Clean your ice maker every three to six months to prevent mold, mineral buildup, and off-tasting ice

A countertop ice maker works by freezing water in a cycle, and that water sits in pipes and trays where bacteria and mineral deposits can build up over time. Cleaning takes about 30 minutes and requires only items you likely have at home: white vinegar, warm water, and a soft cloth. The process is straightforward enough that you can do it yourself without calling a technician, though you will need to turn the machine off and let it sit between steps.

How often you clean depends on your water hardness and how often you use the machine. If you live in a hard-water area or use the ice maker daily, clean it every three months. If you use it occasionally or have soft water, every six months is usually enough. You will know it is time when the ice starts to taste odd, comes out slower than usual, or the machine takes longer to complete a cycle.

Key Takeaways

  • Turn off the ice maker and empty the bin before you start, then unplug it and let it sit for five minutes.
  • Fill the water reservoir with a 50-50 mix of white vinegar and warm water, run one cycle, then dump the ice and repeat the cycle twice more.
  • After the vinegar cycles, fill the reservoir with fresh water and run two full cycles to rinse out all vinegar taste.
  • Wipe down the exterior, the ice bin, and the water reservoir with a damp cloth, then let everything air dry before plugging back in.
  • If ice still tastes like vinegar after rinsing, run one more water-only cycle before using the ice.

What you need before you start

Gather white vinegar, warm tap water, a soft cloth or sponge, and a small bowl or cup. You do not need commercial ice maker cleaner—white vinegar works just as well and costs less. Avoid bleach or harsh chemicals, which can damage the plastic interior and leave residue that affects the taste of your ice.

Check your ice maker's manual to see if the manufacturer recommends a specific cleaning interval or warns against vinegar. Most countertop models are fine with vinegar, but a few older or specialty machines may have different instructions. If you cannot find the manual, the model number is usually on a sticker inside the ice bin or on the back of the unit.

Running the vinegar cleaning cycles

Turn off the ice maker and unplug it from the outlet. Empty the ice bin completely—any leftover ice will melt during the cleaning process and mix with the vinegar solution. Let the machine sit unplugged for five minutes so the internal components cool down slightly.

Plug the machine back in and fill the water reservoir with a 50-50 mix of white vinegar and warm water. If your reservoir holds 2 cups, use 1 cup vinegar and 1 cup water. Turn the machine on and let it run through one complete cycle. When the cycle finishes, the ice bin will contain vinegar-flavored ice—dump it out.

Repeat the vinegar cycle two more times without refilling the reservoir. Each time the cycle completes, empty the bin. After three vinegar cycles, the mineral deposits and buildup inside the pipes should be loosened and flushed out.

Rinsing out the vinegar taste

After the third vinegar cycle, empty the bin one final time. Now fill the reservoir with fresh, cool tap water—no vinegar. Run a complete cycle and dump the ice. Repeat this water-only cycle one more time. These two rinse cycles push out the remaining vinegar solution from the internal lines.

Taste a piece of the ice from the second rinse cycle. If it still smells or tastes like vinegar, run one more water-only cycle. This is normal if you have a larger machine or if the vinegar solution did not fully flush on the first two tries. Once the ice tastes neutral, you are ready to move on to the exterior cleaning.

Cleaning the bin, reservoir, and exterior

Remove the ice bin and wash it with warm soapy water and a soft cloth. Rinse it thoroughly and let it air dry. If the bin has stubborn stains or discoloration on the inside, soak it in a 50-50 vinegar and water solution for 15 minutes, then scrub gently and rinse.

Take out the water reservoir if it is removable—most countertop models have a pull-out tank. Rinse it under warm running water and wipe the inside with a damp cloth. If mineral deposits have built up on the walls of the reservoir, use a soft brush or the corner of a cloth to gently scrub them away. Do not use abrasive scrubbers, which can scratch the plastic.

Wipe down the exterior of the machine with a damp cloth to remove dust and any vinegar spray. Pay attention to the vents on the sides and back, where dust can accumulate and reduce cooling efficiency. Dry everything with a clean towel.

Reassembling and testing

Let the ice bin and reservoir air dry completely before putting them back in the machine. Moisture left inside can cause mold to grow faster. Once everything is dry, slide the reservoir back into place and set the bin underneath the dispenser.

Plug the machine back in and run one short test cycle to make sure water flows normally and the ice comes out at the usual speed. If the cycle takes much longer than it did before cleaning, there may still be mineral buildup—run another vinegar cycle and repeat the rinse steps. If everything looks normal, your ice maker is ready to use.

Preventing buildup between cleanings

Empty the ice bin at least once a week, even if you do not use all the ice. Old ice can develop off-flavors and odors, especially in humid climates. If you notice the ice smells stale, dump it and run a fresh cycle.

If you have very hard water, consider using filtered or distilled water in the reservoir instead of tap water. This slows mineral buildup and means you can go longer between deep cleanings. Some people keep a pitcher of filtered water next to the machine for this reason.

Wipe out the ice bin with a dry cloth once a month to prevent mold from growing on the walls. This takes 30 seconds and can extend the time between full cleanings.

Frequently Asked Questions

Can I use a commercial ice maker cleaner instead of vinegar?

Yes, commercial cleaners made for ice makers work, but white vinegar is cheaper and just as effective for routine cleaning. If you prefer a commercial product, follow the instructions on the bottle exactly—the mixing ratio and cycle count may differ from the vinegar method.

What if the ice maker stops making ice after I clean it?

This usually means water is not flowing into the reservoir or the machine did not fully drain after the vinegar cycles. Unplug the machine, empty the bin, and check that the water reservoir is seated properly. Plug it back in and run a water-only cycle. If ice still does not form, there may be a clog in the internal lines—contact the manufacturer for troubleshooting.

How do I know if my water is hard?

Hard water leaves white or chalky deposits on faucets, shower heads, and inside kettles. If you see buildup like this in your home, your water is hard and your ice maker will need cleaning every three months instead of six. You can also buy an inexpensive water hardness test strip at a hardware store.

Is it safe to drink ice made during the cleaning process?

No. Ice made during the vinegar cycles should be thrown away. Even after the rinse cycles, taste a piece first before using the ice in drinks. If it still tastes like vinegar, run one more water cycle.

Can I clean the ice maker while it is still plugged in?

No. Always unplug the machine before you open the reservoir or empty the bin. This prevents electric shock and keeps you safe while you are working with water inside the machine.
