Scuff marks on fender flares

Hello, I have an Off-road 2018 Taco and I noticed that I have some scuff marks on one of my rear fender flares. I believe these are made from a hard rubber-plastic. Just wondering if anyone knows how to minimize these marks?
Thanks

 

I had a similar thread to this yesterday or the day before; these things (the black plastic bits on the fenders and front bumper) collect scratches and damage like nothing I've ever owned. Best advice I saw was using a polisher to try and get stuff out (like Meguiar's Ultimate or Scratch X) and also using some manner of protectant like 303.

I may bite the bullet and just order spares, but it doesn't make much sense to swap them when the truck is so new because they'll just collect scratches over time.

 

Same goes for the inside plastics, and i can't believe how much dust this vehicles can attract!...

 

I noticed the interior black plastic quality about 57 miles in; it was not a great experience. I also don't advise looking at the clear plastic on the gauges when you're in the direct sunlight!!
