Hurry throw a pitcher full of water on top of it! Oh wait it's not on fire and you arent docsmarts
Febreeze will do the trick for the outside, as for the inside you can't do much but just let it air out by itself. You could try wiping most of the surfaces on the inside with alcohol, being totally careful and making sure it's totally dry next time you turn it on. I wouldn't try wiping anything on the motherboard pcb or anything you think would get damaged. The case is the only thing you can really safely clean with alcohol and any other cleaner.
