I am quite concerned about all the aluminum cleaning chat recently. It is  
well known that any of these abrasive cleaners and pads will leave  
micro-scratches in the aluminum surface. Due to the skin effect at our high
the rf flow will encounter a maze of conduction channels that not  only will

increase the electrical length of the element, can reverse the  electron
creating pattern nulls in some directions.
The only approved method of restoring beam antenna appearance and  
performance is replacement of the aluminum tubing. 
You can find a complete selection of NEW virgin aluminum tubing at great  
prices at _www.texastowers.com_ (  under the
"aluminum". With these low prices and availability, there is no reason  to 
even think about any other restoration method. Who wants to be caught
aluminum when you could be hamming it up instead?!
Please let me know what you need!

SCOTCH  BRITE or similar nylon scouring pads and water.  Pads usually found 
at  home improvement stores.  Why mess with WD40, kerosene, etc that create
mess and then must be cleaned off. Use wet scouring pads.  I keep a  bucket
water to soak he pads.  Rinse with water and wipe dry with  paper towels or 

A nice clean dull non-reflective surfce.   The antenna just became a bit
invisaible by not reflecting  light.

BEEN THERE, DONE THAT  on all my antennas.

Another  aid in the process; keep a beer handy, though do not wase it on the

aluminum.  And for the UK folks a substitute pint of bitters.  Ah,  yes,
memories of plowman's lunches while traveling in UK.

DO NOT  do this process on the concrete patio or drive way.
