2 solutions.
One is called wax blaster

(Bottom of page) Have just bought some, but haven't used it yet.
The second solution, and this is not a joke, but rub it with smooth peanut butter!!!!!!! I have seen this on a few international websites. Literal rub the affected trim, wait and then wipe off in one direction. I have never tried it, but others swear by it.
Which ever method you use, once done, protect with a vinyl/rubber protector. I prefer Autoglym.
Good luck!
