Once a year -- flexable putty knife to run around the inside diameter, scotch brite the rest. The inside of the lid, I place it upside down in a cardboard box and spray with oven cleaner. After several applications and elbow grease --- down to porcalin. Freashly cleaned and ready to go.
Every contest -- all racks wire brushed and wiped, outside window cleaner, alway's look new when taken care of.
Covered and ready for the next contest -----
anal and know it
