There are/were many flux removal chemicals available,
but in today's over-protective society they're hard to
find. I treasure my stock of triclorethelyne (SP?). (:-))
"Rubbing alcohol" and a small stiff brush work well.
I place a paper towel on the board, between the brush
and the board, to soak up the freed resin and prevent
it from running all over the board.
An ideal brush is known as an "acid brush" and is available
at welding supply stores. It has a rolled sheet metal handle
and stiff bristles that can be cut to shorter lengths to make
the brush stiffer. A fist-full of 'em is cheap. In other stores
they may be sold as "glue brushes".
