My description of the science at work here? Ear wax is acidic by nature, that's how it protects the area from bacteria. And ear "wax" is hydrophobic (it doesn't like water), so its coating keeps the ear canal free of bacterial breeding dampness. The white vinegar is simply helping to restore a high level of acidity while the alcohol dries up any water.
P.S. prior to learning this trick I used to use Hydrogen Peroxide with mixed results. After learning more with age I realized that the Hydrogen Peroxide, after oxidation, leaves behind water, aka a damp environment for any residual bacteria to flourish. Using this 50/50 of vinegar & alcohol mix post a hydrogen peroxide flush yielded desirable results every single time. Soon I totally left out the hydrogen peroxide step. Oh, and never cover your ear after flushing as that again inhibits the dry environment required to put an end to the bacteria.
