Will adding Dawn dishsoap to the windshield washer fluid help cut the winter grime from windshield? How much do you add?

I would not add any Dawn dish washing soap to the windshield fluid. First you will get a lot of bubbles and soap film. Second, there will be a build up of soap scum in the small hoses that run from the fluid reservoir and then the washes will not work until the hoses have been replaced. You don't need to add alcohol as the washer fluid is a combination of water and alcohol. If you want to clean the windshield with Dawn mix some up in a pail with water and use a squeegee by hand.
I agree, do not add dish detergent to you windshield fluid! You could damage a lot of parts and end up costing more than a lifetime worth of buying windshield fluid! Buy yourself a squeegee like they have at the gas station, and just clean your windows periodically. If you are out driving, and the car is warm, just toss some clean snow on the windshield before you get out, run the wipers, and that helps, too.
