Last spring I bought some Rain-X windshild washer fluid...worst stuff ever once the sun comes out. Noyjong but a dry haze smear on the outside of the glass. I've changed wipers, scupped the glass with ammonia and newspaper, but now pumping out that orange stuff to make room for the old fashioned blue "blinker fluid". Anybody else hate a dirty windshield and got tips how to clean or prevent one??
