I tried the McGuiars plastic cleaner... it worked for about a week. Then Chrysler installed vent kits... the headlights started to fog up all the time. The last day of my bumper to bumper warranty I went in and convinced them to order me new headlights. Then they scratched the hell out of my bumper when they replaced the left headlight... had to send the car to the body shop for repairs. Sheeesh. Anyway, the scratches are fixed and I love my nice clear headlights.
