I have met Don Aslett, the cleaning guru, several times. (He lives in ID). Twice it was in the airport in Boise when we sat next to each other. Now this guy is somewhere between a little OCD and a lot OCD, LOL. However, he told me that whenever he gasses up his car, he cleans it out while waiting for the pump to finish. He keeps a cloth in the car to dust the inside. This is all well and good if all of your crap is garbage--and some of mine always is--but harder if you are driving around with stuff that you either don't want to put away, or don't know where to put it.
