Things That Shouldn't go into the Dishwasher - part 4

Cast Iron Cookware

Cast iron skillets and pans have been around for centuries and they can last nearly forever if they are cared for properly. To keep cast iron from rusting and food from sticking, it must be seasoned with oil. The oil penetrates the iron and leaves a near perfect cooking surface.

When the cast iron is placed in the dishwasher, the harsh detergent and excessive water strips away the oil and leaves the cast iron unusable. The seasoning process must be completely started over. 

Comment:  I knew this one.  I always wipe my cast iron pans out with a paper towel removing anything that might be left after making my bread and then lightly wipe it with oil.
