Is it OK for your ultrasonic cleaner?

Pen body (celluloid, wood, resin)

Yes
Check first
No

Modern materials are often fine – celluloid, ebonite and wood are not.

Updated from your answers.

A few questions to be sure

What material is the pen made of?

How to do it

Time
3 min
Water
Lukewarm, 30–40 °C

Modern materials only. Short time, then rinse and dry.

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

fountainpen.de advises against ultrasonic cleaning for celluloid and wood, and hard rubber discolours easily. Modern acrylic and metal pens handle it better.

Watch out for

  • Celluloid, ebonite, wood: avoid
  • Lacquered pens can lose their lacquer
