to pull out the whole interior, seats, carpets, panels, and clean it out that way. to make sure to get all the moisture out from under the carpets as well. i can say from experience that works. my first car got flooded one time cuz the moonroof was open and it rained HARD. it smelled like a stale armpit smeared with gym socks. i opened all the doors, took out the whole interior and left it in the driveway for two days in the sun. it all dried out. no more stank.
