My understanding of the washing soda is to raise the pH for saponification of fats and other non-polar compounds to dissolve in water. Saponification works best with more basic solutions which is why lye is used in soap making. By reducing the pH by adding vinegar you're neutralizing the washing soda to a degree because it reacts to create water with carbon dioxide and sodium acetate which overall makes a less effective detergent
Raising the pH helps with the detergent action, also the washing soda "softens" the water - calcium and magnesium in the water form carbonates, replacing the sodium in the washing soda.
So we're in agreement?
