After a hearty meal, it's important to clean the cast iron Dutch oven properly to ensure its longevity. Avoid using soap as it will strip the seasoning from the cast iron Dutch oven. Instead, use hot water and a stiff brush to scrub away Dutch oven food particles. After cleaning the Cast Iron Camp Oven, be sure to dry the Dutch oven thoroughly to prevent rust. Applying a light coat of oil after cleaning the Cast Iron Camp Oven will help maintain seasoning and prevent rust.
