I've had this issue with both my black macbook and my aluminum macbook pro. Over a couple weeks, black junk gathers up on the bottom right edge of my mac. It's on the front side to the right of my trackpad, where I normally rest my hand while using the trackpad.

Just wondering if anyone else has this issue, what it is, and how to stop it from happening? :confused:

Thanks

It's tarnishing due to acid from you hand's sweat and unavoidable. If it happens fast Apple usually replaces the entire casing for you.

Mine started getting tarnished about a week or so after I bought my MBP (2 years ago) and I promptly complainted to Apple.

They replaced my case no questions asked, and it's been 2 years. The tarnishing has come back slightly but they must've added something new.

For me, diligent wiping with wet cloth has been able to prevent any stains.
