Remove the crank and beater from the bucket. Use a screwdriver to remove screws from the side of the bucket, if necessary. Disassemble the crank and beater for easier cleaning.
Add liquid dish soap to hot water and wash each piece of the crank and beater separately in the sink with a sponge. Remove remaining food particles by soaking the crank and beater in 1 cup of white vinegar and 1 gallon of hot water to dissolve and disinfect. Use a nylon scrub pad to remove particles from hard-to-reach areas on the crank and beater. Rinse pieces thoroughly in cool water.
Wash the bucket completely with hot, soapy water and rinse well. Let the bucket air dry overnight.
