Before resorting to the more dramatic methods, you might try just driving
the car for a bit with the clutch depressed. First start it in neutral to
get the engine warmed up a bit, then turn it off, select first (or reverse
if you need to get out of the driveway), start it in gear and away you go.
The vibration from the engine will sometimes knock them loose.
Mine let go before I got to the end of the driveway.
