Oxidation or black speckles on MBP casing

[spookje]

Since some days black speckles appear on my MacBook Pro from begin December. Does anyone know if this normal ? I have scratches that's not a biggy but those black speckles are really annoying and aren't scratch like. Its near the fn function key and below the speaker.

This was fairly common on the Aluminum PowerBooks. I got this myself on a 12".

It has to do with having a certain chemical makeup in your skin's natural secretions, and not cleaning your laptop often enough.

Since it's still under warranty, I'd try for a repair. They can replace the upper casing. They may consider it "wear and tear" or something, but Apple has repaired this issue before. You just need to get the right rep.
