Laundry sheets and bugs on the front cap.

I always make washing the bugs from the front cap as part of my setup procedures. Even love bugs will come off if you soften them up with water and then a scrub brush. Takes around 15 minutes. Simple Green is a great cleaner but will take the wax off. The ideal situation is a heavy rain storm around 15 miles from your stop that stops as you pull into the cg. Most all bugs come off between the rain and the air hitting the front of the cap.
