Most homes have some kind of doormat at the entrance, so people can wipe their feet before entering. But there’s no such thing as a car doormat. Whatever is on a pair of shoes is going to get inside your car. When you consider how often we go into and out of our vehicles in just a week, it’s no wonder that the interiors are often, well, filthy. Add in things like a pet, snacking, trips to the beach, or parking on mud or dirt, and our car floors and seats can become fairly disgusting fairly quickly.
