I have had my blackbook for a while now. I have bought a cheap ebay cover that covers the keyboard as well as the palm part and it works good (I think) except it is starting to rip and does place keymarks on my screen. I have some dirt on the bottom of my screen under the plastic and in the hindge I see. I need to find a way to clean it all and keep my keyboard and palm rest clean. I am a college student and on the go all the time so keeping a cloth and such in the middle is kind of hard. But is there any other way of keeping my macbook in nice shape. I do have scratches on the outside but that is a different story. Thanks in advance.
