BTW, methyl ethyl ketone is MEK. Denatured alcohol can have "nasties"
albeit in small quantities. Ethanol evaporates too fast to be better
than MS for flux removal IMO. While fast evaporation is necessary for
cleaning surfaces like glass to prevent smearing (methanol is the best
here), a more balanced solvent is better suited for heavy deposit
buildup. Furthermore, MS plus compressed air will evaporate almost as
fast as acetone, in other words you have control over the rate of
evaporation.
