Clint, I have rarely found a need to clean the rosin - it doesn't conduct and causes no harm other than asthetics. If you feel you need to do it, alcohol is relatively safe (use Isopropal in the highest concentration you can get) - but keep it out of components like unsealed inductors, relays and such - the alcohol WILL attract water vapor from the air, so expect some condensation on the PC board and work in a small area with a Q-tip or similar swab-type tool.
