I made a huge mistake. I put some corrosive ammo in my safe without even thinking about it. Now after a few months some of my guns, ammo, and magazines have rusted. The guns only have rust (pits) on the outside of the barrels but some of the ammo looks pretty sad. Brass is green and some of the slugs have whitish powder on them. Is there a way to clean the barrels and bullets that won't take forever? Also there were what looked like large rust crystals on a couple of the magazines. When I took some of the boxes of ammo out, the box felt like it was slightly damp. Any advise would be appreciated. A couple of the guns were my Dads' before he passed and it makes me sick to see them.
