Well, if you can get them apart, then it is pretty easy.
generally, rubbing alcohol works pretty well.
If you can't get them apart, then you can dunk them in a
little vial, like a pill bottle from the pharmacy, with
alcohol in it. Then, if you have one available, set that in
an ultrasonic cleaner with water in the tank. This will
help work the solvent into the capillary channel in the
tip. It may take a long soak and repeated runs of the
ultrasonic cleaner to free it up enough to get the plunger
out of the tip.
If these are all metal pens, you can be a bit more
aggressive with solvents.
