Shower them and wipe them clean from factory dust. Then, oil them [maximum half a teaspoon of oil on a clean shoe-shine sponge, per rack, just for the edges, as barrels. Then, you wipe off any excess oil with a micro-fiber cloth. With the now somewhat oiled soft cloth, oil the faces' perimeter, tryiing to avoid the inlays.]I'm just bothered by how unclean it looks close-up and I don't think oiling is going to help with that. But obviously CPC is the top of the line custom available so I decided to go with it.
CPCs are NOT really a ready-to-use product. With proper care (as above), they can mostly stand up to Paulsons.
