Yeah, actually. I have a wired and wireless apple keyboard, and you can pop all the keys out, soak them in dish detergent or something to get gunk out of those, and use various tools such as q-tips and such to clean the bottom part out. Quite efficient, in my experience. Just be sure to pop the shift and spacebar keys back with the metal in the right place. Not too complicated. I think there's a few other keys with metal wire in them too, same thing. I imagine any other keyboards are similar.
