What's a windshield wiper fluid that doesn't leave so much residue. I bought the rain-X fluid and it leaves this sticky residue all down the side of the windshield and sprayed across the top of the roof. The windshield is only clear where the wiper blades clean and everything around it has this foggy look to it. It's annoying as hell. My wife is pissed also because I had put some in her car as well (doh).
