Enamelware can be easily cleaned. Once cookware has cooled, fill with warm soapy water and wash by hand with a soft sponge or brush. If you find burn marks or tough residue, simply soak in warm soapy water for a short period of time up to an hour before washing. Tougher stains can be removed by coating areas with bicarbonate of soda or lemon juice for a half an hour, and then washing as normal. Although most enamel is dishwasher safe, the surface may dull slightly and chip, and any exposed metal may rust. Small chips and defects in enamel are likely to occur over time, but this doesn’t prevent it from being useable as long as the interior of cookware is not damaged or rusting.
