Be sure to grease the cast iron pans before use, put them in an oven at 180 ° C for about 60 minutes. Remove from the oven and wipe with a paper towel. This will enhance the effect of non-stick coating. The more often this is done, the longer the life of the cast iron cookware.
Cast iron dishes are not soaked with detergent. That would be disastrous for them. After each cooking, rinse with hot water and wash with a soft sponge and soap. Be sure to dry with a dry towel. In case of burnt stains, do not rub with a wire, but with a soft abrasive or detergent that will not damage the surface. If rust has appeared, a steel brush should be used to remove it, and then the procedure with lubrication and firing must be done. Do not leave water in the container for a long time, this can lead to its birth.
