[Antennas] Cleaning aluminum antenna parts

[Don Havlicek]

Using Scotchbrite pads seems to be the easiest and least destructive 
method.  To clean the interior of the tubing, a strip of a pad can be 
cut and wrapped around a much smaller diameter rod [wooden, aluminum, 
whatever] and pushed inside the tubing and rotated.
I would NOT use PENETROX .. it has a tendency to harden .. that would 
make future work nearly impossible.  A better product is Noalox 
[available at Lowe's or Home Depot] .. but make sure you get the correct 
version .. aluminum/aluminum mix only.
There was an excellent conductive material available years ago .. called 
CualAid ... [Cu=copper, Al=aluminum] and it worked with either/both metals.
Good luck
