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.
