15: An Old-Fashioned Air Freshener
There are a few interesting methods that you can use to make your car smell better inside. We covered dryer sheets earlier in the list, but did you know that an old candle will work too? When the car is parked in the heat of the day, the candle will begin to melt in the jar and its great smell will resonate throughout the car. If you have some old candles lying around that you can use for this, it will work out well and the smell will be excellent (via Family Handyman). It doesn’t get much easier when it comes to turning your car from funky to fragrant.
