[Hallicrafters] Chassis Cleaning ... etc.

[Rich Oliver]

Mike,

I'm going to stick to my guns on this.  Dust tends to be abrasive so it 
is important to remove as much as possible by non-contact techniques. 
 This is particularly important for plastic surfaces.  As for 
localization of dusty areas, my experience suggests that if dust is 
noticable somewhere there will be some dust everywhere.  Every time I 
blow out a radio or other device I stir up a cloud from the expected 
spots, but nearly always also stir up a cloud from somewhere I didn't 
expect.

I suggest blowing off as much as possible then vacuuming with a soft 
brush.  Only then go to wiping.

73, Rich
