If you're concerned about the components on the board, and you well should be,
in this case, then you can clean the board step-wise, first dusting it with a
hair brush (I use a shaving brush) and then attack the sticky grime with a
strong sprayable detergen, focusing the spray on the board so as to avoid the
components that might be affected by moisture or detergent, thoroughly
brushing and subsequently rinsing the board with plenty of quite hot water.
Older sweep circuit boards such as what you mention seldom have particularly
static sensitive parts on them, but they do frequently have pot's, etc, that
won't benefit from residue of detergen in them. You can clean the solder-side
of the board with alcohol and wash and rinse it with the same procedure.
There may be better procedures and practices, but I've found that to be
adquate for monitors, keyboards, etc. If you have a compressor, that might
help in removing water from the component side of the board. I can't
recommend that for current-generation, CMOS-laden boards.
