I have an NMO magmount which has a bit of corrosion on the threads and the part
where the antenna makes contact. The threads of the antenna also are a bit
corroded. Can anyone recommend a good cleaner/method to remove this corrosion?

I used steel wool and WD-40. It really works great.

Hm, I've used WD-40 on everything from 115 VAC power switches to VHF
slug-tuned inductors, potentiometers, and relay contacts. Whatever
conductivity it might have, hasn't been a problem for me. I wouldn't use
it on 100 meg level impedances, but more from worry that it would pick
up dirt and grunge.

What sort of experiment can you suggest that will demonstrate and
perhaps allow measurement of its conductivity?

Uhm, spray it on the tongue and "taste" 9V battery and compare to no spray
"taste"? :-)

Sorry, couldn't resist to repay earth Chi.

I'd just stop at the grocery or hardware store and pick up a can of
Brasso. Shined up my old brass military buckles very nicely, and
should do a fine job on whatever metal your antenna is made of.

It removes the corrosion very easily with a rag, and doesn't harm the
skin.

I seen a dumbarsed backyard mechanic spray it on his AM car radio chasis
(inside) to 'clean out the bugs and stuff'.

Never worked again.

So I don't use it on electronics.

And I've used WD-40 in and around ignition components on several
engines and fired things up a LOT better than with the water that
was previously there.

I suspect WD-40 conducts no better than white kerosene.

It may be better to live under robber barons than under omnipotent moral
busybodies. The robber baron's cruelty may sometimes sleep, his
cupidity may at some point be satiated; but those who torment us for our
own good will torment us without end, for they do so with the approval
of their consciences. -- C. S. Lewis

We are discussing RF components. Not High Voltage spark coils and plugs.

No, we were discussing the conductivity of WD-40.

If you think WD-40 has a characteristic that affects "RF components"
and not "High Voltage", you aren't talking conductivity. And in
reference to your other message regarding a car radio, it is not
conductivity of WD-40 that is/was the problem.

WD-40 will change the dielectric constant of air-gap tuning
capacitors, as will anything other than air. Even the residual film
left behind can have an affect. Perhaps it could mess up inductors
as well, but I've not experienced that.
