You might want to try Plexus. It’s a cleaner and protectant made especially for plastics like Monokote. I tried it once on half of my plane just to see and it made the clean-up a bit easier, just not enough to justify the continued use – in my opinion.
By the way, those of us living in the beautiful People’s Republic of California appreciate hearing the opinions of those living in some of the backwards states from time to time. Thank you for your words of encouragement. It’s nice to know that our efforts aren’t going unheeded. Maybe if we can just get some of those other backyards states to turn around their thinking we could all be living into our 90’s.
