Yup, have used it and it is good.  CRC has a chemical for cleaning too.  My
major concern is that folk will generically use contact cleaners without
actually knowing that fuses and the like are actually connectors.  Switches
can be cleaned, but then again, there has to be some wiping action, which
most switches do not have.  Unfortunately manufacturer designs switches not
to wipe, so they last longer.  Tarnish and corrosion then set in and the
darn thing fails sooner than if they had wiping actions.  Not to mention
pitting, once they start to fail...  There is another product for variable
resisters like volume controls and air position sensors.  It is a pretty
good "stop gap" solution for intermittant radio controls and sensors, but
has to be sprayed directly on the carbon track.  It does work, have used it
for years on noisy radio controls.  Check the can and be sure that it is for
controls not switches.  In the old days we used "carbon tetrachloride" (just
tapped the shop fire extinguisher), but that wrecks your liver and can
actually be absorbed through the skin.  Illegal and dangerous!  

Here is one for the general group!  I have a number of associates that
actually grease the lamp socket base.  They swear that it keeps the moisture
out and prevents rust.  I have no emperical data to confirm this and really
don't have the guts to try an experiment.  I have noted however that some
cars (especially fords) have a type of white grease packed into the
connectors.  Unfortunately every time I have seen this material it is
because I have been replacing the device, so I don't know if the device has
failed due to it or whether it is just a normal failure.

Tom, who has been up working since 5:00am and is now ready to go out and
play.......
