Dry tumbling and media care

[kcb38]

My go to process to clean brass has been to dry tumbling w/ a course walnut w/ no polish. Resize/deprime. Trim. Lyman case prep tool, then finalize with a corn cob with NuFinish.

I am just getting set up to reload and this is the process that I have settled on, but I have a couple questions. If the purpose of tumbling after sizing is to remove case lube, would adding NuFinish hinder that process at all? I plan on using the RCBS lube that came with my Rockchucker Supreme kit until it runs out and then I figured I'd switch to lanolin and alcohol. Since lanolin is not water soluble, would it be best to use more mineral spirits for that step? Would a mix of mineral spirits and polish be better? Or could I just use the polish and still get shiny clean de-lubed brass? TIA

For initial cleaning and lube removal I use a dry walnut media. I personally use Hornady One Shot so I can't advice on a lanolin mixture that would work best. I only add NuFinish to my corn cob media which I only use after all processing is completed and/or when tumbling loaded rounds to remove any oil/grease from the loading process. Hope that helps to some degree
