Help salvaging a cartridge

Is this cartridge worth spending any more time on it? It was completely covered in the liquid blue corrosive goo.

Normally I wouldn’t bother, but it’s the factory pressure test round with an AP projectile.


Nah, not worth your time. PM and I’ll give you an address to send it to for safe and timely disposure ;)

Everything is worth saving imho, especially something like this…

Even if you “hurt the value” of it while cleaning, at least you’re cleaning it and preserving it instead of just letting it die, that’s just my view anyway.

I have tried a soak in oil and then a brass wool rub to remove the corrosion, then wipe clean with a paper towl. If the oil should slow down any corrosion. I am sure there are better processes but this is quick and easy and seems to work pretty well.
