Barry and the group,
It depends on the flux. Most flux that you will run into is RMA (rosin
mildly activated). This can be removed with a flux cleaner specifically
formulated for to job, or by denatured alcohol. This is not the 70% that
you get at the drug store. You might be able to find 91% at the drug
store. THis is fine. You can also get denatured alcohol at the paint
department of your local store. If you get into a bind, Vodka or everclear
from your local spirits shop also work fine. If the flux is unknown you
mighr want to try water first. There is a noclean flux that requires
special treatment to remove. If you start to see a white liquid when you
apply alcohol, you have a noclean flux. Do not go any further with the
cleaning unless you want to get the correct chemistry or you want to use
lots of alcohol.
I usually tilt the board against something on the bench with some paper
towels under the edge of the board. I then apply alcohol at the top of the
board with cotton swabs. This lets the flux saturated alcohol collect on
the paper towels. I continue with the alcohol bath until the board is no
longer sticky.
Hope this helps
