove rust or cooked-on food.

Things You'll Need

• Teakettle or medium saucepan with a tight-fitting top
• Non-metallic sponge
• Mild dish soap
• Paper towels or kitchen towel
• Unsalted vegetable shortening, for seasoning
• Baking sheet
• Aluminum foil

Instructions

Removing Rust

1. Fill a teakettle or medium saucepan with cold water from the tap and bring it to a boil over high heat on top of the stove.

2. Place the cast-iron skillet in the sink and pour the boiling water into the skillet. Cover the skillet and allow it to rest until the water is cool, approximately 60 to 90 minutes.

3. Pour the water out of the skillet and wash the inside with a non-metallic sponge and mild dish soap. Dry the skillet inside and out with paper towels or a kitchen towel.

Seasoning the Skillet

1. Preheat the oven to 350 degrees Fahrenheit.

2. Rub the inside and outside of the skillet with unsalted vegetable shortening. Place the cast-iron skillet upside down on a baking sheet lined with aluminum foil.

3. Put the cast iron skillet in the oven on the center rack for 90 minutes. Remove the skillet and allow it to rest at room temperature until it is cool enough to touch.

4. Rinse the skillet with warm water from the tap. Pat it dry with clean paper towels or a kitchen towel, and store it as desired.

Tips & Warnings

• If the rust is not completely removed after allowing the water to cool, repeat the process once more before seasoning the cast-iron skillet in the oven.
