Defrosting windows

Well, the standard "blue" windshield washer fluid usually includes around 33% methanol, so I guess your 25% solution isn't going to be particualrly damaging. However, I have never had much luck using "blue" washer fluid to keep a windshield clear on a cold morning. If you spray enough of it on the windshield you can clear the frost, but as soon as you start moving it reforms. The only sure way to clear the frost is to get the windshield temperature up above freezing. Oh how I miss the Insta-Clear Windshield I had on my 1986 Sable. Now that was a great solution to frost. Hit the button, wait a 20 seconds, and drive! Second best solution was a block heater. I suppose a remote starter is also a great fix -I am planning to install one on my daily driver soon.

You might also want to consider Prestone Windshield Deicer. See

If you use Rain-X, frost is much more easily removed.

I used Rainex once. What a mess. It MIGHT be alright if the rain is very heavy, but in drizzle... it leaves a smear across the windshield. I had to resort to a mixture of Bon Ami and Brasso to get rid of the stuff.

It usually takes more than one application to get a uniform covering with RainX. It does tend to squeak more in light drizzle, but I prefer a little squeak to not being able to see diddly-squat in heavy rain.

I had good results from using RainX windshield washer fluid. It keeps a constant recoating on the windshield.

You move the wiper so that they are in vertical position?

Before using Rainx, I advise a search of dejanews for "rainx +problems"

I know that will bring up postings that mention "no problems", but don't use Rainx without checking things out.

Warm water, or even cold water.

Frost scraper would be my suggestion - really can't leave home without one during the winters here..
