I used Rainx x about 8 years ago on one of my cars and swore the stuff off because of how hazy the windshield got every time I used the wipers. I decided to give it another try, thinking that they may have changed the formula, but the haze is still there. Is there a good way to remove the Rain X and is there something else I can use that will allow the water to bead off and not cause the haze?
