[Milsurplus] Disinfecting electronic artifacts

[Ralph Cameron]

Our local Cold War museum has a very large loading coil used with a 
former LF antenna but housed in a fiberglass case approx. 7ft high by 6 
ft long and 5 ft wide.
The fiberglass hut was hit by lightning at some point and has a foot 
diameter hole in the roof. The coil has been sitting there for about 50n 
years but its not known how long ago the hut was hit.

In order to remove the coil which sits in an abandoned farmer's field it 
is necessary to disinfect it so no insects or bugs are brought into the 
main museum. The coil is wound with Litz wire about 3/16" in dia and 
spacing filled with cotton string. Other than appearing somewhat ragged 
and dusty it doesn't appear contaminated within and creepy crawlies.

Any suggestions for cleaning /sanitizing the coil.  Compressed has been 
suggested. Anyone have experience with same.
Thanks
