Made Good Glass Cleaner....and It's Cheap!!
 

I was in a pinch so I used some windshield washer fluid (blue stuff to below 0). Worked good, no streaks.

Water is pretty much the main ingredient, but has methyl alcohol (methanol) added to keep it from freezing.

You can make your own as well.....

1 cup rubbing alcohol
1 cup water
1 tablespoon vinegar

Repeat as needed for additional amount..

Instead of using some fancy rags, give newspaper a try to clean and dry your windows.
Its slightly abrasive surface cleans windows very well.

Works amazing. Screw window cleaner...one wet piece of newspaper and one dry piece. Used to do this on a paper route.

Thanks for the info.
