Schipo, just what are these "natural oils" on tonearm parts? A possible lubrication on pivot points I can understand but I am not aware of any natural oil occurring on metal parts themselves.
For anyone concerned with providing a "protective" coating, I would suggest a dedicated automotive or metal polish or wax. Any liquid that does not evaporate away completely, like WD-40, will leave a residue that may attract dust and dirt.
