Corrosion On Cartridges

[troutchaser]

I have two bricks of .22 lr ammo that needs some attention. The cartridges have never been wet, but they were stored in a basement for several months. I pulled them out to use them the other day, and they all have a ring of scaly corrosion where the bullet meets the case. It doesn't look too thick, but it's enough to prevent them from chambering in my Marlin 60 semi-auto.

Are there any techniques you could recommend to remove this junk safely and easily?
