How should you clean the bottom of an iron?

Enamel coated cast iron can usually be washed like other cookware - with dish soap, or in the dishwasher. Because the enamel is prone to chipping, no hard surfaces (like a dishwasher prong) should be allowed to contact the enamel during the washing process. Some coated cast iron pots have spots of bare iron on their rims or wooden handles - these should be washed by hand and dried immediately. Many manufacturers recommend Bon Ami or Bar Keeper's Friend for handwashing enameled cast iron (however this kind of powdered cleanser should never be used on bare/seasoned cast iron).
