As we know the plastic chrome trim does get tarnished,after lots of investigating i used the following.

1. microfibre cloth with white vinegar gently wiped gets ride of most of the build up

2 hard to shift bits,very very light rub of AUTOSOL with microfibre

3 Wipe off fully and gently

4. seal with wax

Fantastic "how to" Dave :) 

thank you :) 

Not sure if this tarnishing of the plasti-chrome may be aggravated by the trend to have cars washed cheaply, with no personal effort, by our friends wealding pressure lances loaded with high clean chemicals such as truck cleaners. Known to wreak lacquer.

Kind regards,
