Cleaning A Cast Iron Skillet

I have found the easiest way to clean my cast iron skillet is with Kosher Salt!  

Once the pan is cool, I sprinkle a generous amount of salt in the pan.  Then with wet paper towel, I scrub the skillet with the salt.  Within minutes, the dried crusty remains in the pan are gone.  I rinse well, then dry the pan over medium heat on the stove, to prevent rust.  Works perfectly!
