Is it OK for your ultrasonic cleaner?

Fountain pen: nib and feed

Yes
Check first
No

Modern nibs and feeds come out clean of dried ink.

Updated from your answers.

A few questions to be sure

Is the pen older, or made of celluloid, ebonite or wood?

How to do it

Time
3 min
Water
Lukewarm, 30–40 °C

Flush out the ink first. Only the nib, feed and grip section. Rinse until the water runs clear.

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 writes that ultrasonic cleaning is unproblematic for modern writing instruments but is advised against for celluloid and wood. Manuals list pen nibs as suitable.

Watch out for

  • Celluloid, ebonite and wood: avoid
  • Do not leave the parts in for too long
