[Elecraft] Those nasty little rosin spots

[Don Wilhelm]

Clint,

I have rarely found a need to clean the rosin - it doesn't conduct and
causes no harm other than asthetics.
If you feel you need to do it, alcohol is relatively safe (use Isopropal in
the highest concentration you can get) - but keep it out of components like
unsealed inductors, relays and such - the alcohol WILL attract water vapor
from the air, so expect some condensation on the PC board and work in a
small area with a Q-tip or similar swab-type tool.

73,
Don W3FPR
