One way to really cut down on clean up is to wax your monokote type of covering. I don't think people take me seriously when I say that, but it makes a big difference in clean up as when you wipe the oil comes right off. Also, the wax keeps the covering shiny and protected from scuffing and the minor surface scratches that cause it to look dull after a year or so. But clean up from glow fuel and bugs is a major plus.
Auto wax works good. But, I use a product call "Gel-Gloss," available in the shower/tub cleaning section at most hardware stores. It is a crème formulated for fiberglass, plexi, plastic cleaner and polish. Makes the shine on Monokote look inches deep. The polished finish is so slick most everything wipes off easily with a moistened towel.
Good stuff for polishing canopies and painted parts too.
