Use the descaling solution and cleaning cycle specified in your ice maker’s manual. There is no single mixture that is safe for every machine: some countertop models allow vinegar or a branded cleaner, while other units require a different product. Using the wrong chemical can damage parts or leave residue in the water path.

Before you start
- Find the model number and read the cleaning section of the manual.
- Check whether the manufacturer calls for descaling, sanitizing, or both. They are separate jobs and may use different products.
- Buy only a cleaner approved for that model. If you use an ice-maker cleaning kit, confirm that the product matches your unit before ordering.
- Remove the ice and disconnect power when the manual instructs you to.
General descaling sequence
- Empty the bin, drain the unit, and remove filters or screens only as directed.
- Mix the approved descaler at the exact concentration on the bottle or manual. Never combine descaler with bleach, sanitizer, or another cleaner.
- Add the solution to the reservoir or water path as directed, then run the machine’s clean/descale cycle. Do not run a normal ice-making cycle with cleaner unless the manual explicitly says to.
- Drain the solution fully. Refill with clean water and run the rinse cycle the manufacturer specifies.
- Wash and dry the removable bin using the manual’s instructions, then reinstall filters and other parts.
- Discard the first batch or batches of ice after cleaning, as your manual directs. Resume serving ice only when the system has been rinsed and the ice has no cleaner taste or odor.
Model-specific example
GE’s instructions for its Opal nugget-ice maker describe model-specific vinegar or Opal Cleaning Kit steps for descaling and a separate bleach solution for sanitizing. Those directions do not apply automatically to other brands or Opal models. Use the GE Appliances Opal cleaning instructions only if you own the model they cover.
For routine cleaning of a different machine, see our guide to cleaning an ice maker; for the Opal 2.0, use the model-specific descaling guide.
When cleaning does not solve the problem
If ice production remains slow, water leaks, or the unit makes unusual noises, stop the cycle and check the troubleshooting section of the manual. A clogged water filter, low water supply, or failed component can look like scale buildup. Contact the manufacturer if the machine still shows an error or cannot drain and rinse properly.
