Do a forum search for "geo" method. Many threads and posts on it. Basically 2 cups of liquid (some use powdered) Calgon water softener dissolved in a gallon of hot water and added to both tanks. Use tanks until full and dump as usual. Some will suggest also adding laundry detergent or Dawn (original) to the black water tank. We carry both the Dawn and Calgon and Happy Camper and use them on occasion. Most of the time we use nothing. For the black water the real trick is to dump, back flush until you run clear and clean and always start with lots of water - couple, three or four gallons in the tanks after dumping.
For bug removal on front end I use 303 Detailer on the glass and the Diamond Shield. It works well for easy cleaning / bug removal and the DS still looks like new. I recently learned of einszett products and have purchased the Windscreen Clear and Anti-Insekt Bug and Tar Remover and plan to test them sometime in the future. Also recently heard that making a Baking Soda paste for bug removal. Haven't tried it but it has a certain logic to it.
