Saving corroded cases?

[Dan97526]

I shot a few rounds of BP 45-70 last month. It was somewhat impromptu, so I didn't have a wash bottle to store them in. To compound matters, I forgot about them until today when I took them out of my truck. They were covered in large spots of a very pretty blue-green corrosion. I've ran them through the dishwasher but some corrosion remained. I'm tumbling them right now in walnut shell to take off the rest. Even assuming they come out clean, should I discard them?

Thanks,
Dan

I wouldn't toss them. If they aren't pitted, I suspect they are just fine.

They will clean up in a tumbler.

I load the Gypsy wagon in the middle of May with around 2000 rounds loaded for a couple rifles going to several different shoots. I put them in a bucket with a lid to keep as much moisture off the fired cases and I get back home around the later part of July or August and throw them in the tumbler to get them clean. They come out looking like new.
