I am fairly new to fabric covered airplanes. I was curious what method/chemicals you guys use to clean your Ceconite/Randolph coated airplanes? I'm worried about the paint when cleaning bugs off the leading edges and such. So far I've just been using Plexus and a microfiber rag that is no longer suitable for the windshield since that's what's on my bench but that Plexus is expensive! Thoughts??
