If you were to guess where the germiest place in your car was, you would probably be wrong, according to a new CloroxPro study. According to the research, most people think frequently touched items like the steering wheel, the driver door handle and the gear shift are the germiest places in a car. The study, however, revealed the germiest places are more unexpected; the germiest areas are the front seat cup holder, the dashboard air vent, the driver side floor mats, and the trunk of the car. Comparatively, the steering wheel and the interior door handle did not have as high a concentration of germs as previously assumed. So, before your Memorial Day Holiday trip, you might want to clean your car, paying extra attention to the areas you might not have considered before.
