Rust on cast iron is fixable. Follow these steps to remove rust from cast iron, reseason the surface, and get your skillet back to nonstick cooking condition.

Quick Answer

Scrub the rust away with steel wool and a little oil or water, dry the pan completely, then apply a thin layer of cooking oil and bake it at 450°F to 500°F for about an hour. That single round of rust removal plus reseasoning restores most cast iron skillets. If the rust is deep or widespread, repeat the oil-and-bake cycle two or three times.

What You'll Need

Gather steel wool (fine or medium grade), a stiff-bristled brush, paper towels or clean rags, a mild dish soap, and a neutral cooking oil with a high smoke point, such as vegetable, canola, or flaxseed oil. You'll also need an oven, aluminum foil, and a baking sheet to catch drips. If the rust is light and surface-level, you may only need the steel wool and oil. For heavier rust, a wire brush or a brief soak in a 50/50 vinegar-water solution can help loosen the corrosion before scrubbing.

How to Remove Rust from Cast Iron

Start by scrubbing the rusty areas with steel wool. Apply firm, even pressure and work in small circles. If the rust is stubborn, dip the steel wool in a little oil or a diluted vinegar solution to help break it down. As you scrub, you'll see the rust turn into a dark, muddy residue. Wipe it away with a paper towel and keep scrubbing until you see bare iron or the original black seasoning underneath. Rinse the skillet with warm water and mild soap, then dry it immediately with a towel. Don't let it air-dry, as flash rust can form within minutes.

Reseasoning After Rust Removal

Preheat your oven to 450°F to 500°F. Place a sheet of aluminum foil on the bottom rack to catch any oil drips. While the oven heats, apply a very thin layer of oil to the entire skillet, inside and out, including the handle. Use a paper towel to wipe off any excess oil; the pan should look almost dry, not greasy. Place the skillet upside down on the middle rack and bake for one hour. Turn off the oven and let the skillet cool completely inside. This process polymerizes the oil into a hard, nonstick surface. For best results, repeat the oil-and-bake cycle two or three times, especially if the rust was extensive.

Preventing Rust Going Forward

After every use, wash the skillet with hot water and a stiff brush, using mild soap only if needed. Dry it thoroughly with a towel, then place it on a warm burner for a minute or two to evaporate any remaining moisture. While the pan is still warm, apply a thin coat of oil to the cooking surface. Store the skillet in a dry place, and if you stack other pans on top, place a paper towel or a pan protector between them to absorb moisture and prevent scratches. Avoid soaking cast iron in water or leaving it in a damp sink.

Step-by-Step Cast Iron Restoration

Scrub off the rust: Use steel wool or a wire brush to scrub rusty areas. Work in small circles with firm pressure. For stubborn rust, dip the steel wool in oil or a diluted vinegar solution. Checkpoint: The rust should turn into a dark residue that wipes away. Keep scrubbing until you see bare iron or black seasoning.
Rinse and dry immediately: Wash the skillet with warm water and mild soap, then dry it thoroughly with a towel. Do not let it air-dry. Common mistake: Letting the skillet air-dry allows flash rust to form within minutes. Dry it right away.
Apply a thin oil layer: Rub a high-smoke-point oil over the entire skillet, inside and out. Wipe off excess with a paper towel so the surface looks almost dry. Checkpoint: The pan should not look greasy. Too much oil leads to a sticky, uneven seasoning.
Bake to reseason: Place the skillet upside down on the middle rack of a 450°F to 500°F oven. Put foil on the bottom rack to catch drips. Bake for one hour, then turn off the oven and let the skillet cool inside. Common mistake: Skipping the foil or using too much oil can cause smoking and messy drips.
Repeat if needed: For heavy rust or a dull finish, repeat the oil-and-bake cycle two or three times until the surface is dark and smooth. Checkpoint: The skillet is ready when it has a uniform, slightly glossy black patina.
Maintain after every use: Wash with hot water and a stiff brush, dry thoroughly, warm on a burner, and apply a thin oil coat. Store in a dry place. Next step: Consistent maintenance prevents rust from returning.
