[Elecraft] kx1 - flux cleaner

[John, KI6WX]

Bill;
This subject comes up on the reflector every few months, and sometimes
sparks a good debate.  There are two good choices:

A commercial rosin flux cleaner designed for use on electronic circuit
boards.

Anhydrous Isopropyl Alcohol (at least 99.9% pure).  This does not contain
any additives that might leave a residue on your board that might be harmful
in the future.  Drugstore alcohol and that sold at home centers is rarely
about 70% purity.

If you do this procedure, use Q-tips or equivalent to clean off a small area
of board at one time.  Do not pour the alcohol on the board or you risk
carrying the flux into mechanical components that can't tolerate it.  Don't
tell Elecraft, but I do clean my boards.
