RE: What mixture do you use to clean your plane ?
After you have used what ever snake oil of choice or even just wiper her down with a rag. Spray her down with Lemon Pledge (or the store brand equivelent silicon furniture polish) then lightly buff with a clean rag.
You will have discovered a shiny new airplane at for the outing to the field next time. absolutely will not loosen film covering. Hmm its also ideal for full scale canopies and windsheilds, works better than the traditional packaged product for aircraft window cleaning.
