How the hell do you clean the top case ( shell ) of a white macbook without scratching it. Mine had finger prints on it and general dust after just a week and i got the cloth apple gave me and slighty wet it and gently wiped it down and it left scratches. Also when the time comes whats the best product for cleaning the palm rest ? Magic eraser and all the other products i saw people talk about are not available in my country. How about good oul soap and water ?
