Yes I have! But do have a bottle (OTC sized) of both in my trunk. I'm speaking though of spot cleaning, usually not the entire vehicle.
What I do with very light dust is first remove it with one of those little dusters that you can find in the home cleaning section of say Lowes or Home Depot. Then take some bottled water on a MF towel if the paint is warm. Then turn the towel over, spray some UQW on it and apply that way.
I don't spray it, (or UQD) directly on the paint. If it's more than a light dusting I'll probably use ONR spray and several towels. Then follow that with UQW, or 156. (Also in my trunk)
Did forget to mention DG151 and have become a HUGE fan of it since Dad07 sent me a sample earlier this year. Man that stuff is slick!
