I read not too long ago, in Byte I think, that it is possible to wash a keyboar
d with water. (i.e. submurge it to help clean out internal contamination) I ha
ve an XT keyboard with a barely functional control key and an F3 key that is be
ginning to go and I am thinking about doing this. (I am told that you submurge
the keyboard in water (after unpluging it, of course) agitate the water a bit
and then dry it with a hairdryer on its coolest setting. This is supposed to c
lean the contacts and remove accumulated dust and dirt) My question is, has an
yone else done this, did it work, and would you suggest that I give it a swing.
Any questions, comments, or help would be greatly appreciated. I read my mail,
on the account listed above, pretty regularly so a reply, if warranted, will c
ome soon. Thanks in advance.

According to information that I have 'cleanliness' will affect reliability... As long as you completely dry out the PCB and (very important!) the mechanical switches, you will be fine... Don't submerge the entire keyboard - just the PCB. And leave it 'drying' overnight after blowing it dry with the blow dryer (although I personally use a fan to dry off my PCB's since I don't have to sit I can grab the PCB and turn it all around, and then leave the thing sitting for a few more minutes...) -- Joseph I.
