construction is it? I normally clean keyboards with
soap and water in
the kitchen sink, scrubbed with an old tooth brush, after it's been
dis-assembled as much as I dare. I then blow out as much water as I can
I normally take them apart as much as _I_ dare, which may be a lot
further :-). In particular, I pull all the keycaps (after making a
diagram of their positions) and clean them with one of those foam cleaner
sprays.
In one case, where I had a lot of keyswitch problems, I even desoldered
all the keyswticthes from the PCB, took them out of the frame, took the
PCB off the frame too, and then took each switch apart and cleaned it.
That's a lot of work and may well not be worth doing in all cases.
