How do you neutralize perfume odor from a cars seats?

I've done this for doggy smell. A bowl of ammonia. I put a bowl on the front floorboard, turn the a.c. On, close the windows and doors. About 10 minutes. I do this a few times during the early evening. Leave the bowl there overnight. Remove in the morning, open the windows, run the air again, for a few minutes. Works like a charm.
