What's best to use? Especially keen to get all the white polish residue off and stop the plastic from fading in the sun.

The best is GTechniq C4http://www.theultimatefinish.co.uk/gtechniq/c4-permanent-trim-restorer.aspx
Clean with neat APC or IPA or both before you use it
Other products are available, but will need reapplying regularly, this doesn't need that
