How do you remove bad odors from a car?
Make sure the car is empty and clean. I use vinegar and water mix to wash off areas in the car–including the seats, dash and so on. If the odor remains, go to an auto upholstry shop and ask them to spray their enzyme spray that eliminates odors. It didn’t totally remove the sour milk smell from my car (a gallon of milk leaked on the rear seat), but it certainly made it manageable.
