The chlorine enters the machine from the municipal water supply. It can be removed from the water supply by using a charcoal or activated carbon water filter to treat the water to the ice machine. If staining is severe, filters of this type are recommended. Exterior Cabinet Cleaning: The exterior cabinet may be cleaned by scrubbing with soap and water.
