Can you put cast iron in the dishwasher?
Do not put cast iron in the dishwasher. It can strip seasoning and cause rust.
Updated June 10, 2026
Why
Dishwasher detergent removes seasoning while water and heat encourage rust.
Caveats
- Wash with hot water and a small amount of mild soap if needed.
- Dry on the stove or with a towel right away.
- Re-oil after cleaning.

What if a cast iron skillet already went through the dishwasher?
Rescue it promptly: rinse, scrub off any rust spots with hot water and a brush, dry it completely on the stove or with a towel, then rub on a thin coat of cooking oil. One cycle usually strips some seasoning but rarely ruins the pan; re-season with a few oiled heat cycles if food starts sticking.
Is enameled cast iron dishwasher safe?
Enameled cast iron is a different case from bare cast iron: many makers allow the dishwasher, but hand washing keeps the enamel glossy and the rims (which are often bare metal) rust-free. Check the care instructions for your exact pan.
