How to remove scratches in textured plastic?

Hello together, I’ve had an ugly scratch since yesterday, which I can’t get rid of with water and microfiber cloth or rub. See picture. (Sorry, it should actually be turned 180 degrees; the picture is on my head). What do you think, how I get the best away? By scratching the spot has already become something more shiny Hope, you can help me? Greetings Buddy
