Ugh. I would never recommend using WD-40 on electrical contacts in
fine electronic equipment. It gets gummy with time, and attracts
dust. It may make things better in the short run but I fear that if
it's left in place it may cause further (worse) problems.


Agreed - WD40 is good for de-gumming your chainsaw, preventing rust on
garden tools, and freeing up rusted bolts, but thats about it. BP
grade isopropyl(sp) alcohol is readily available from chemical
suppliers - (A litre bottle will last you for EVER) - if you do insist
on a "tougher: lubricant, then CRC 2-26 is pretty good. BUT - as in
everything else - RTFM before you do ANYTHING!

"TFM" for WD-40 is at:
http://www.wd40.com/Brands/wd40.cfm

The website enthuses about all the uses of WD-40, including that it
"dries out" electrical systems. (Recall that the "WD" stands for "water
displacement".)

But even on their own site, I couldn't find any word about WD-40 as a
switch cleaner and contact lubricant... and that speaks loudest of all.
