Best spots for scents

Once a car owner decides on a fragrance, it's fairly common to focus the scent underneath floor mats or seats. However, Pietro explains that the best method of spreading a scent throughout a car begins outside of it.

"Put the scent on the outside of the car by the windshield wipers, on the vents, from the outside, and turn the air conditioner on in the inside," he said.

Pietro said that allows the scent to blow throughout the vehicle evenly.

"Doesn't get anything wet, and it blows out the smell," he said.

These techniques are all dependent on having a clean car to start, Pietro said, meaning those with odors that just won't go away will need to deal with those problems before moving forward.
