Readily available in the UK is Fluxclene from Electrolube, which is
specifically designed for cleaning flux off pcbs. It would see that
our USA cousins have not heard of it...
Perhaps from working a long time in a military environment, I always
clean flux off boards after soldering. It makes the whole job look
far more professional, and although flux (from NORMAL solder that is)
does not do any harm it certainly looks awful.
