I can not for the life of me figure out how these got there because its not like I use anything other than my fingers to press the buttons but the face and screen on the front of my radio has all these tiny scratches. Probably nothing I can do to fix this right?

 

The plastic is soft enough to be scratched by the dirt you don't notice is on your fingertips. The way to fix it is: stop caring about it, or constantly polish it. Because radios get scratches.
