Do you clean brass that’s just been on the bench?

Question for you people much smarter than me. Lately I’ve been doing more loading and testing with small batches of brass and I’ve come up with a question. Do you guys feel the need to tumble (wet or dry) brass that was loaded, shot, ejected from a bolt gun onto the table, then picked up and tossed in a baggy? I do a wipe down but I haven’t been tumbling. Am I missing out by not tumbling and getting the insides clean or is tumbling mostly for range pickup that’s fell into the dirt/rocks etc?
 
No. I tumble brass after FL sizing only. I usually anneal, FL size, tumble. Next two loadings I only neck size so my brass only gets cleaned every third firing to clean off lube. I don’t care about shiny brass.
 
Need to? No. I choose to because it adds no time to my process and I like clean brass in my sizing die and I like the look of bright shiny brass. 😄
 
I will clean after a few firings but generally I just wipe them down and run a nylon brush chucked in a drill through the neck. It takes any crud out and leaves a nice burnished finish for seating bullets. From there I resize and load ammo.
 
I don't clean beyond wiping off obvious dirt. Even if it is covered in myst, I just rinse it off and let it dry.

I will use a little acetone to clean lub off after resizing.

So, my vote is no.
 
I tumble in corncob media after sizing to get the lube off. You don't have to clean brass as long as it's not filthy.
 
I tumble clean in walnut media after sizing long enough to get the die wax off. They still look nasty and I don't care. They shoot.
 
When loading at the range sometimes I wipe the necks with never-dull to take the carbon off. A twist or two is all.
 
Got a Lyman tumbler and 5# of walnut media so might as well use it. I have a simple wall timer so I just put ~150 in at a time and let it run for 2hrs in the garage. Whenever I get back to it, I dump it out. Total effort (including dumping out media from cases) ~10 min. Makes me feel good and they look purdy.

The more I hear about people getting cold welds on handloads makes me wonder if I'm better off leaving as much carbon in the neck as possible though... adding in a dry lube dip to put something back on after tumbling to get it off just seems silly.
 
I tumble to clean lube off also, it is nice to have shiny cartridges loaded up. Not necessary though.
 
I barely get around to cleaning brass that NEEDS cleaned. WTF would I clean brass that is already clean?!
To be fair I like to stand around in my shop and drink as much as the next guy but cleaning brass that doesn't need it? That is like ice fishing - I don't need to drink bad enough to do THAT...
 
I just want to say that I did something the other night that I rarely do - most of my reloading is dirty brass or brass that comes packed in nice 50-round boxes. I dipped into a 50-piece bag of new Starline brass.

Shiny, new brass cases, with the perfect amount of lubricant on them, for me to run my fingers through to grab 2-3 at a time and prime, then lay out in a loading block, then I charged them all with a measure (I usually weigh charges) and seated them all.

Something about the clean brass in a bag was soothing. I may clean some brass and offer to let people come process/load it for me for a nominal fee as stress relief. Like Tom Sawyer's fence.
