It’s hard to remember to clean the refrigerator regularly, let alone an undercounter ice maker. But actually, your ice maker needs to be cleaned just as often (if not more) than your refrigerator for it to function optimally and produce clean, high-quality ice. We’ll review how to clean an ice maker with a step-by-step guide to using its clean and sanitize features.

How to Clean an Ice Maker: A Step-By-Step Guide

A dirty ice maker can not only lessen the life of your machine but could allow harmful mold and bacteria to contaminate ice. Fortunately, learning how to clean an ice maker can be straightforward with the self-cleaning and sanitizing functions.

Ice Machine Cleaning: How Do I Clean the Inside of My Ice Maker?

Cleaning an ice maker or ice machine is important for a number of reasons. Ice machine cleaning helps prevent the buildup of bacteria and other harmful contaminants that can affect the quality and safety of the ice produced. 

If an ice maker or machine is not cleaned regularly, it can become a breeding ground for bacteria and other microorganisms, which can then be transmitted to the ice and consumed by people. 

In addition to the potential health risks, a dirty ice maker or ice machine can also produce ice that tastes or smells bad, which can be off-putting to customers or guests. Regular cleaning also helps extend an ice maker’s lifespan by removing dirt, grime, and other substances that can wear down the appliance over time.

By regularly cleaning your ice maker or ice machine, you can help ensure that the ice produced is safe, high quality, and free of any unpleasant odors or tastes.

Is Your Ice Contaminated with Bacteria & Mold?

The answer may surprise and disturb you. Your home is your sparkling clean sanctuary, but the unpleasant truth is that mold, bacteria (Salmonella, Listeria, E. coli, Shigella), deadly viruses, feces, and mineral build-up could be growing in your ice machine. Disgusting, right?
When not cleaned thoroughly dirty ice (even from a high-end maker like Scotsman, U-line, or Sub-Zero*) can make you sick. Even those of us who do occasionally wipe down or clean our ice maker, aren’t taking one thing into consideration: Biofilm.

What Is Biofilm?

Biofilm or “slime” buildup from ongoing microbial growth can and does occur in commercial and in-home ice-makers. Biofilm is a collection of microorganisms, mainly bacteria, that grow together to form a shielding effect on the bacteria held within them, preventing the normal cleaning process from doing its job to eradicate these bacteria and viruses. For instance, Listeria, a disease-causing bacteria, can be 1Kx times harder to eliminate under a biofilm.

In one recent fast-food chain restaurant study, ice was found to contain feces. And in another jaw-dropping study, ice machines from several national fast-food chains were found to contain more bacteria than what’s typically found in a toilet. Like your scotch on the rocks? The truth is, even drowning your ice in hard alcohol isn’t enough to kill some deadly bacteria or viruses, according to a study done at the University of Texas where Salmonella, E. coli, and Shigella all survived being submerged in scotch and 85 proof tequila. Plus, viruses such as the Norwalk virus actually thrive in frozen crystalline structures!

To clean an ice maker and ice machine, you will need the following items:

  • A soft cloth or sponge
  • A vinegar solution specifically designed for cleaning appliances
  • A small brush (optional)
  • A bucket

Follow these steps for how to clean an ice maker:

  1. Unplug the ice maker or turn off the power to the ice machine.
  2. Remove any ice that is in the ice bin and discard it.
  3. Wipe down the exterior of the ice maker or ice machine with a soft cloth or sponge and a vinegar solution.
  4. Use a small brush to gently scrub away any stubborn stains or dirt.
  5. Wipe down the interior of the ice bin.
  6. If your ice maker or ice machine has a removable ice tray or ice mold, remove it and wash it with a vinegar solution. Rinse it thoroughly and dry it before returning it to the ice maker or ice machine.
  7. Fill a bucket with a vinegar solution and use it to scrub the inside of the ice maker or ice machine.
  8. Rinse the interior thoroughly with clean water.
  9. Wipe down the interior and exterior of the ice maker or ice machine again with a clean, dry cloth to remove any remaining cleaning solution.
  10. Plug the ice maker or turn the power back on to the ice machine.
  11. Allow the ice maker or ice machine to run for a few minutes to ensure that it is fully drained and to flush out any remaining cleaning solution.
  12. Discard any ice that is produced during this process, then refill the ice bin and resume normal use.

How Often Should an Ice Maker Be Cleaned?

If you’re wondering how to clean an ice maker, you’ll want to know how often it needs to be cleaned. We recommend cleaning an ice maker at least once every three to six months, depending on the specific model and how frequently it is used. However, some ice makers may need to be cleaned more frequently if used heavily or located in a particularly dirty or dusty environment. 

If you notice any changes in the quality or taste of the ice being produced, it may be a good idea to clean the ice maker more often. Also, make sure to clean an ice maker before storing it for an extended period of time or after it has been in storage. Additionally, if you notice any visible dirt or grime buildup on the exterior or interior of the ice maker, it is a good idea to clean it as soon as possible to prevent any potential problems or poor ice production.
