Buy the de-icing washer fluid instead of the traditional blue type. It works.
there are a few ways to get ice off or even not have any ice at all on your car windows. <br />
1. use cold water on your windshield while the defroster is on<br />
2. use cardboard to cover your windshield during the winter. it will help keep ice from forming on the glass.<br />
3. park inside a garage
hmmmm.....interesting. I will have to try that :)
