MacBook Pro :: Ways To Keep Keys Clean?

I currently use a keyboard protector (Moshi clearguard) on my MBP but after usage, the protector makes the keyboard really ugly to look at. It isn't as "clear" as many people have reviewed. Anyway, when I try using it without the protector, the oil from my fingertips (my fingers feel dry!) seem to make the keys glossy (the nasty kind of glossy)

I realize that I can use the keyboard without the protector, and then scrub it down every week but that seems like a huge hassle.

Is there a way I can make the keys look exactly like they look without the protector and still make it resistant from the gloss from the skin oil?

Maybe apply a small special film on each of the keys? or get some professional coating done on the keys?

The Moshi protector seemed somewhat clear when I first used it but after time, it really isn't clear and makes the keyboard look dirty
