I have marks on interior plastic and I cannot seem to find a cleaner. I tried meguirs interior cleaner and didn't clean

 

Idk if you have any dollar stores around you but see if you can find a household cleaner called "LA totally awesome" its a yellow color, it has to be diluted with water, at least 50% never use it full strength, it works good for me,

 

Mr. Clean magic eraser! haha

 

The only thing that removes interior
Scratches is to remove the parts and
paint them with a interior trim same
Color dye I did my rear hatch area
In black looks perfect.
