[Hallicrafters] Chassis Cleaning ... etc.

[Rich Oliver]

The best way to start is to blow it out with high pressure air.  It is 
good to do that outdoors if possible so you get rid of the dust rather 
than just redistribute it to your other radios.  If you do not have air 
in your shop it is worthwhile dragging the set to a place that does.  Be 
careful around delicate parts like dial pointers, meters, and the guts 
of IF cans.

Please keep us posted on your progress.
