We've been taking ours to a touch car wash with high-pressure air drying. It's been nice for keeping the salt off it in the winter and the 17-year cicadas off of it in the spring thus far. I can be in and out in 10 minutes which means the van stays cleaner than if I were only washing it when I had the time to do so by hand in the driveway. A client built a house with a many car garage, one of which is setup as a car wash station -- all indoors so no heat, no time pressure, you can wash you car at 10pm if you want to and nobody cares. Plus you could mount a TV out there and make an evening of it. That's the way to go.
