You will wonder why you’ve never thought of this before! Its so easy! But, you do have to plan ahead. If you suspect there will be a snow or frost overnight, here is how you can avoid wasting time and being subjected to freezing temperatures in the cold, dark morning.
You may hold it down with windshield wipers or a brick, rock, board or other heavy object on the roof of the car.
In the morning, simply whisk away the tarp. The snow and ice will go right along with it. Beneath the tarp, you will find a perfectly ice free windshield.
Now you can drive away with warm fingers and get to work 10-15 minutes earlier.
