2004 grand cherokee,film build up on inside of windshield,do not smoke in car, no a/c/leaks,no heater core leaks, when cleaned off it reappears the next day. also have not treated the dash with any armorall or such

New car snot...every brand new car I've had gets this. From what I understand (don't know if it's true or not) it's just all the vapors from all the new plastics and whatnot secreting (for lack of a better term) and they cause a film. I just clean the inside of the windshield with rubbing alcohol and over time it dissipates. Be patient, it'll go away in time.

Ha.......funny, but I'll buy that. Makes alot of sense.

I know it sounds far fetched and bizarre, but it's true! Every car I've bought brand new does this, and it takes a few months but it eventually goes away. I have a new Wrangler Unlimited and it's doing the same thing. Pretty wacky, but its gotta hold some merit.
