Hi all. Just moved, and I opened the trunk where I had carefully packed all of my reloading equipment to find that just about anything that was metal had rusted to some degree. My old RCBS manual brass trimmer was frozen so bad I couldn't turn the handle, to give you an idea. Most of my dies had rust on them and inside them, a few of them pretty bad. I used muriatic acid to clean off the trimmer as a test, because I'd heard it takes off rust. It does, very well, though it's caustic and hard to work with, bad fumes, etc. I cleaned it up pretty quickly though and had it back to serviceable in about 5-10 minutes. The acid also takes off any finish, so I oiled it well with Kroil. Okay, so I want to try this with some of my dies, the ones I think I can save anyway. At least one is so bad that I'll just replace it. Any reason why this would be a bad idea? I know that on some level the die dimensions will be different, but I don't think it will be to a dangerous degree. Opinions? BTW, this happened simply because I wanted to save a $5 bottle of Scent Killer detergent, and I put it in the trunk because it was convenient at the time. My Hornady 50 BMG powder measure is toast, and maybe one of my bmg dies also. I think I can clean the presses up, we'll see. Hope you all think more than I do before you do things!
