After driving the Dempster Highway, 1000 mile dirt road, you have to wash your car right away. They use some sort of caking agent on the road to keep the dust down. The problem with that is when it rains that stuff mixed with mud forms a concrete on your car and if you don’t wash it off it will dry and pull the paint off. There is only one car wash, well not really a car wash, just a pressure hose in Dawson City. A short video of washing the Dempster off of the Jeep.
