Really tough luck for this Canadian man who had the unfortunate experience of waking up to find his vehicle had not only been broken into by a black bear overnight but a family of opportunistic skunks had taken up residence using the open window to gain access.
There are several different methods utilizing common household ingredients to neutralize and remove skunk odors from upholstery but it is a long and stinky process. Skunk smell is extremely potent and persistent can last for weeks or even months if left untreated.
If you live in black bear country you are likely aware they prey on unattended vehicle with even the slightest remnants of food left inside. To avoid situations like the one above, all food or anything that smells like food should never be left in cars. This includes used wrappers, pet food, and even scented items like sunscreen, lip balm and air fresheners. Also all doors should be locked and windows rolled up fully.
