Like Y2K3SRT says, dust first if not too dirty with a California Duster, then follow with a product like Speed Shine from Griots or Meguiars Quick Detailer. You can wash it with Griots or Meguiars car wash, but must rinse and dry inside a covered space. The first method works best and most often for me. Be careful with the wheels, as they will scratch very easily. Check out Griots car detailing guide, it's a good one.
