I have had my car for about three years now, ever since i have bought it, the can has had a distinct odor, it smells like crayons. At first, i was in belief that the smell would go away as i owned it. The smell still roams around, even after 3 years. I came to the idea that the previous owners young kids may have put a crayon down the air vents. Does anyone know of a way that I might be able to cover up the smell? I've tried numerous ways to rid of it, but it just comes back. Thanks.. Created by Kyle. cars-transportation-en - maintenance-repairs-en

If there's a crayon in an air vent, then no matter what you do the smell is going to come back, you'll need to use your nose and figure out which vent it's in and take the grill out so you can try take the crayon out. Anything you do will only mask the smell on a temporary basis until you've removed the source of the smell.
