I recently picked up the unibody Macbook Pro. Being a fool mixed with wanting to show off the gorgeous nakedness of the machine - resulted in me bypassing any thoughts of a sleeve for this sleek computer. Since then, I have a small soup stain just to the left outside of the trackpad which seems to be a hardened water stain - which can be seen and felt. Also, I've noticed its quite easy to acquire grease marks on the black keys. Are there any techniques I can use to clean stains off of the brushed aluminum body? As well as the keys and monitor without damaging them? I plan on getting a sleeve to help prevent anymore imperfections.
