Depending what kind of tools you use, I use spray on Turtle wax car wax. I did that when I did telephone and data work. In those cases your tools may get wet but you do not want to leave oily fingerprints on peoples walls, cabiness and furniture. Most of my ammo reloading tools, dies and equipment is raw steel. I spray the stuff down with car wax every so often. It heeps everything from getting that rusty coating and there is no oil to contamninate anything. Good Luck
