Summary
For over 40 years, the electronics industry has been seeking ways to determine an answer to the thorny old question: How clean is clean?

Meanwhile, others were plotting ways that they could monitor the quality of their production process with specific regard to the presence of ionics (salts) that conspire to cause circuit failure.

They figured that using a blend of alcohol with de-ionised water would be an ideal medium, measuring its conductivity before and after.

Why Alcohol? Because conventional rosin based fluxes used at that time were soluble in alcohol.
Why water? Because salt dissolves in water.
