I would say no after reading this in the description: "It's chemically treated with lemon oil to condition and enhance the beauty of fretboard woods."
Great for rosewood boards, but I personally wouldn't suggest using lemon oil for cleaning a finished neck or maple fingerboard.
I never knew there was lemon oil in the Gorgomyte. But it must be a very small amount. The primary oil is something different that I can't identify. But I would never use any oily product on a finished maple board.
