Customize your own car freshie kit! Pair your favorite fragrance oil & car freshie, making the perfect combination to love wherever you go. Or if you already have a car freshie, just pick an oil refill! Fragrance oil will take finish off of wood and your vehicle dash, so please follow directions carefully. * Lay down wax paper and set your freshie on top. * Place 4-5 droplets of fragrance oil on the front and back of the freshie. * Let the freshie air dry until the oil has soaked into the wood on both sides. * Hang the freshie in your vehicle to enjoy! * Put the lid on the oil bottle tightly and store in a safe place in an upright position. * Repeat every3-4 weeks or as desired. Make your vehicle smell great again with a Dirt Road Candle Co. car freshie.
