Urban Legend of the Week

Hand sanitizer may combust if left in a hot car.


A fire district in Wisconsin posted a warning that clear plastic bottles left in your car can act as a magnifier for sunlight, and potentially start a fire. They later warned about keeping hand sanitizer in direct sunlight, for the same reason, adding that hand sanitizer is flammable. Several news stories picked up on this, reporting that hand sanitizer left in a hot car  may combust. This was combined with an image of a melted car door, which is not linked to hand sanitizer or clear plastic bottles.

This fire department later stated that the warning was intended to be about leaving clear plastic bottles in sunlight, not exploding hand sanitizer. Hand sanitizer in and of itself will not explode in a hot car.
