The Dreaded Brown Stains...

I've got the dreaded staining on the sides of the touchpad and the touchpad and pad button. I've been using Mr. Clean's Magic Erase and it's doing a decent job but not removing 100% of it. I do wash my hands a lot but evidently this isn't a cleanliness thing. I've had the laptop since last July and while I don't use the laptop overly much (I've 8 other machines in the house, not including my wife's laptop), I use it just enough to where it should be getting a bit of wear on it in 7 months of use, so I'm not going to report it to Apple just yet, unless it gets a lot worse.
