Hi, ever since I got myself a Unibody Macbook I was worried the keyboard getting dirty so I bought this Moshi Keyboard Guard. I have been using it for about 3 months now and I am so glade I bought it!! The keyboard still looks awesome and all but the Keyboard Cover is turning into a dirty looking plastic... I know the website says it is washable in water but I need some specific instructions since I can't trust myself xD I might go too far with it! Thanks in advance ! Have a great day!
