delinked ammo
I recently got a few boxes of 308 that was removed from links . half the rounds look real nice some have some white corosin on them ."not too bad" they are brass case . I am tempted to clean them up by hand or maby spray them with something to stop the corosin . I have enough that I will have them for years before they are all gone .ANYONE have any ideas or advice THANKS in advance .

The ones with the white corrosion is actually a deposit left by the links they were in. My guess was they were likely in M-60 links which can leave a deposit on the brass.
Dont spray them, you might foul out the primers if they are not sealed.
The best way to clean them is to put them in a vibrating tumbler with dry media for 2-3 hours. That should clean them right up.

I agree agree with the tumbler. Use treated corncob media, let it run for a couple of hours, and you'll have nice shiney new looking rounds.
I know this won't work for corrosion, but thought I'd mention it incase it helps, but alot of the .303brit ammo I get has this green goo on it thats a real pain in the rear, really makes extraction and chambering harder in my bolt rifle, so I just fold some papertowels, spray the paper towels with some MPro-7 cleaner, then put the cartridges on the moist paper towels and roll them around on it, then I take a nice dry paper towel and rub the remains right off. Works really good.
If I'm wrong please correct me, I won't be offended.

I'm sure if you used some Break Free CLP instead of MPRo-7, it would work really well.
Just an idea incase you don't own a tumbler.

WHOA!!
I could not disagree more strongly with some of the advice you received above. Under no circumstances should a tumbler be used for loaded ammo, especially military rounds with (relatively) sharp pointed FMJ bullets. The manufacturers, the NRA and common sense all argue against it. Unlikely, but under the proper (wrong) conditions, the point could hit a primer hard enough to ignite it.
With a vibrating bowl device, this is far less likely, but I still advocate against this practice although I know there are those who will argue with me on it (we've had this discussion before ). It is my belief based on observation and anecdotal evidence that tumbling loaded ammo can result in fractured powder grains, abrasion to the retardent coatings on the grains, etc., resulting in altered pressure curves and, potentially, a KB.
This is not collector ammo. All you want to do is remove enough of this residue to allow the ammo to chamber and extract reliably. There are any number of household products, to say nothing of specialty chemicals, which will do this quickly and reliably. Under no circumstances use any product designed to penetrate (e.g. WD-40) or leave a lubricating film on the case; on those road lie misfires and worse problems.
Now in one place you say "a few boxes" and later the supply will last you for "years." So it's not clear the volume we're talking here. But a white residue is from the links as Laredo noted, not the brass. It won't get worse. You can clean as you have time or you can do it all at once. If you reload, once these have been fired you can do all the chemical / mechanical cleaning you want, until they look like factory new, if you wish.0 -
I've used the case spinner from a Lee trim set and steel wool to remove tarnish and corrosion from cases. Kind of slow but lots safer than the tumbler idea.

After reloading for 60 years, would NOT tumble the loaded cartridges.
What Iconclast said sums it up in a nutshell. Breaking the powder down into smaller pieces will change the burning rate. Just like
using FFFG black powder in a large capacity rifle shell that calls
for FFG black powder. Just hand clean it to fit the chamber and shoot it. If corrosion is much, dont use it for reloads. Dont spray it.0 -
I used to be on that school of though, partially still am, and common sense would say not to, however after some serious thought and testing, I've found that when a rimfire case ignites in your tumbler, it really doesn't do much but make a little pop noise. And I've yet to get a centerfire cartridge to ignite.
When a cartridge ignites and does not have a chamber to support it, it just pops like a firecracker, the brass spilts, and sometimes the bullet doesn't even fall out.
Now I could be totally stupid and just really lucky, which I wouldn't disagree with you if you said so, but that just from my experience.
If I'm wrong please correct me, I won't be offended.

If you tumbled powder for hours, you might change the grain size, and hence the burn rate. But that would take a long time. I have tumbled live rounds and never had a boom, fart, or fizzle. I do not use a vibrating tumbler, and all the rounds come out nice and clean in about 15 minutes.

Visit an ammo manufacturer and you will lose all fear of tumbling/vibrating loaded ammo. If you were to tumble/vibrate for MANY MANY hours, you could change powder characteristics but not very likely.
