i noticed that my powerbook stains easily, its not hard to remove but i just want to know what kind of solutions i should use to clean it. i dont want the silver to peel off. do you think a slightly damp paper towel will damage the color in the long run? an ive heard about the hand acid peeling off the silver paint. what can i do to prevent this? use one of those palm pilot screen protectors? what size and model should i get if i decided to buy those screen protectors.
