How to make your car smell good
Hang an air freshener in the car.
There are many types of air fresheners that are designed specifically for cars. To pick a scent, simply find one that appeals to your sense of smell.
No matter what kind you get, be sure to place it in an area that gets lots of airflow, so that the scent circulates throughout the car. Vent clip and dashboard air fresheners are meant to be clipped to or positioned over the vents.
