Although, some may say they can be put in the dishwasher. I don't recommend putting enameled cast iron in the dishwasher as it can be tough on the finish. Typically warm, soapy water is all that's needed to clean! If there are some stubborn bits, you can add water and a little baking soda then pop back on the stove to simmer and use a wooden spoon to scrape off the bits. If it REALLY needs a good cleaning, Bar Keeper's Friend works very well.
