2. Fill a sock with coffee
Love the smell of fresh-brewed coffee in the morning? Keep that pleasant scent lingering all day by creating a coffee air freshener for your vehicle. The folks at Instructables suggest taking a sock (or two) and filling them with coffee beans or even ground coffee.
Tie the sock closed, and put it under the driver’s seat. If you have a second sock, stick that under the passenger seat.
If you don’t have a spare sock on had, a bag would work as well. Coffee beans in a paper bag is one of the clever ways flight attendants use coffee to banish nasty smells.
If you simply can’t get enough of the smell, you can duplicate it in your home. According to Instructables:
“[I]f you are looking for something pretty, then try this same thing only instead of a sock use a decorative bowl and only use coffee beans. In my office I have a bowl that used to have spare change and now it’s home for a half a bag of coffee beans. It makes the entire room smell amazing.”
