Is Cast Iron Dishwasher Safe?
Standard seasoned cast iron should not go in the dishwasher because it can strip seasoning and cause rust. Enameled cast iron has a different caveat.
No for standard seasoned cast iron. A dishwasher can strip seasoning, leave the pan wet, and cause rust. Enameled cast iron is different: some pieces are technically dishwasher safe, but hand washing is often recommended to preserve the finish. If standard cast iron already went through the dishwasher, dry it, remove rust, oil it, and re-season.
