I'll second (third?) everything that was said.  Every time I've tried to
skimp on washing after using a Kester flux pen I've regretted it.  I use
hot water, dish soap and a toothbrush, followed by compressed air to speed
the drying.  Where I used to work we had a can of some kind of solvent that
worked faster and dried faster but I never bought any myself.
