make sure you get all the old cob media out of your tumbler before switching to wet tumbling... looks like soggy grape nuts in my cases & in the pins... I think I had static on my drum, & not all the cob media would come out easily... add that I wanted to get pre washing my pins... figured I'd just rinse them out... that ain't happening... looks like it'll be many tumbling sessions before I get the last of them out of the system
