There really isn't anything in spray shellac except alcohol, shellac and propellant. It should eventually soften back up but I'm not sure about the nozzle, I would guess you need to soak it in alcohol and or blow som air through it to clean it out.
Some spray cans seem to have a use me once "feel" about them, they never wamt to work as well the second or third time.
