The endpoint of all washing is the same: elimination of all put a trace amount of hypo.
No method produces a better result than another because all methods are run until the goal is achieved.
One can minimize either the expenditure of time or the expenditure of water. As a practical matter, as most people don't have laminar flow equipment:
- If time is of the essence then the better method is a continuous vigorous flow of water with some mechanical flexing of the material;
- If water conservation is more important then the better method is a series of agitated soakings.
