Is it OK for your ultrasonic cleaner?

Metal frames

Yes
Check first
No

Metal frames come out clean in the hinges and nose pads – the lenses decide.

Updated from your answers.

A few questions to be sure

Do the lenses have an anti-reflective or other coating?
Do the lenses have scratches or patches where the coating has come off?

How to do it

Time
3 min
Water
Lukewarm, 35 °C at most – never hot

Lukewarm water and one drop of mild dish soap. Dry the hinges thoroughly.

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

Zeiss names ultrasonic cleaning as the best way to clean frames. Dirt collects in hinges, screws and nose pads. If the lenses are still in, the advice for the lenses applies.

Watch out for

  • Lenses still in: see coating
  • Loose screws can loosen further – check afterwards
