[Elecraft] Cleaning a K3

[Clay Autery]

As I originally said, "NOT recommending this because it requires a great
deal of

care/experience"...

I use 99% Iso. Alcohol when necessary.  And I'm not saying to flood the board with it.  Also not saying to get it near enclosed components...  One should use proper instruments and care when utilizing ANY solvent, TO INCLUDE water... which BTW, is the "universal solvent".

73,
