I would tumble them for a few hours in walnut media.

It all depends on the condition of the cases under the verdigris.

If the cartridges are fairly clean otherwise, tumbling and give them a different appearance than you want.

I soak such cartridges in DIESEL FUEL for a few days and the green waxy residue wipes of easily with paper towels. The thing is, where the verdigris adheres, the brass directly underneath will be quite bright, with a green tint around the edges.

Cartridge cases are extruded and show it. Tumbling lightly as mentioned might even out the stains or it might not.
