9: An Old-Fashioned Air Freshener
What if we told you that there was another way to get great scents inside of your car? It involves a mason jar, candle wax, and some holes in the lid. The wax will begin to melt from the daily heat on the inside of your car. After a while, you’ll smell the wonderful scents permeating throughout your vehicle (via Family Handyman).
This homemade air freshener will last you a lot longer and the smell will be more impressive. Store-bought air fresheners never work longer than a few days so it can be a pain to have to replace them over and over again. The mason jar method allows you to repurpose old household candles and get a renewed scent out of them.
