I have a 13" Black MacBook and am having some problems with smudges on my LCD. I regret getting the black color because every little smudge shows up on the body of the laptop. I keep it very clean by frequently wiping off these marks with a microfiber towel. I do the same with my screen to remove fingerprints and such, but I've noticed something. Whenever I close and then reopen the MacBook, there are smudges in the outline of my keyboard. Is there anyway to help prevent this? It's very distracting when I'm in a well-lit room and these smudges are very visible.
