Find a dirty part that needs cleaning. Put it on a stand outdoors. Stand upwind and squirt away. In the new environmentally correct age, I'm sure that we are not supposed to do things this way, but people seriously used to get used carbon tetra-chloride (which is what I'm pretty sure is what they used in these extinguishers) from dry cleaners (they don't use carbon tet any more) to use for parts cleaning. No one seemd too worried about it at the time.
