How to Reseason a Carbon Steel Pan
Scrub back the damaged layer, wash, dry, then apply two or three thin rounds of oil heated past its smoke point. Full stripping is rarely necessary.
A carbon steel pan is only as good as its seasoning. Get the care right and the surface turns glassy, slick and genuinely non-stick; get it wrong and food sticks or rust creeps in. This section walks through every part of looking after your pan — how to season it from bare metal, which oils build the toughest patina, how to clean it after cooking (and whether soap is really off-limits), how to strip and re-season when things go sideways, and how to rescue a pan that has warped or spotted with rust. Follow these guides and a single pan will cook beautifully for decades.
