[Elecraft] K2 Cleaning PCB

[Stuart Rohre]

Rick,
Either don't clean, or if you have some excess flux, the alcohol method is
the least intrusive one to K2 components.  Most of us do not clean any more;
instead I use Multicore solders, which have 5 tiny cores of flux and do not
leave gobs of flux like cheap solders do, (and some well known expensive
ones).

Most of the joints you will make, if made with care will not require
defluxing. You can do more damage than good with solvents and board
cleaning.
