2000 Concorde invaded by mice

This winter I left my car outside for about two weeks without using it. In that time a group of mice decided to make it their home. I set traps and I think I caught them all. Problem is that when I run the defroster, the car has a very mousey smell. It doesn't smell like a dead mouse, but rather like a hamster cage that hasn't been cleaned in a while. Any ideas on how to get rid of this smell? Thanks
