You can get something called meguairs Quik Detailer and use it after driving. Be sure to use alot of it and buy some good Micro Fiber towels.. It may cause some swirls if the dust is bad enough. Wouldnt be a bad idea to clay the paint also.. That will give you alot more shine and a smoother finish..
There is something called QEW which is a way to wash the jeep without water. You can research the stuff here:
Autopia.org
Have fun detailing!
