Clean your Opal ice maker monthly with water, vinegar, and a soft brush to keep it running well and prevent mineral buildup

Opal ice makers need regular cleaning to work properly and last longer. Mineral deposits from water, dust, and ice residue build up inside the machine and slow down ice production or cause it to stop working altogether. The good news is that cleaning takes about 30 minutes and requires only items you likely have at home: white vinegar, warm water, a soft brush, and a cloth.

The process has two parts: a vinegar soak to dissolve mineral deposits, and a water rinse to flush everything out. You do not need special cleaning solutions or tools. Opal recommends cleaning monthly if you use the machine daily, or every three months if you use it less often.

Key Takeaways

  • Unplug the machine and empty the ice bin and water reservoir before you start cleaning.
  • Mix equal parts white vinegar and warm water, pour it into the reservoir, and let it sit for 15 to 20 minutes to break down mineral buildup.
  • Use a soft brush to gently scrub the water inlet, ice chute, and any visible deposits inside the bin.
  • Run two full cycles of fresh water through the machine to rinse out all vinegar and residue before making ice again.

What you need before you start

Gather these items in one place so you do not have to stop midway through. You need white vinegar (the standard 5 percent acidity kind from any grocery store), warm water from your tap, a soft-bristled brush or old toothbrush, a clean cloth or paper towels, and a small bowl or cup. Do not use bleach, harsh chemicals, or abrasive scrubbers — they can damage the plastic and metal parts inside the machine.

Check your Opal manual for any specific warnings about your model. Most Opal machines are similar, but some older models may have slightly different water access points. If you no longer have the manual, you can find it on the Opal website by entering your model number.

Step 1: Empty and unplug the machine

Turn off the ice maker and unplug it from the wall outlet. This is a safety step and also prevents the machine from trying to make ice while you are cleaning inside. Open the ice bin and remove any ice that is in there — you can throw it away or save it if you want.

Next, locate the water reservoir. On most Opal models, it is a removable tank at the back or side of the machine. Pull it out gently and empty any water that is inside. Set it aside on a clean surface. If your model has a built-in reservoir that does not come out, you will skip this step and pour the vinegar solution directly into the water inlet opening instead.

Step 2: Mix and pour the vinegar solution

Pour equal parts white vinegar and warm water into a bowl or measuring cup. A 50-50 mix is the standard ratio — for example, one cup of vinegar and one cup of water. Stir it together so it is mixed evenly.

If your machine has a removable reservoir, pour the vinegar solution into it and reinstall it in the machine. If your machine has a fixed reservoir, pour the solution slowly into the water inlet opening at the top or back of the machine until the reservoir is full. Work slowly so the liquid does not splash or overflow. Do not plug the machine back in yet.

Step 3: Let the vinegar soak

Leave the vinegar solution sitting inside the machine for 15 to 20 minutes. This soak time allows the acid in the vinegar to dissolve mineral deposits like calcium and lime that have built up on the water lines and inside the ice-making chamber. You do not need to do anything during this time — just let it sit.

If you can see mineral buildup on the outside of the water inlet or around the ice chute opening, dip your soft brush into the vinegar solution and gently scrub those spots while you wait. Do not scrub hard or use a rough brush, as you can scratch the plastic.

Step 4: Scrub the accessible parts

After 15 to 20 minutes, unplug the machine if it is plugged in, and open the ice bin. Use your soft brush to gently scrub the inside walls of the bin, the ice chute, and any other parts you can reach. Pay special attention to corners and crevices where mineral deposits tend to collect. Dip the brush in the remaining vinegar solution as needed to keep it wet.

If you can access the water inlet or any removable parts, clean those too. For the water inlet, use a small brush or the corner of a cloth to wipe away any visible buildup. Do not force anything or use tools that could damage the plastic or metal.

Step 5: Drain and rinse with fresh water

Once you have finished scrubbing, drain the vinegar solution from the machine. If your machine has a drain plug at the bottom, open it and let the liquid flow into a sink or bucket. If there is no drain plug, you will need to tilt the machine carefully or use a turkey baster or syringe to remove the liquid from the reservoir opening. Work slowly to avoid spilling.

After the vinegar is drained, refill the reservoir with fresh tap water. Plug the machine back in and run a full ice-making cycle. Once the cycle is complete, empty the ice bin and discard that ice — it may taste or smell like vinegar. Refill the reservoir with fresh water again and run a second full cycle. This second rinse removes any remaining vinegar taste or smell. Empty the ice from the second cycle as well.

How often to clean and what to do between cleanings

If you use your Opal machine every day, clean it once a month. If you use it a few times a week, clean it every two to three months. If you use it rarely, cleaning every three to four months is usually enough. The more you use the machine, the faster mineral deposits build up, especially if you live in an area with hard water.

Between cleanings, keep the water reservoir filled with fresh water and change it every few days if you are not using the machine. Stagnant water can grow bacteria and cause odors. If you notice that ice production has slowed down, the ice tastes odd, or the machine is making unusual noises, clean it right away rather than waiting for your scheduled cleaning date.

Frequently Asked Questions

Can I use a different type of vinegar or cleaning product?

White vinegar is the safest choice because it is food-safe and the acidity level is consistent. Apple cider vinegar can work but may leave a smell. Do not use bleach, commercial descaling products, or harsh chemicals — they can damage the machine or leave residue that gets into your ice. Stick with white vinegar and water.

What if the vinegar smell does not go away after two rinses?

Run a third cycle with fresh water and discard that ice as well. If the smell persists, let the machine sit unplugged overnight with the ice bin open to air out. You can also try running a cycle with a small amount of fresh lemon juice mixed into the water, which can help neutralize vinegar odor.

Is it safe to clean the machine while it is plugged in?

No. Always unplug the machine before you open it, pour vinegar inside, or scrub any internal parts. This prevents electrical shock and also stops the machine from accidentally turning on while your hands are inside.

What should I do if water leaks out during cleaning?

Place towels or a shallow pan under the machine before you start draining. If the machine leaks during normal use after cleaning, make sure the water reservoir is seated properly and the drain plug is fully closed. If leaking continues, contact Opal support — it may indicate a cracked reservoir or loose connection.

Do I need to clean the ice bin separately?

The ice bin gets cleaned during the vinegar soak and rinse cycles, but you can also wash it separately in warm soapy water if it looks dirty or smells stale. Dry it completely before putting it back in the machine to prevent mold growth.
