I've always sucked at cleaning car windows; I dunno why, I just can't ever seem to get it to come out without streaks. So I finally managed to get it right once, and then I left an unopened can of soda in my car (black interior, windows up, yay!) and it exploded like a fucking claymore mine -- all over the windshield and both front side windows. (don't ask me how it did that, I wasn't there.) The plastic and fabric was easy to clean -- a bucket of hot water and ammonia worked wonders. But the glass -- the glass was a different story. I've cleaned it five times now, with ammonia, Windex, 409, even paint thinner (in case there was any oil on the glass), and it still looks like shit. I've used paper towels, newspaper, microfiber glass-cleaning cloths, everything I can find around my house to wipe the shit off, and there are still smudges and streaks all over the goddamned place. I have to drive with the A/C on constantly, because if I don't the humidity from...me, I guess...will stick to the glass and make it almost impossible to see. Please help me.
