As a collector of old reloading tools, I purchased my first Ideal #310 reloading tool and dies as a set from our favorite auction site to reload 30-06 cartridges. The tool apparently hasn't been used in a long time, and suffers from some rust spots and slightly damaged threaded pieces. How should I go about cleaning this tool and dies? Are the threads common so that I can use a thread file to straighten them? Should I use a brass wire brush or is a steel one ok? How about chemicals and/or lubricants to protect the cleaned tools?
