I also thought of that later. I've used Goof Off on plastic medicine bottles, plastic spray bottles, my Malibu's interior surfaces, and other than marring paint have been unable to find any plastic that was adversely affected by it. Obviously caution must still be used.
Another 'idea' is WD40 applied gently.
