On the occasions when I've used WD40 on pots, fan bearings etc, it
hasn't caused any subsequent problems.

"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.

Unfortunately, the last time I saw my Electrolube dispenser (with the
pull-out nozzle) was over 40 years ago - but I've always got some WD40
(or similar) at hand. Actually, white spirit etc also works, and has the
advantage (or disadvantage) of eventually leaving no lubrication.
