If you own or manage a restaurant, you likely have a commercial ice maker that provides a steady supply to use in beverages. However, since mold can reproduce inside the device, understanding how to prevent this buildup will promote sanitation and safety. Here's what to know about this fungal growth and the proper ice machine maintenance steps that will help avoid it.

What Causes Mold?

When your machine's lid or door is open, airborne fungal spores can blow into the interior. They can also enter if they contaminate the scooper or your staff members' hands, spreading throughout the device whenever someone retrieves ice.

An ice maker also uses a filter that eliminates impurities from intake fluids before the machine freezes them into ice. If mold and mildew build up in the mesh, they can circulate and contaminate ice.

Fungal spores reproduce in damp environments. Since some ice cubes melt inside the machine, the interior can become a breeding ground for mold and mildew. In addition to producing musty or rancid odors, these growths can cause health issues, like allergic reactions or asthma attacks, when inhaled or ingested. 

How Do You Prevent It?

Draining and cleaning the ice machine once every few months helps eliminate fungal spores, preventing mold and mildew development. First, unplug the appliance, and let the ice melt. The device typically has a built-in drain, so you should allow the moisture to exit on its own. However, if it doesn't have this part, use a wet-dry vacuum to siphon fluids out of the interior.

Next, prepare a cleaning solution. Diluting an EPA-approved antimicrobial disinfectant, such as chlorine or bleach, can effectively eliminate fungal spores. Take out any detachable parts, such as baskets and scoopers, before spraying the interior. Clean the removed components separately. 

Allow the solution to sit for about 10 minutes, then wipe all surfaces with a clean sponge or cloth. Wash away residual chemicals with soapy water. You should also clean the filter once weekly as part of your ice machine maintenance routine. This part resides in a compartment near the controls on the exterior. Rinse it with warm water, and allow it to dry before replacing it.
