PCBs that have solder flux all over them need to be washed in solvent (
ie denatured alcohol) after being washed in hot water .

as the perfect answer.

Years ago, we washed loaded PCB's in de-ionized water, then to accelerate
the drying process dissolved a bit of that water off the board with
alcohol. Later we found that inundateing the electrolytics with alcohol
did something to them that sounded a 'deathknell' for them over time. In
otherwords, the boards died a premature death, albeit a clean death.
