Ordinary Lego bricks withstand lukewarm water – not electronics or stickers.
A few questions to be sure
How to do it
- Time
- 3 min
- Water
- Lukewarm, 30–40 °C
40 °C at most. Run a few pieces at a time and let them air-dry.
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
LEGO says bricks can be washed by hand at 40 °C at most, but not in a dishwasher. Electric parts and stickers do not withstand water.
Watch out for
- Battery boxes and motors: avoid
- Stickers can come off
