Disinfecting Pens

[srvrf]

Being new to pens and being in the health care field, I thought I'd ask if anyone has had any information as to which methods are preferred to disinfect/clean their pens? I've used alcohol wipes and foam but we've got some stronger agents as well. My general feeling is that most anything should work and not damage the resin but I thought I'd throw it out there and see what you guys think.
