Would like to suggest that one NOT use steel wool to clean aluminum joints
on antennas. The steel wool will 'shred', 'disintegrate' and imbed minute
particles in the aluminum... and eventually will rust and set up a high
resistance joint. EVEN when using the conductive greases and
anti-oxidants... Pentrox, etc.
Suggest using a product made by 3-M and it is called Scotch Brite pads.
Paint & body shops use it in place of sand paper in a lot of instances.
