Is it OK for your ultrasonic cleaner?

Silver (sterling 925)

Yes
Check first
No

Silver comes out free of dirt – but the tarnish does not go away.

Updated from your answers.

A few questions to be sure

Does the silver have deliberately darkened (oxidized) areas in the pattern?
Are there stones in the piece?

How to do it

Time
3 min
Water
Lukewarm, 30–40 °C

One drop of mild dish soap. Dry straight away and then polish with a silver cloth to deal with the tarnish.

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

Pandora states that ultrasonic cleaning is suitable for most metal jewelry without stones, with the exception of oxidized silver. Tarnish is a chemical sulphide film that water and ultrasound do not remove.

Watch out for

  • Does not remove tarnish – polish afterwards
  • Deliberately darkened patterns can lighten
  • Do not run silver together with other metals
