[MRCA] Cleaning Query

[DSP3]

Gentlemen,

I acquired an ARR-15 HF receiver, recently.  It came from a dealer in 
the vicinity of the famous Bone-yard.  That is, out there where the old 
military aircraft are stored and cut up. Anyway, this radio came out of 
a P-2V and has been stored a very long time.  There is a coating 
(dusting?) of exceptionally fine southwestern desert dirt throughout the 
radio.  It comes off quite easily with paper towels, Q-tips, 409, and 
such.  Below is bright metal, with little or no evidence of corrosion of 
any kind.  The front panel is gone, marking-wise.  I can re-paint and 
dry-transfer new markings OK.  The slight panel dents and deformations 
can the re-shaped, as necessary, with a set of milled IBM heavy metal 
blocks.  My question is, then, what's the best way to clean the 
dust/dirt out of this thing without damaging the typical Collins movable 
coil racks and such?  High-pressure air will probably take some of it 
off but.....  the dirt has permeated the radio pretty well.  
Fortunately, there are covers over many of the critical areas but the 
wind, I assume, eventually gets the dust into everything.  The thing is, 
I've never had to wholesale clean a unit this dirty before.. just lucky, 
I guess?
