If you rode over it with a fender then you saved your leg from having dog crap flung all over your leg but the poop can still be lodged in the fender, under the bumpers and in the wheel (if you have a treaded tire). The best way I remove poop is either of two options. 1: Ride and continue to ride until its worn off or 2: Brush it off with a small brush. I always have a handheld brush in the trunk of my car to clean the debris off my board. Its an essential item you cant go without.
