Common Myths About Cast Iron

Myth: “Never wash cast iron with soap.”

Modern dish soap will not hurt properly seasoned cast iron. Seasoning is polymerized oil bonded to the iron, not a thin grease layer. Washing with a small amount of soap and warm water is perfectly fine. Just dry the pan thoroughly afterward.

Myth: “You can’t cook acidic foods in cast iron.”

Acidic foods like tomatoes can be cooked in cast iron, especially when the pan is well seasoned. Very long simmering can affect seasoning slightly, but normal cooking is not a problem.

Myth: “Rust means the pan is ruined.”

Rust on cast iron is almost always fixable. Surface rust can usually be removed with cleaning and reseasoning. Even heavily rusted pans can often be restored.

Myth: “Seasoning is just grease left on the pan.”

Seasoning is actually oil that has been polymerized by heat, creating a durable, protective cooking surface. It should feel smooth and dry, not sticky or greasy.

Myth: “You can’t use metal utensils.”

Metal spatulas and spoons are generally safe to use on cast iron. In fact, a flat metal spatula can help smooth the seasoning over time.

Myth: “You must never soak cast iron.”

Short soaking is usually fine if needed to loosen stuck food. Just avoid leaving it in water for long periods and always dry the pan thoroughly afterward.
