Can't be too clean...
After many years of doing it each way,I now tumble clean,lube and resize/deprime,rinse in hot water to get rid of most of the lube,air dry,then tumble again.
After tumbling,I inspect each case and pick grit out of the flash hole if necessary.
I use walnut impregnated with red jewellers rouge.I don't want to kill it off prematurely by tumbling lubed cases in it,though it will do it.
Sounds tedious,and it is,but I end up with sparkly finished ammo.It leaves a bit of the jewellers rouge residue behind in and on the final finish,but I don't see that as a problem.My brass ends up very bright.
I disassemble and clean my dies periodically too.
