Be careful about dishwashers and _old_ electronics: (pre Epoxy B) silicone
IC packages (usually gray 70s vintage) are very succeptable to damage from
moisture incursion --> corrosion. That being said, I wash (newer) circuit
cards all the time in hot water, a little detergent, and a toothbrush.

Actually a lot of the new soldering processes for the surface mount stuff
we do use a water based flux, and are water washed as the standard
