Never – Apple explicitly names ultrasonic cleaning as harmful.
With these answers we do not recommend the ultrasonic cleaner, so there is no how-to.
Pick your cleaner to see if it fits, which setting to use and what its manual says.
Why
Apple lists ultrasonic cleaning among the methods that can damage Apple Watch. Smartwatches have a battery, sensors and speaker openings that are not made for vibration under water.
Do this instead
- Wipe with a lint-free, slightly damp cloth
- Detached silicone straps can be run separately
