I leave the windows open all day and all night and remove the seat covers plus the carpet of the interior. It's a very serious job and my stomach is aching because of that bad smell. Right now,the smell is still there but just on the lower portion of the car,under the seats.I really dont want to ride on my car right now. I ordered new set of seat covers to replace the old one. I sprayed another air freshner today,I hope it will be removed before saturday because my cousin will used it as their bridal car.
