Cast iron can last a lifetime — but only if you treat it right. Before your trip, make sure your pans and Dutch ovens are well-seasoned. That means they’ve got a baked-on layer of oil that prevents rust and helps with non-stick cooking. At camp, avoid using soap. Just scrub with a stiff brush and hot water, then dry completely and rub with a little oil before storing. If you’re cooking over a fire, be mindful of the heat — cast iron holds heat well, so you usually don’t need flames licking the sides. With a little care, your cast iron will keep getting better with every trip.
