Hey guys I just sold my 2010 MBP and decided to get a used 2016 macbook 12 inch with retina. I am absolutely loving this little computer but I noticed when I was cleaning it last night that I could see some small imprints of the keys on the keyboard and I tried cleaning the screen off and it almost seems that it is permanent? Does anyone know what to do to get these removed or does apple have anything to say about it?
