2 Ingredient Homemade Car De-Icer Spray - 1/3 water to 2/3 rubbing alcohol (91)-in spray bottle
Never use hot water to de-ice car windows (doing so could crack them). Instead, smack your hand on the hood and trunk to break up sheets of ice, and (as long as the exhaust pipe and radiator grill are clear) start the car and turn on the heater and headlights. Or, keep a small spray bottle filled with 1/3 water and 2/3 rubbing alcohol in your car, and spray directly on your windshield to melt ice in seconds.
