"proper" contact cleaner works better and doesn't pick up contaminants
like WD40 does.

But, of course, you must use it
vary sparingly.

Indeed, and at the force it comes out of the can, that can be tricky.
Spraying it into a small snootiness and using the tip of a screwdriver
to transfer it works. But for pots, switches, etc., it's still better
to use contact cleaner made for the job.


Exactly. I would never use WD40 on an electrical/electronic device.

Correct..Servisol is the way to go. But if the track is worn or
damaged then replacement is the only long term solution.
