Be sure to clean the wiper blades themselves to get a nice clean windshield.

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.

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.

When I used the windshield washer system on my car last winter (ice condition weather), the water on the windshield became ice very soon. Now what kind of alcohol can I mix with water and at what percent?
I find methylated spirits does the trick for my windshield washing as to what strength just keep trying till you find the right mix our winters here in the UK are not as harsh as the USA.
