Isoprop as a preferable first resort, as others have suggested.

If that doesn't do it, common TSP (Tri-Sodium Phosphate) is good at cleaning off grimy organics.
However, best to be taking things apart so keycaps and housings (not the electronics or keyswitches) can be immersed in solution and then thoroughly rinsed.
I wouldn't want to let TSP soak into parts from a wipe-down where it couldn't be well-cleaned-out.
