After the board is built, water soluble is not a good idea. The joints
will tend to corrode, and I don't like the idea of putting my K3 in the
family dishwasher for a complete rinse...
I use plain old tin-lead rosin-core solder for SMT rework on my K3. I
sometimes use "no clean" flux rather than rosin core. Depends on which
spool is nearer when I do the re-work. But I carefully avoid the spool
of water-soluble flux which I use for prototype construction.
The regular solder will alloy with the solder on the board, no problem.
