Remember that hurry you're in? Think about how long that ice is going to take to COMPLETELY scrape off your car windshield.

Try either of these two things:

1.)  In a spray bottle mix distilled vinegar with just a little water. That will prevent most ice build up from happening on your windshield before a big storm. Simple and easy to do. Also, do this for your shovel too!

2.) Get an old box and unfold the cardboard and toss it under your windshield wipers after each time you get out of the car.
