Improvised air freshener
It’s nice when your car smells good, but good car fresheners can be expensive, and some of them actually have a very strong smell that is not very pleasant in small quarters. So, you end up paying for something you will throw out of the car quickly after buying.
There is a simple hack that can solve both problems. Puncture a few holes in a mason jar lid and add some scented candle wax to the jar. When the car’s temperature gets high enough, the wax will start to melt and release a subtle aroma.
