I started w/ paper towels and Windex and it was streak city. Then I tried the Windex with a nice microfiber towel and still got mild streaks. I bet I cleaned every square inch of glass four times!
The only problem with newspapers is the ink comes off easily which can be left on plastics, rubber, and fabric. I use paper shop towels which I don't think work quite as well but at least no ink is left behind.
I went to Safelite/Elite Auto Glass store and asked for a spray can for free. Got home and tried it on all of my windows and boy I was so impressed. :yesyes:I'mma go back over there and ask for another one when this one runs out. lol
