Is Cast Iron Skillet dishwasher safe?
Not dishwasher safe✓ Verified
No — never put cast iron in the dishwasher; it strips the seasoning and causes rust.
Why
Dishwasher detergent and prolonged water exposure remove the polymerized oil layer ("seasoning") that gives cast iron its non-stick surface, and the standing moisture causes rust within hours.
How to wash it
Rinse with hot water while still warm, scrub with a stiff brush or chainmail scrubber, dry immediately on the stove, then rub a thin layer of neutral oil over the cooking surface to maintain the seasoning.
