I live in the Pac NW, and off a half mile, un-maintained dirt/gravel road. Washing my car is useless, unless I want to take pictures in my driveway. By the time I get off the gravel and onto pavement there is a fine layer of dust covering the car and the whole rear bumper is dust brown in color. If I wash in the city it gets fuxxed when I go home. I let rain wash my car, unfortunetly it has been about 3 months since it last rained here...
