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.

One of these reflector topics which won't go away...
