Freshen up your vehicle with diffused scented oil bottle. When you get your freshener, unscrew the cap, pull out the little stopper & put the cap back on. Tilt the bottle for just a few seconds and you will see it start coming onto the wood. Hang it up and you will soon have a great smelling car! Re-tilt when the scent fades, it will need this to keep the smell going. Length of use and scent throw varies based on weather, season, how much you tilt it, etc.
This is not essential oil but it is fragrance & base that is Phthalate free.

Important!!! And trust me from experience this is not a "just in case" caution. This will happen if not properly used.
This oil will mess up your dashboard or anything it drips on. Do not, I repeat do not let it hang uneven or tilt the bottle too long causing drips. If you do, clean it up immediately! After my first incident, it has never happened again because I was aware of this so I want to warn you like I wished I was.
