Is it OK for your ultrasonic cleaner?

Antique jewelry and heirlooms

Yes
Check first
No

Often worn settings and unknown treatments – let a jeweler look first.

Updated from your answers.

A few questions to be sure

Are there stones in the piece?
Does any stone move or rattle when you tap the piece lightly?
Are the stones glued (no metal holding them)?

How to do it

Time
3 min
Water
Lukewarm, 30–40 °C

Only after a check. Short time, and count the stones afterwards.

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

Older jewelry can have worn prongs, foil-backed stones, enamel or glued parts. Treatments are rarely documented. Solid metal without stones is often fine.

Watch out for

  • Foil-backed stones: avoid
  • Check the prongs
