absolute ethyl alcohol because it was readily available to me.
Denatured alcohol would probably work just as well, as would 100% IPA
(isopropyl alcohol), as has been already suggested. But, the latter
is hard to find locally. That is probably because it is not as good
an antiseptic as 50% or 70% IPA, which is the usual consumer use for
it. Come to think of it, E95 might work too, but I haven't tried it.
I think keeping water out of the solvent is probably important,
unless the flux is water soluble or you use heat and a detergent. John
