How do you clean an ice maker and ice machine? While an ice maker’s bin can be removed and washed, an ice machine requires specific, but simple, cleaning steps. Learn how to clean an ice maker and ice machine for pure, high-quality ice every time: 1. Unplug the machine and turn off its water supply. 2. Empty the ice bin and wipe it down with warm water and mild dish detergent (some manufacturers may recommend a specific cleaning solution). 3. Remove the drain cap, allowing any residual water to drain into another container. Replace the drain cap. 4. Reposition the ice bin, plug the machine back in and run a complete cleaning cycle. 5. Dispose of the ice, refill the machine with clean water and run a second cycle. 6. Throw away the ice. After reconnecting the water supply, the ice machine is ready for use.
