How to do it

Time
3 min
Water
Lukewarm, 30–40 °C

Short time. Shake out the water and let it dry with the hole facing down.

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

Hollow jewelry has thin walls and often small holes where water and dirt can get in and stay. There is no authoritative source, so we are cautious.

Watch out for

  • Dents or cracks: do not run it
  • Dark water that comes out later is trapped dirt
