Our cast iron cookware cleaner will do the job without damaging the enamel. Black enamel interior: use of the cleaner is not recommended for products with a black enamelled surface as this interior builds a natural non-stick layer or patina with easy release properties over time. For that type of interior all food debris left behind after cooking should be removed by washing and in warm soapy water. Stuck on food can be removed by soaking and a washing up brush.
