[sdiy] Cleaning question and felt question

[Brice D. Hornback]

When using Kester 331, I use an old toothbrush and lukewarm water (too warm
and it can warp your PCB).  The organic flux foams up nicely and cleans
easily.  Also, you should always do a final rinse with distilled or DI water
after cleaning.  Not only does this rinse away any minerals that could cause
problems... but also prevents water spots from forming.  Once you've used
Kester 331... you'll never go back to anything else.  It's awesome!

After the PCB is cleaned, I then use Kester 245 (no clean) on the hookup
wires, pots, etc.

Note: some parts should *not* get wet.  Make sure to solder these onto the
board *after* you clean, rinse, and dry the board.
