I have a feeling that this is a dumb/paranoia post but it's been bugging me. Hear me out.
So I got a 15' Jetta GLI last month from Cowell VW in Richmond. It's new but a last year model that's probably been sitting outside for a while. They let me pick it up on the same day so I understand that they didn't do a good clean. The back window has been dirty since I picked it up and I got around to washing it this week since the car was shiny for a while. I cleaned the inside and outside of the window with a car window product from Canadian Tire. Next, I washed the car and scrubbed the window very well from the outside with a sponge. I was surprised when I looked after it dried that it was still very dirty. It's like a coat of dust but it doesn't come off.
The gunk is on the outside because if I use a towel and windex a spot for a good 1-2 minutes, I get a clean spot the size of a thumbprint.
Few questions:
1.) Any idea what I can use to clean this stuff off? It looks like a dusty windshield but I have no idea why it's so difficult to remove. I guess I can drive it there and get them to clean it but I'm also paranoid about #2:
2.) I'm assuming this stuff is covering portions my car. You can't see it on the paint but when I pop my hood, my engine cover and various plastic parts under the hood are super dusty as well with this sticky stuff. I've seen dirty engine bays before, but on a car with less than 1000km it's a little surprising it's that bad. Should I be worried about it getting into engine components and intake stuff?
Thanks

Those guys rock.
