As anyone got any ideas of how to remove Turtle wax from rubber trim and the spoiler on a 360GLT.

an eraser sometimes works good just an ordinary stationary eraser

It could be that the wax has chemically changed the plastic/rubber, otherwise you could just scrape it off. You could try white spirit or cellulose thinners. WD40 sometimes restores plastic/rubber, but you can get specialist rubber/plastic renovators.
