Snow can do a number on a car and Inside Edition has useful tips to help you in the wild winter weather. Ordinary household items like hand sanitizer can get you out of a jam when your locks are frozen. If you put a little hand sanitizer in the key lock on the door, it works like salt on the road and does not freeze the hole. Sandwich bags can be placed on the side mirrors to prevent them from freezing. An onion or a potato can stop your windows from icing.
