Leaves & pine needles and other detritus in my cowl or hatch area are the bane of my existence! My wife rolls her eyes when I stop to pluck a leaf off my windshield or from under the wiper arm before getting in the car. Luckily we both park inside at home and work, so this needs only infrequent attention.

Excellent point to check your drains. First see if they drain before worrying about trying to clear them; they may be fine.
