Ted If the residue is clear, don't bother, you might create more damage than you realise (ESD). If the residue is brown, you've been using the wrong solder. If you really feel the desire for aesthetics then you can can brush it with IPA, but beware ESD if there are sensitive components on board. Also beware some components can dissolve in some cleaners, eg old style polystyrene capacitors.
