A lot of times, it collects on the rear bumber/trunk, and the clay seems to take it out. It's little black and/or rusted dots. It's either road dirt, or something from the exhaust on the rear of the car. The ones on the top surfaces, most often times it's from being left outside or under a tree. The clay usually gets it out. Try that first.
