I save the spray nozzles from the various spay cans and clean them out with a thin pin and lacquer thinner if necessary to have spares for clogged nozzles. 

If you have a hard to find paint spay can that clogs up on the inside or the gas is gone and paint is good inside you can puncture the can on the top with a small nail covered by a rag in case some gas is still pressure.  Then pour out the paint into a jar and save for use in an air brush to paint with.
