I think my Aluminium keyboard is TARNISHING!?

[fluidedge]

could this be possible? The keyboard is starting to get a sort of dirty oxidation above the arrow keys (no - it's not just dirt)

how can i clean the keyboard?

Apple aluminum keyboards are made from anodized aluminum, which does not tarnish. You can clean it using a damp cloth. Just take out the batteries (if wireless) or unplug it from your Mac and use a damp cloth to rub the area. Be careful the cloth isn't so wet that it drips water inside, or so coarse that it scratches.
