Clean the cookware with a soft sponge. Use only nylon scrub pads when needed to protect the enamel. Keep the cookware clean so that dust and debris do not create a surface abrasion for the food to stick to. Scratches from improper cleaning or utensils can have the same effect, so use nylon, plastic, wood or silicone utensils.
Heat the cookware for two to three minutes on medium heat, then add a thin layer of oil before adding food. The combination of the hot cookware and the oil protects it from sticking.
Avoid letting food sit in the cast iron after cooking, drain any oil or fat, and wash it right away. Food buildup and oil saturation in the enamel can damage the coating and cause sticking.
