I'm not sure if there's something I can do at home, and given that my 2010 27" iMac is a beast I wanted to share here before I lug this thing to the store.
I've included a picture of what I'm talking about. You can't really see it unless you have a white background. At first I thought it was dirt and tried to wipe it away, which didn't help.
