MacBook Pro :: How Do You Combat The Oils Of Keyboard/trackpad Doom?

Anyone who knows anyone from anywhere is aware of the fact that finger oils + laptops = eventual doom. Lets face it, an oily keyboard or trackpad is disgusting and makes you not ever want to touch the computer. Also, it makes potential buyers of the system you are selling think twice before buying from you.

I wash my hands and do all the basic hygiene stuff, but its an undeniable fact that eventually finger oil (or face oil depending on how you use your computer I guess) will get on your stuff. For my Macbook Pro (early 2008) I use a iSkin keyboard cover, so the keyboard looks brand new. The downside to the cover is that it touches the screen when the laptop is shut so those oils translate to the display and it needs to be cleaned quite a bit, but thats easy. The trackpad is getting a little slick feeling, which is a bummer because from what I understand, this is irreversible.

On my Macbook Air I use the Moshi keyboard cover which is nice because of how thin it is but cumbersome at times. I have nothing on the trackpad and am dreading the day that new trackpad feel goes away.

So how do you fellow MacRumorites combat the oils?
