I don't know wheter cleaning the lux off helps or not. I tend to do it because it looks neater but I don't know if there's a real reason for doing it. I've seen plenty of boards in electronic appliances with small amounts of flux still left on the joints and it doesn't do any harm. I was under the impression that flux only acts as an acid when it's liquid. Which is generally the case with acid base reactions. Try mixing citric acid and sodium bicarbonate powder together, notice how they don't react? Now pour on water and watch it fizz.
