I think it is not possible to remove or improve such scurfiness, just to preserve it the material. I use natural beeswax, but again very slightly (small quantity). I also (but I do not know, if it is good, or wrong) use hair drier (carefully, from bigger distance to heat only the wax - e.g. old wooden handle could crack) to dissolve the wax on the surface and then I polishe it with soft cloth
