Using this Hybrid Racing Awesome Sauce Air Freshener is a breeze. Just place it in your race car or near your gear. For best results, keep it in a well - ventilated area. When it comes to maintenance, there's not much to do. You can replace it once the scent starts to fade. One thing to note: keep it out of reach of children and pets as it's not for consumption. That's all there is to it, and enjoy the great squash scent!
