   I have had mixed results cleaning certain j-wire keyboards.  Some, 
like my Pro-One and PPG, just refuse to stay cleaned for any lenght of 
time.
   This is why I went through the trouble of "Polyfusion-izing" my 
Pro-One.  Since I couldn't keep the contacts free of dust and oxidation 
for any given length of time, I replaced them with magnetic reed switches 
and now I have no more troubles!
   I _did_ make sure to leave the original wires in place should I have 
decided that I didn't like it and want to remove it.  :)  It's also a 
very tricky process to get right, so I don't really recommend it unless 
you 1) really love that keyboard and 2) aren't going to sell it to anyone 
else.  :)
