Re: (ET) Penetrating oil & conductivity

It's not like WD-40 is an insulator of electricity, just a silicon based 
water displacing liquid.  I've used WD in a lot of different electrical 
things and never had a problem.

According to their website:

WD-40 - A Great Contact Cleaner

Controls and switches in electronic equipment can and should be cleaned 
and lubricated with WD-40 to keep them working properly. Just spray some 
WD-40 into the control or switch, and work the control back and forth to 
say goodbye to scratchiness and intermittency. Always make sure all 
electrical sources are turned off before spraying WD-40 on any electrical 
switches or components.

I've been wondering about this for a while.  I had to
squirt some screws & studs to get wires off, but I
became uneasy about the residue.  If it's
non-conductive, won't it interfere with the
connections?  If it's conductive, couldn't it short
along the drips & runs?

I remember hearing about spraying WD40 into
distributors to displace water, and I was always
suspicious of the same thing.  How could it be
conductive enough to not interfere with the points,
yet not short out to the rest of the inside of the
dist.?
