I can't believe this! I just bought a nice, used '06 lease return convert. v6 at a great price from a dealer about 60 miles north of us. BUT, when they detailed the car prior to letting me drive it away, the dumb %^$&%^#%'s who did it sprayed the windshield with the same liquid detailer they were using on the body. I didn't think anything of it at the time as they really did-up the body paint real nice and thinking I could easily re-clean the windshield when I got it home. HOWEVER, I have used all the auto glass cleaners I have and even Windex with ammonia, then PURE ammonia, and the stuff is still on there. I'd drive it back up there an' give'em hell, but I don' wanna waste the time and gas. Did this stuff get BAKED on when I drove the car back down on the freeway for the 60 miles on a nice, warm day? WHAT else can I use to remove it, short of taking it to a glass shop and spending $$?
