I agree on both counts. Scotch-brite pads work well for cleaning up
old tubing. I have built many large homebrew Yagi's using old 6061
aluminum tubing. Steel wool can leave metal partials embedded into
the aluminum that can corrode, Scotch-brite has no steel. After owning
a station in Aruba and seeing the effects of severe corrosion, I try
to avoid unnecessary dissimilar metal contact. Aluminum and copper
are not close together on the galvanic table. I know that some of the
big multi contest stations are using copper anti-seize on their
antennas but I use Penetrox.

I would not use *either* steel wool or copper bearing anti-seize. Both
copper and steel will set up electrolysis with the aluminum that will
cause future conductivity and mechanical problems.
Stick with thee scotch pad and an anti-seize made specifically for
aluminum.
