[Elecraft] K3: Brush or Blow Dust?

[Geoffrey Mackenzie-Kennedy]

Stewart,

To remove dust and dead beasties from circuit boards, I use the type of 
vacuum cleaner that you describe powered by DC, which I was lucky to be able 
to buy at low cost in Luxembourg many years ago. To clean other parts of my 
equipment I use the vacuum cleaner and a 'make-up' brush when required, 
which has very soft and small diameter bristles, 'acquired' from our 
daughter before she used it (I did ask). I do not use liquid cleaners nor 
'wipes'. Fortunately spiders have never managed to get into the sensitive RF 
circuitry, which is contained in metal enclosures/ boxes.

73,
