cleaning corrosion off old ammo?

[Mule]

I have a bunch of 30-06 on belts and want to run them through my 1919a4. Problem is, when I opened the cases up the brass has corrosion on them. Do you guys have any ideas on how to clean them off? I don't see any major pitting yet....
I was thinking some ammonia and washing soda in a spray bottle might do it.

Based on your description of the extent of the corrosion, I would not use ammonia or liquids. I would use fine steel wool.

Steel wool on the heavy spots, then just put 'em in a tumbler with dry walnut media, get Kaytee Bird Litter from PetSmart. You'll have to de-belt them though.
