What you should use depends if it's nitro or poly (Warmoth has sometimes used nitro for satin finishes but not gloss, so check carefully), but otherwise it's the same as cleaning a guitar body finished with the same material. Some guitar finish polishes are all-purpose and will clean up both nitro and poly, but check what you have carefully as most cleaners and polishes are made for one or the other.
Basic cleaning alcohols, or even lighter fluid, can clean poly finishes. Don't use either on nitro, as though some very thick nitro finishes can appear unscathed, the top coats will be damaged and thin finishes can end up getting stripped if you're not careful. Just not worth the risk when actual nitro cleaners and polishes exist.
Cleaning oils do not belong anywhere near a finished maple fretboard. All they'll do is sit on the surface of the finish at best, or stain it at worst. Oils are for raw wood only, and even then are for conditioning, not cleaning. Over-oiling a rosewood or ebony neck (or any other raw wood) can lead to severe problems. Don't break out the oils more than once a year, no matter what raw neck you have; for finished maple, keep the oils locked away.
