According to CarsDirect, the first step is to thoroughly vacuum the car's interior, making sure to access hard-to-reach places where smelly debris might be.

Unpleasant car smells can come from air conditioning or heating ducts, so spraying a deodorizer through the car's intake valve can be helpful.
Sprinkling baking soda on the carpet, rubbing it into problem areas, and vacuuming it a few hours later may eliminate odors. Charcoal is often used to absorb smells in air and water filters.
