Another almost-myth, IMO.  Simple Green is quite alkaline, and long-term
exposure to it can promote relatively minor corrosion in aluminum.  So the
"trick" is to be sure that all of the SG gets flushed away, especially if
you are using it on thin sheet aluminum.

The FAA banned its use on aircraft because it was seeping into the joints
and staying there.
