Febreeze or any other fabric cleaner won't do anything if it is just sprayed on whether aeresol or with a spray pump.
I was offered $50 when one of my friends gave up on fabreezing and even trying to mask it with putting a 3 pack of air freshener trees on the rear view mirror. I own a hoover steamvac, I used the stair/upholstry attachment and went over it, afterwards I left the windows cracked to let everything dry and to let lingering smells out, the smell was 90% gone when it was dry and completely unnoticable in a week as the ceiling fabric couldn't be steam vacuumed(febreeze on that a few more times maybe?)
IMO the best way to do it with little or no effort is to leave the windows open all the time for about a week, it will probably only get about 50% of the smell out in the first week though, but it's a start. If you can put a little effort into it and can find a steam vacuum, try using it, just make sure you test for colorfastness, both my car and my friends car were fine, but check this one to be sure.
