Clean your Igloo ice maker every month to keep ice fresh and prevent mineral buildup

Igloo ice makers need regular cleaning to work properly and make ice that tastes good. Mineral deposits from water, mold, and bacteria can build up inside the machine over time, especially if you live in an area with hard water. A monthly cleaning takes about 30 minutes and requires only items you likely have at home—white vinegar, water, and a soft cloth.

The cleaning process is straightforward: you drain the water reservoir, run a vinegar solution through the system, rinse thoroughly, and wipe down the interior. Most Igloo models have a drain plug at the bottom front, making it straightforward to empty without taking the machine apart. You do not need special tools or replacement parts for routine maintenance.

Key Takeaways

  • Clean your Igloo ice maker once a month by draining the reservoir, running white vinegar through the system, and rinsing with fresh water.
  • Use a 1:1 ratio of white vinegar to water for the cleaning cycle, which dissolves mineral deposits and kills bacteria inside the lines.
  • The entire cleaning process takes 30 to 45 minutes and requires no special tools beyond a soft cloth and items from your kitchen.
  • If your ice tastes off or the machine makes less ice than usual, cleaning is often the first step before calling for repairs.

What you need before you start

Gather these items before you begin: white vinegar (plain, not apple cider or balsamic), a large bowl or bucket, a soft cloth or sponge, and access to fresh water. You will also need a small cup or container to catch water as it drains. Do not use bleach, rubbing alcohol, or commercial oven cleaners—these can damage the plastic interior and leave residue that affects ice taste.

Check your Igloo manual to locate the drain plug and water reservoir on your specific model. Most Igloo ice makers have the drain at the bottom front corner, but the exact location varies. If you cannot find your manual, the model number is usually printed on a sticker on the back or inside the door. You can search for it online to read a PDF version.

Step 1: Drain the water reservoir

Unplug the machine from the wall outlet first. This is the most important safety step and prevents the pump from running while you work. Wait a few minutes for any remaining water in the lines to settle.

Place your bucket or bowl under the drain plug at the bottom front of the machine. Turn the drain valve counterclockwise (or pull it outward, depending on your model) to open it. Water will flow out—this may take 5 to 10 minutes if the reservoir is full. Once the water stops flowing, close the drain plug by turning it clockwise or pushing it back in.

Step 2: Mix and run the vinegar cleaning cycle

Fill the water reservoir with a 1:1 mixture of white vinegar and fresh water. For a typical Igloo ice maker with a 2-liter reservoir, use 1 liter of vinegar and 1 liter of water. Pour this mixture into the reservoir through the top opening where you normally add water.

Plug the machine back in and press the power button. Select the ice-making cycle and let it run for about 5 minutes. This pushes the vinegar solution through the internal lines where mineral deposits collect. After 5 minutes, press the power button to stop the cycle. Do not wait for ice to form—you are cleaning the system, not making ice.

Let the vinegar solution sit inside the machine for 15 to 20 minutes. This gives the acid time to break down mineral buildup and kill bacteria. You will likely smell vinegar—this is normal and means the cleaning is working.

Step 3: Drain and rinse the system

Open the drain plug again and let all the vinegar solution flow out into your bucket. This step removes the loosened mineral deposits and vinegar residue. The water may look cloudy or slightly discolored—this is the buildup leaving the system.

Once the vinegar solution has drained completely, close the drain plug. Fill the reservoir with fresh water only (no vinegar this time) and run the ice-making cycle for another 5 minutes. Stop the cycle, let the water sit for a few minutes, then drain it again. Repeat this rinse cycle one more time to remove any remaining vinegar smell or taste.

Step 4: Wipe the interior and ice basket

While the machine is still unplugged and empty, use a soft, damp cloth to wipe down the interior walls and the ice basket. Pay attention to corners and crevices where mold or mineral deposits can hide. If you see any stubborn white or gray buildup, dampen your cloth with a small amount of white vinegar and rub gently until it comes off.

Wipe the ice basket thoroughly, especially the underside where water collects. Dry everything with a clean cloth before you reassemble the machine. Make sure no moisture remains in the basket or on the interior walls.

Step 5: Run fresh water through before making ice

Fill the reservoir with fresh water and plug the machine back in. Run one complete ice-making cycle without stopping it. This first batch of ice will have a slight vinegar taste even after rinsing—discard it rather than serving it. After you dump the first batch, run a second cycle. The ice from the second batch should taste normal.

Your Igloo ice maker is now clean and ready to use. Store it in a cool, dry place when not in use, and empty the reservoir if you will not be using the machine for more than a week. This prevents stagnant water from developing an odor.

Signs your ice maker needs cleaning sooner

If your ice tastes off, smells strange, or looks cloudy, clean the machine even if it has not been a month. These are signs that mineral buildup or bacteria has accumulated faster than usual, often because of hard water in your area. Cloudy ice specifically indicates mineral deposits in the water lines.

If the machine is making less ice than it used to, or if it takes much longer to complete a cycle, mineral buildup may be restricting water flow. Cleaning usually restores normal production. If cleaning does not improve performance, the pump or water line may need replacement, which requires contacting Igloo customer service.

Frequently Asked Questions

Can I use lemon juice or other vinegar instead of white vinegar?

White vinegar works best because it is inexpensive and has a consistent acidity level that dissolves mineral deposits without damaging plastic. Apple cider vinegar and lemon juice can work but may leave residue or odor. Avoid balsamic or flavored vinegars—they can stain the interior and affect ice taste.

What if the drain plug is stuck or leaking?

If the plug will not turn, explore a small amount of white vinegar around the threads and wait 10 minutes for it to soften mineral buildup, then try again gently. If it leaks after you close it, the seal may be worn. Contact Igloo customer service for a replacement drain plug—they are inexpensive and straightforward to swap out yourself.

How often should I clean if I have very hard water?

If your water is very hard (you notice white buildup on faucets or in kettles), clean your ice maker every two weeks instead of monthly. Hard water deposits accumulate faster and can reduce ice production noticeably. You may also want to fill the reservoir with distilled water instead of tap water to slow mineral buildup between cleanings.

Is it safe to use the ice maker right after cleaning?

Yes, as long as you run at least two complete cycles and discard the first batch of ice. The second batch should taste normal. If you still smell vinegar after the second cycle, run a third cycle before serving ice to guests.

What should I do if mold appears inside the ice basket?

Remove the basket and soak it in a 1:1 vinegar and water solution for 30 minutes, then scrub with a soft brush and rinse thoroughly. Mold usually means the basket was stored wet or the machine sat unused for a long time. After cleaning, make sure to dry the basket completely before putting it back in the machine.
