Quick question, if there is only dust on the car from a couple of days, can't you just hose the car down and get all the dust particle off and dry it with a drying towel?
I only see the point of washing the car, if there is water spots or excess dirt, but if it's just a little bit, I'm pretty sure you can just hose it?
