Tight Ignition Switch

I noticed that mu ignition switch is a little harder to turn both on and off. Is there any lube that could safely be used to free it up a bit.

Lock Ease....Apply just a small amount (1 short spray shot) from the aerosal can into the ignition key slot or a few drops from the liquid bottle on your ignition key, then stick the key into the igntion switch and turn it back and forth slowly. Lock ease can be found at any auto store. wal marts etc... Mind as well give both door locks and the hatch lock a shot of it while you at it too!
