Nothing fancy. Indeed, graphite leftover from the Bullseye is a good thing for the operation of the measure. Just operate it empty a few times to dislodge remaining flakes, tapping the side between each throw with a wood dowel or screwdriver handle that won't mar the finish. You can also invert it and tap it to get the hopper clear. One or two flakes of bullseye mixed in with a normal powder charge won't affect pressure enough to matter and their influence will be lost in the noise of normal variance. After the first few throws, any that are left will be gone, anyway.
If the measure is binding at all, that's another matter. You can pull the drum out and wipe it and the drum journal in the casting off. I would rub a little graphite powder into both afterward before reassembly.
