So what are you guys using to get rid of the dreaded inside of the windshield haze that builds up over time? This happens to all cars for course, but my Sport had it bad when I bought it (didn't notice at the dealer, who supposedly detailed it). I've tried a bunch of different products and techniques over the years, but none of them seem to leave the inside of the windshield perfectly clean. I recently cleaned the inside of mine meticulously with RainX wipes (made for the inside of the window) and microfiber cloth. I basically scrub every inch with the wipes, then use a robust paper towel to clean off the excess liquid. Then I scrub the dry surface with the microfiber cloth. I did this whole process twice, but then this morning in direct sunlight, the windshield was full of smears and streaks. I actually pulled over in a sunny spot and tried to chase down the streaks with the microfiber cloth that comes with the car, but it still isn't truly clean. Any suggestions would be greatly appreciated!
