Sanding down the neck is easy and imho very worth it.
Dying a fingerboard however sounds like a mess waiting to happen to me. Cant you oil it to make it look darker? Think about the sweat and dirt the dye would have to put up with.
Don't use steel wool. Unless you feel like getting tiny steel shavings attracted to the pickups (it will happen, no matter how hard you try to prevent it). You do not want those steel wool shavings anywhere near the coils, as the shavings rust, which can become sharp enough to sever a coil wire and end up killing a pickup. Just use sandpaper or a scotch-brite pad.

kramersteen, nice looking stain job on those boards. How did you get the fret markers so clean afterward?
So you coated the board with the citrus oil first, then stained it?
Did you seal it afterwards? Like with a tung oil? Or a sanding sealer? Or just wipe the stain and let it dry?
