[Elecraft] Cleaning a K3

[John Severyn]

I will second Dick's caution of using any high pressure air or gas.  The 
high flow rates can cause static charge buildup on higher impedance 
parts, causing over-voltage failures.  Keep the flow rate and pressure 
low....do not use an air compressor hose. The static buildup can happen 
no matter if the hose is conductive or insulating.  The flow of air over 
the component leads generates a static charge.
