Hi Jacqueline! The dreaded white residue huh? YUCK! This seems to be a ongoing issue...probably because there are many different things that can possibly cause this. There's a real good article about the different causes of this problem at Kest

I have experience to the Kester 2331 water soluble flux long time ago with white residue and it related to the solder masking. Check what kind of the solder mask and ask Kester to do the test for you. Rgds.

White residue remaining after cleaning circuit board assemblies can be caused by a variety of chemicals and reactions. Rosin and water-soluble fluxes, circuit board resins and epoxies, component materials and other contamination all contribute to this complex chemistry. This paper discusses many of the sources of the residues that seem to be an ever-increasing occurrence.
