1. A method for processing polycrystalline diamond (PCD), comprising:
placing the PCD in a vessel, wherein the vessel is an enclosed system, and wherein the PCD comprises a PCD layer and a substrate;
applying a first fluid to the PCD in the vessel, wherein applying the first fluid comprises immersing the PCD in the first fluid such that all exposed surfaces of the PCD layer are covered by the first fluid; and
applying a second fluid to the PCD in the vessel, without moving the PCD from the vessel, wherein applying the second fluid comprises immersing the PCD in the second fluid such that the PCD layer is exposed to the second fluid; and
agitating the first fluid or the second fluid by moving the PCD within the first fluid or the second fluid.
