Advice needed - remove scuffs on plastic

I have one on my armrest in the polo, a bit deeper than your ones but very thin, It catches my eye all the time. There is no way of getting rid of it and probably will make it look even worse if you try. Yours dont look as deep as my armrest one. Try giving it a good clean with a strong APC solution and then use a dressing on top like mentioned, it wont get rid of them, but I reckon it will do a good job on yours to atleast make it look better. Nothing to lose is there ?

As above nothing you can do due to the textured surface plastic.

If it’s a light scratch on hard plastics you could try a heat gun or hair dryer. It will soften the plastic but mainly get the oils or something out the plastic so it’s less noticeable as the colour evens out. After that a dressing like carpro Perl which is my go to dressing for pretty much everything.
I’ve tried this years ago on an old car with a scuffed faded bumper and it worked quite well.
