My first rainy day in the Bay Area since moving out here. I think the area needed the extra water! This is my first high end car, so I'm trying to learn how to take care of it (and its paint) properly. My car (white) now has the usual brown dirt water marks along the doors and side panels from driving around on a rainy day. If I don't have time to wash the car entirely, I was wondering after a day like this, if it's best to: a) Hose the car down and let it air dry (I would definitely not towel it dry given dirt will still be present). or b) Just let the dirty water dry on to the car. I would be using your standard hose water No fancy distilled water. Thanks for any feedback.
