It's probably too late now, but try searching the fine SMTnet archives. Trust me, there have been LOTS of discussions about stencil washers here.

Your aqueous (spray) and ultrasonic methods refer to cleaning of the stencil for storage between jobs. All others would be most common as in-process cleaning methods, whether with cloth or paper products.
