How do you clean a portable ice maker?

If you have a model with the self cleaning cycle, use a capful of vinegar or lemon juice with water before running the self cleaning feature. If you have a model that does not offer the self cleaning cycle, it is best to run your first few cycles with a capful of vinegar or lemon juice and water. Then, make sure that you empty the water reservoir and run a few cycles with clean water to take care of any plastic taste from manufacturing. This process can also be used from time to time to help keep your ice maker clean from impurities and help with calcium buildup caused by hard water.
