♦ The trunk: Your trunk is probably your go-to option for things that you’d prefer to keep out of your nose’s reach. Unfortunately, your trunk is still connected to the rest of your car. Those smells that once existed in the trunk are only going to spread so it’s best to remove everything, vacuum it out and, if necessary, try the baking soda and interior wash approach.
♦ Other potential offenders: To remove all odors, you’ll need to clean out some of the forgotten spaces of your car, like between the seats and windows. You should also address the obvious spots, like cup holders, seat pockets and seat belts. It’s likely you’ve been sweating on your seat belts every day, so they, too, are worthy of a spring cleaning.
♦ Air filter: Finally, you should change your air filter regularly. The filter traps dust, mold, pollen and other contaminants, and prevents them from entering the car, which can cause musty odors and other smells. As with any filter, it needs to be changed on a regular basis, roughly every year.
