Take leftover/used franganced wax and place it in an old butter tub (small one) and poke tiny holes in the top. Put it under the car seat and in the summer months the melted wax smells great in your car.

This is a good tip. When we rented a car, the dealership placed some sort of freshener in a tin that had holes in it in our center console. It smelled nice and wasn't something hanging from the rearview mirror.

I've been thinking about a way to do something just like this.....I wonder THIS never crossed my mind....:confused:
