Could you use an aquarium pump and a long airstone / bubbler to help clean
the boards using aeration? Or, maybe get in there with a Waterpik?

Hi, all, thanks for all the suggestions: alas, they won't really help
with this part of the problem, since the gap between the PCB and the pin
contact housing blocks is only about 1mm (less in some cases) and
there's no way I know of to get any kind of effective brush into a gap
that small.
Maybe something akin to dental floss, but that would be about it.
(String might be a good idea, it has a rougher surface and might be
better at removing impacted grime, plus it's wider, so will do more
width on each pass.)
The Simple Green might be something useful to add to the bath, though. I
generally use compressed air to dry boards (although I've heard rumours
of possible static problems from this, I've never had a problem), which
is easy for me since I have a 5HP compressor in the basement. It mostly
blows the water (along with any dissolved minerals, although I usually
try and finish with a douse of distilled) right off the board.
