Cleaning a commercial ice maker is commonly overlooked by many owners of commercial ice machines, and how to properly clean a commercial ice maker is even more of an in-depth process than most people realize. Taking the time to properly clean a commercial ice maker can take hours, and when done incorrectly, it can cause many problems and potentially cost a lot of money to repair. When a commercial ice maker is properly cleaned and maintained a commercial ice machine can easily last 15 years or longer. A commercial ice machine that is not properly cleaned and maintained may only last 4-7 years, depending on water quality.
