How to Remove Surface Rust From a Cast-Iron Skillet

Light surface rust on cast iron can often be scrubbed away, followed by thorough drying and restoration of its protective seasoning.

Steps to follow

1. Inspect the pan for shallow orange rust rather than deep structural damage.
2. Scrub affected areas with a suitable brush or pad and a little water.
3. Rinse off loosened rust and residue.
4. Dry immediately with a towel and low heat on the stove.
5. Apply a very thin layer of cooking oil and follow a reliable heat-seasoning procedure.

Why it works

Bare iron reacts readily with moisture and oxygen. Seasoning is a thin polymerized oil film that reduces exposure to moisture, so restoration must include drying and surface protection after rust removal.

Mistakes to avoid

Avoid leaving a stripped, freshly cleaned pan wet. Deep pitting, cracks or flaking that resembles damaged enamel need a different assessment.

Frequently asked question

Is a rusty skillet automatically ruined?

No. Mild surface rust is often reversible, but cracked cookware should not be used.
