Is it OK for your ultrasonic cleaner?

Scratched or damaged lenses

Yes
Check first
No

Avoid – the coating can keep flaking from the damaged areas.

Updated from your answers.

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

Where a coating is already damaged, cavitation has an edge to work on. Ultrasonic cleaning does not remove scratches either.

Do this instead

  • Wipe with a lens cloth and cleaning spray
  • The frames can be run if an optician takes the lenses out
