Gravity is something I use too, although, I hadn't actually thought
about telling people about it.  Something else I use is centrifical
(spelling?) force.  I put the board on the end of a rope and twirl it
around....well okay maybe not, but.........  I firmly grip the board,
with two hands on larger boards, and swing it back and forth to get as
much of the water off as I can.  Obviuosly, board size/construction may
hinder this.  This gets rid of the bulk of the water before I put the
board, standing on end, in front if the fan.  Oh, and I haven't
accidently thrown a board yet :-)
One of these days/years I'll write a faq about cleaning computers.  I
should proabbly order some Alconox, since that is something I haven't
used yet.

  Fact 4:
 Use gravity! When you take the PCB's out and place the boards vertically in a
 warm dry environment, most of the water will run off. Every now and then
 you can turn the boards so that it can run-off water from another angle.
 This is a very important aspect of the dry-ing procedure for a lot of the water
 will have to be dislodged from under various components on the board
 like chips, capacitors etc.
