What about plastic trim with fine scratches rather than discoloured? 2016 RRS 4.4 TDV8 Autobiography Dynamic in Montalcino Red and Stealth Kit

Assuming you mean painted plastic trims
You're best off trying something like 'AutoGlym Super Resin Polish' first to see if they are reduced. SRP has mild cleaners in it aswell as mild filling capabilities. Means the scratches will still be there, but a lot less visible to the eye.

You need to be careful with painted plastic trims. It's not impossible to polish them out, but I'd try the above and see what result you get first. Plastic trims such as 'B' pillars are often very soft, so you need to be careful how you treat them  ON THE WAY: BMW F21 M140i

Mine looks like hairline scratches in some places but two area by hinges are white. New trim is 35.60 and boot button 16 odd so gone the new route but will get a bottle of miricle juice to preserve new trims. Had parts been more expensive, £23 plus vat for C4 might have been the answer. 2x TDV6. SE and HSE. Both returned to sender with issues👀
