[R-390] Cleaning modules

[Cecil Acuff]

I've used the original Formula 409, a brush and the garden hose.  I blow the 
modules off with my compressor carefully and let them sit in the sun.  Then 
they go back inside where the A/C pulls the rest of the moisture out of them 
for several days before applying power.

Works great.

Be aware that Simple Green that is not fully washed away reacts with 
aluminum.  Guys were cleaning up in the airframes of General Aviation 
aircraft and corrosion problems started occurring.  It has been pretty well 
publicized in those circles to stay away from Simple Green for that reason.

I wouldn't worry as much about it in a radio but make sure you rinse 
extremely well!
