Well... after three months of use, my white Pro keyboard is starting to get gunky with eyelashes (I freaking must lose twenty a day... don't know what's up with that), pizza and cookie bits, etc. Especially underneath the plastic just above the arrow controls. Anyway, what's the best way to clean it? I've just been popping keys off to get underneath them... is that bad? And how do I clean under the clear plastic parts?
