Water Wash Flux
Before no-clean fluxes became the most commonly used materials in wave soldering, water wash fluxes had an extended run as the preferred material. The advantage of water wash fluxes is that they can be formulated to be very active so that they can solder virtually any assembly without a concern for reliability, since the residue will be removed after the soldering process. The disadvantage of water wash fluxes is that assemblers must have an additional piece of equipment, the water wash system, to remove the flux residue, and must deal with the effluent.
Neutral pH fluxes can generally be left on the circuit board for extended periods of time before washing, while the "low" pH fluxes generally solder somewhat better.

Fluxes are available in 1-gallon and 5-gallon containers, and 55-gallon drums.

When you focus on trying to quantify the level of contaminating material that remains after the cleaning process, you leave the more important question unanswered. What is that question?
In this installment of Tech Seconds, Phil summarizes the two primary criteria for selecting a wave flux.
You shouldn’t base your solder flux selection on just one data point.
