thanks Paul,
I read so much here on bad techniques (mainly cleaning) that I thought it
might show how it should be done before someone make a muff of it.

blowing the water off straight away is the key. leaving it to dry will
certainly cause contamination depending on the amount of water remaining.
the suggestion of washing a board and leaving it for a few days sends
shivvers up my spine. :O

it also helps to spray the plugs and sockets and switches etc as they tend
to hold water in them even after blowing dry. the CO Contact cleaner is
designed just for that purpose. I even used it a few times to restore faulty
key switches on a //e, just spray heaps of the stuff into the gap where the
plunger enteres the switch and hammer away at the button until you get it to
work. blow a bit of air in after to remove the excess and any crap that may
be in there. saves desoldering the board too which is a bonus on those
keyboards.
