a high ammonia content cleaner. Rense and Vac excess water and dry by leaving open on a hot sunny day (hehe, that'l be a while!). Then use lots of freshner. To vac up hard to reach areas modify a vacume hose tube with some clear air line (also helps to see the progress). Throw some open boxes of arm and hammer in the car until your ready to do the job. That will help suck up the smell.
