Why
De Buyer carbon steel pans are made of raw carbon steel, which is highly reactive to moisture and alkaline dishwasher detergents. The high heat and prolonged moisture in a dishwasher will strip the seasoning (polymerized oil layer) and cause immediate rusting. The alkaline detergent accelerates oxidation, leading to pitting and corrosion. De Buyer's official care instructions state that these pans must be hand washed and dried immediately. After one wash, the pan will show patchy rust and loss of nonstick properties; repeated washes cause deep pitting and irreversible damage. The pan's seasoning is a functional coating that must be maintained; dishwasher use destroys it, making the pan unusable until re-seasoned.
How do you wash De Buyer carbon steel pan?
- Wash the pan by hand with hot water and a soft sponge or brush; avoid abrasive pads.
- Use a small amount of mild dish soap only if needed; for routine cleaning, use only water.
- Rinse thoroughly with hot water.
- Dry the pan immediately with a clean towel or heat it on the stove to evaporate all moisture.
- Apply a very thin layer of cooking oil (e.g., vegetable or canola) to the entire surface to prevent rust.
- Store in a dry place; avoid stacking other pans directly on top.
What happens if you put De Buyer carbon steel pan in the dishwasher?
If you put a De Buyer carbon steel pan in the dishwasher, after one cycle you will notice the seasoning has been stripped in patches, revealing bare gray metal that quickly begins to rust. The pan will have a reddish-brown discoloration and a rough, tacky feel. After repeated washes, the rust becomes pervasive, forming deep pits and flaking. The pan will no longer be nonstick and may impart metallic flavors to food. The damage is both cosmetic and functional: the pan can be re-seasoned if caught early, but severe pitting may require sanding or replacement. The manufacturer warns that dishwasher use voids any warranty and is not recommended.
Frequently asked questions
- Can I use soap on my De Buyer carbon steel pan?
- Yes, you can use a small amount of mild dish soap occasionally, but it's best to avoid soap to preserve the seasoning. If you use soap, rinse thoroughly and dry immediately.
- How do I remove rust from my carbon steel pan?
- Use a stainless steel scrubber or fine-grit sandpaper to remove rust, then wash, dry, and re-season the pan immediately.
- What oil should I use for seasoning?
- Use oils with a high smoke point like grapeseed, flaxseed, or canola oil. Apply a thin layer and heat until smoking.
- Can I cook acidic foods in my carbon steel pan?
- Avoid cooking highly acidic foods (tomatoes, vinegar) for long periods, as they can strip the seasoning. Brief contact is usually fine.
