Re: the small brass stampings -- a possibility In a situation I was involved with, a company was cleaning motor windings to remove lights oils and the like. These had extremely tight spacings where water with its surface tension has a tough time getting into, surfactants notwithstanding. In order to eliminate the Freon cleaning, which worked so well, the company ended up going with a high flashpoint hydrocarbon solvent (an Amoco product) similar to mineral spirits in a modified degreaser with ultra-sonics. This worked well, but had to change the processing a bit to allow for longer drying time.
