For bug removal on my polished Sonex, i use Nuvite's bug remover. it leaves a somewhat protective surface.
As to washing. If well polished, so that the surface is closed it will resist spotting quite well, I have had no problem with plain water wash and ordinary car wash detergent (nothing super aggressive) and airplane belly wash for oily bottom of fuselage.) Just do not do it in sun or on hot day, so you have time to towel it dry. You may have something in your water that attacks aluminum, check small area first. First year in hangar, surface got dull quite quickly. By second or third re-polish, surface was closed enough to be very durable. (Has been a couple of years now, and is due for a re-polish.) If you have yours in a hangar, keeping dust off it helps preserve finish. Dust holds condensation. I have covers made by cutting up and duct taping together WalMart's cheap picnic table covers with soft underside. A few elastic straps and very small patches of Velcro in out of sight locations keeps it in place, and can remove in about a minute, and reinstall in 2. Materiel folded and taped to form pockets for wing tips and horizontal stabilizer tips. (Also sign on wing that states "I am not a picnic table, Keep Off.")
