[Milsurplus] Cleaning and "polishing" aluminum...

[Kenneth G. Gordon]

I want to clean up some really dirty BC-454/455 receivers, the all 
aluminum ones. Very fine steel-wool and lots of elbow grease do a 
good job, but I am getting really short in the elbow grease 
department what with my Rheumatoid Arthritis and all.

Is there some easier, better way to accomplish the same thing? 
Buffing wheel and compound or some such? I tried using a cotton 
buffing wheel and rouge, but that didn't cut the surface oxidation.

Suggestions from the collective wisdom gladly accepted...and 
acted upon.
