Vaseline Tip
Vaseline has been one of the best lifesavers for generations. Not just for colds and flu, but for pretty much anything. Have you considered using it for the interior of your vehicle? If you have vinyl or leather inside, apply Vaseline to a cloth or cotton wool and rub it all over the car to keep the leather from splitting. Vaseline can also be rubbed on rubber door seals to keep them from freezing in the winter.
