Laundry sheets and bugs on the front cap.

The cleaners that work well to remove bugs are more than likely going to strip the wax off too. Less wax, more stubborn the bugs, the more cleaner, less wax left on, the cycle gets worse.

Use a good wax then wash with a non wax stripping soap & water.

Bottom line, there is no easy way to deal with bugs on the front cap though washing them off before they bake on real good helps.
