I have read several posts lately that refer to frost in the morning. Some say it's such a problem that they have to warm up the engine before driving off, wasting loads of fuel in the process. (Not to mention that it's not so good for the engine to warm up that way!) There is one solution that has worked quite well for me and I hope it can solve the problem for others: de-icing washer fluid. I've been using it for about a year and love it. The brand name stuff is a little expensive but works the best. (Rain-X brand works best for me, available all over the place.) It's basically standard washer fluid plus glycol, which is the same stuff used to de-ice aircraft. Melting power is much better than the regular blue fluid, and re-freeze resistance is also really good.
For a light coat of frost I start by scraping the rear windscreen and side windows, at least partially. Then I hop in the car, hit the washers with the de-icer, give it a few swipes to clear, then start the engine and drive off. The rear defroster takes care of whatever is left out back once I'm underway. The procedure for very heavy frost or very cold weather is about the same, except that I scrape the windshield first and then use the de-icer to clear the rest and prevent new frost from forming over the first few miles of driving.
I used to warm up every morning and it destroyed my gas mileage. Think mid 20s. Never again! I hope this advice is helpful to some of you.
