As soon as I saw these little guys, I knew I'd have to turn them into little people. 

It just occurred to me that this would be a great lead into an article all about cleaning solutions. What to use, what not to use, nib maintenance, and how to get rid of caked-on waterproof ink—now, that might be quite interesting and informative. Just the kind of thing I should be writing.

This is not that, sorry.

Still, maybe one day. But for the record, 50% water and 50% isopropyl alcohol for an everyday slosh. Acetone (nail polish remover) is great for all those hard-to-clean bits. Use wisely; it can be unpleasant to work with.
