[Antennas] Cleaning aluminum

[Christopher Boone]

In cleaning aluminum oxide, I have used floridic acid (used in water of 
course) to clean AC condensor coils...it really cleans the elements on 
DB420s that were heavily oxided and salted by being near the Gulf of 
Mexico..one of them I cleaned 10 years ago still looks brand new in the air!

There are probably better solutions now...but I used a little heavier 
concentration than what is normally called for and let the stuff do its 
foamy job....worked great for me!
