For initial cleaning I usually use corn cob and it does well. My process is lube, “prep” (decamp, size/trim, etc), then tumble the lube off for 30m or so, then load whenever.

My issue is that I’ve had some bits of corn cob cling to lube inside some cases and turn into “rocks” in there.

Does anyone have any better ways to tumble the lube off that might be more complete. I didn’t have issue for a long time then it just started and it seemed like it was dustier than before too. Maybe it was that run of media idk.

I’m open to most things but probably not wet cleaning given time and expense.

Thanks!!
