Is Carbon steel baking pan dishwasher safe?
No — carbon steel baking pans are not dishwasher safe because the harsh alkaline detergent and high heat strip the seasoning and cause rust.

Why
Carbon steel is a reactive, uncoated ferrous metal that relies on a polymerized oil seasoning for non-stick properties and rust protection. In a dishwasher, the combination of high heat (up to 70°C/160°F), prolonged moisture, and alkaline detergents (pH 9-11) dissolves the seasoning layer, exposing bare steel. The specific failure is rusting: after one wash, the pan may develop orange spots; after repeated washes, the seasoning is completely stripped, leading to widespread rust and food sticking. The manufacturer (e.g., Lodge, Matfer Bourgeat) explicitly states to hand wash only. There are no parts to separate — the entire pan is one piece of steel.
How do you wash Carbon steel baking pan?
- Allow the pan to cool completely after use.
- Rinse with hot water and scrub with a non-abrasive brush or sponge to remove food residue.
- If needed, use a small amount of mild dish soap — avoid soaking or harsh detergents.
- Dry immediately and thoroughly with a lint-free cloth or paper towel.
- Apply a thin layer of cooking oil (e.g., vegetable or flaxseed) to the entire surface to maintain seasoning.
- Heat the pan on the stovetop or in the oven at 200°C/400°F for 10-15 minutes to set the oil.
- Store in a dry place; avoid stacking without a protective layer.
What happens if you put Carbon steel baking pan in the dishwasher?
If you put a carbon steel baking pan in the dishwasher, the first wash will likely remove some seasoning, leaving dull patches and light surface rust. After two or three washes, the seasoning will be completely gone, and the pan will develop orange-brown rust spots across the entire surface. The rust is not just cosmetic — it creates a rough, porous texture that causes food to stick and imparts a metallic taste. The pan becomes functionally unusable for baking unless you fully re-season it, which requires scrubbing off the rust and applying multiple layers of oil at high heat. Repeated dishwasher use can also cause pitting from prolonged moisture exposure, permanently damaging the steel.
Frequently asked questions
- Can I use soap on a carbon steel pan?
- Yes, a small amount of mild dish soap is fine for occasional use, but avoid soaking or harsh detergents as they can strip the seasoning.
- How do I remove rust from a carbon steel pan?
- Scrub the rust with steel wool or a scouring pad and warm water, then dry immediately and re-season the pan by applying a thin layer of oil and heating it.
- Can carbon steel pans go in the oven?
- Yes, carbon steel is oven-safe up to very high temperatures (typically 260°C/500°F or higher), making it ideal for baking and roasting.
- How often should I re-season my carbon steel pan?
- Re-season whenever food starts sticking or the surface looks dull or patchy. With proper care, every few months is typical.
