It seems the key is to wash them off at the end of each day's travel before they bake on, However, there are bug and tar removers sold in auto supply stores that are petroleum based, but I have been successful in first applying lots of water to re hydrate the splatters then applying some good quality car wash soap straight on a wash mitt. By rubbing with a mitt rather than a wash brush I find I can remove all remaining bug splatters.
I gave up health foods... at my age I need all the preservatives I can get.
I use Dri Wash n' Guard on our coach and never have any difficulty in removing the bug collection. I will generally clean the windshield at the end of the day if the bugs warrant it. I normally clean the rest off the front when we arrive at our destination. All I have ever used on this coach is Dri-Wash.
I use Korkay, Takes bugs off very quickly. I spray the area and let sit for a minute, then wipe off. You will have to replace any wax/treatment you have done but it really removes almost anything from the surface.

Go to WalMart in the auto section and buy a gallon of Super Clean, get a handheld sprayer, wet the front of your coach down and spray undiluted solution on coach and let set for about 5 minutes. Get a soft brush along with soap and water and easily remove bugs. Best stuff I have found for bug removal on a coach.
