Hahaha, sorry man, but that's funny ritch there!
I honestly think the only thing that's gonna get it out is fresh air. Similar incident... ha,
well our door in our dorm room this year was extremely heavy (The hydro arm was way too powerful) so I decided I was gonna fix that. :
I locked the door and climbed up on a chair to have a look at it. I loosened one screw and then noticed the "fill" label under it, so I decided that was not a good one to be unscrewing since I didn't want to mess with the fluid. So I find the one that looks like the strength adjustment, and I go back to the other one to screw it back in. About that time my roommate lays into the door (the lock didn't do its job) throws me off the chair and when the door swung closed the pressure blew the screw out and hydrolic fluid went all over the wall and into our closet. That smell was horrifying, ha, just like gear oil. All we had was water and Goo Gone. It smelled for about 3 days and then went completely away.
Jimmy, you know how far our room is from the front door. People were walking in and saying, "what is that smell?!" haha
It should go away in time. If you've hit it with all the cleaners you've got, there's nothing more to do than roll all the windows down, fold the back seat down, leave the trunk up, and drive the crap out of it ;D
