I suspect that using a detergent would be a really BAD thing to do. You
don't want the water "wetter" and work into the dip switches...we have had
good results for the past ten years with just a 50/50 vinegar/water soak
for about ten minutes (after the scrubbing & fizzing stops), then rinse
under the hot water tap for a few minutes-but we have very pure tap water
here in Vancouver-and blow dry after shaking off the excess water.

Mind you if the board's traces are corroded, you will have a lot of trouble
arresting and bypassing the corrosion. It works under the "Resist" film on
many boards and continues to eat away...also you get the corrosion working
it's way into the IC's by crawling up the metal legs and slowly etching
into the chip. You can almost hear the IC's screaming in agony late at
night...Sounds like a "B" SF movie, eh?
