oxidation / verdigris

I found some 70 year old stuff gone bad in an ammo can, about 300 rounds of 147 grain FMC, lead filled. I was able to save the bullets at least with a 5 min CLR soak. Their website does NOT recommend it with brass or copper. I've never used it before but based on a recommendation...picture shows the results.

Evaporust would probably also work. I have used it to soak brass parts, it will tone the metal, but remove the crud. Looks like the bullets came out all right.

Thanks for that tip. I had never heard of it, and I see it is a little easier to use, not as caustic. I have a bunch of hand tools the kids left outside I'm going to try it on.
