Cleaning your freezer ice maker is not a fun household task, but it’s an important one. Did you know that mineral deposits, mold, and general grime can accumulate in the ice maker? Over time, they can affect the quality of your ice and even cause appliance breakdowns. Don’t wait for these signs to escalate—just commit to a good cleaning routine.

Signs It’s Time to Clean Your Icemaker

If you’re not sure when your automatic ice maker needs cleaning, here are some common clues:

  • Cloudy or odd-tasting batches of ice
  • Visible residue (like discoloration, slime, or other residue inside the ice basket, ice trays, or icemaker compartment)
  • Slow ice production
  • Ice batch has an unusual smell
  • Clogged lines

Cleaning an Icemaker in Your Freezer

A regular cleaning routine prevents buildup and keeps your ice cubes tasting fresh. Aim to do it every 6 months. It doesn't take much effort if you follow this cleaning process:

  1. Turn off the ice maker: Locate the power-off button or lever and make sure the unit is completely turned off. This avoids damage to the machine while cleaning.
  2. Empty the ice machine: Remove any remaining ice from the bin. Discard old ice, because it may have absorbed impurities or odors over time.
  3. Wash the ice bin: Take out the ice bin and wash it with warm, soapy water. Rinse thoroughly with clean water to remove any soap residue, then dry it completely before replacing it.
  4. Clean any removable ice maker parts: Use a soft cloth or sponge and a mixture of warm water and a few drops of mild soap to gently wipe down parts of the ice maker itself. Pay close attention to any crevices or surfaces where mineral deposits may have formed.
  5. Check for ice mold or buildup: If you notice any stubborn residue, you can use a mixture of equal parts clean water and white vinegar. Apply it to the affected surfaces, let it sit for a few minutes, then scrub gently with a soft brush or clean cloth.
  6. Rinse and dry: Wipe down all components with a damp cloth to remove any soap or vinegar residue. Use a dry cloth to make sure everything is thoroughly dried.
  7. Turn the ice maker back on: Once all components are clean and dry, reassemble the ice bin, place it back in the freezer, and turn the ice maker back on.

Cleaning a Countertop or Portable Icemaker

Portable ice machines need love too—cleaning them keeps your ice at its best. Unlike a freezer ice maker, it's worth cleaning this appliance more often. Aim for every 1-2 months, or sooner, if you start to notice issues with the ice.

Despite being convenient and easy to use, they also require regular maintenance so you get clean, fresh ice cubes:

  1. Unplug the machine: Always start by unplugging the power supply to avoid any risk of electrical issues.
  2. Empty the water reservoir: Drain any excess water from the machine. If your model has a reservoir drain plug, open it to let the water out completely.
  3. Clean the water reservoir: Mix a solution of water and a little dish soap or white vinegar. Use a soft cloth or sponge to wipe down the reservoir, paying special attention to corners and crevices.
  4. Wipe down the exterior: Don’t forget to clean the outside of the machine and the ice scoop as well. A damp cloth with a bit of mild dish soap or vinegar will work well.
  5. Run a cleaning cycle: Some countertop models have a clean cycle function. If yours does, fill the reservoir with a water-vinegar solution (check your instruction manual for the right ratio) and run a cleaning cycle. Drain the solution afterward and rinse the machine by running another cycle with fresh water.
  6. Dry thoroughly: Before using the machine again, make sure all components are completely dry to prevent ice mold or mildew.

Can I use bleach to clean my icemaker?

While a mild bleach solution can be used to sanitize, it’s not typically necessary for routine cleaning. White vinegar is a safer, more natural option that effectively removes buildup and odors without leaving behind harmful chemicals. If you choose to use bleach, make sure to dilute it properly and rinse thoroughly to avoid contaminating your ice.
