Is the crayon smell many describe in our Crossfires a very sweet smell......sort of like someone spayed a strong sweet air freshener into the air vents? I asked the last owner of he did this to my vents to cause this smell and he said it was like this when he got it. I sprayed alcohol into my vents and the smell went away for a month, then returned. Not really sure what crayons or burnt crayons smell like. This is very sweet smelling. Comments appreciated.
