Cleaning raw wood on stock?

[Fatelvis]

I just bought a near unfired/excellent+ enfield, but the stock is a little "dirty". It looks like someone with dirty hands handled it a few times, and the dirt got imbedded into the stock. (The stock has very little, if any oil, or other finished applied. Looks almost like raw wood). How can I clean it off, without disturbing the cartouches, raising its grain, etc? Thanks guys-

Try mineral spirits on a lint free cloth.
