Keepin' it clean.

[Muse]

Okay, I have noticed lately that I can clean the rear window of my wagon, and after a mere 24 hours, it's completely filthy, able to write in the dust dirty. Anyone have any tips on keeping it dust-free, apart from wiping it down every time I fill up at the gas station? I'm not much of a stickler about the cleanliness of my car, but dirty windows drive me batsh*t.

its aerodynamically deficient. Best you can do is wax the crap out of it.

You could get the dust deflector (its a spoiler) for the back that will run wind down the back of the car.

This. The dust deflector (tho a good idea) will only keep %50 of the dust off
