Scratches on the outside on the rubber on my Inspiron 7352

I happen to have lots of minor scratches on the bottom of my Dell Inspiron 13-7352 Special Edition 2-in-1 laptop. But recently, the top part of the rubber, behind the screen, has this undelighted scratches, that are some what deep and makes the computer look horrible. I did a google search and youtube search, and didn't find a solution for my issue. So what should I do to get rid of these scratches?
