depends on your finish, but i woulden't recommend using steel wool on a maple fingerboard because mostly it's a finished fingerboard and steel wool would ruin the lacquer

Suggestion: a Sticky on MM neck cleaning.
Hi Dany,
If you receive search links and such (the one posted didn't open for me), it's because this is so often addressed on this forum. It's a rather lengthy thing to go into because there are variables and personal preferences of procedures. There's no one absolute way it must be done.
My suggestion is to first try the search function, with key words: Birchwood Casey, Murphy's Soap, cleaning necks, neck care, etc. I'll check back later if you haven't found what you need, unless someone else gets to it first.
