Today I walked into a small gun shop to check his prices on brass (I'm about to start reloading). His shop was packed with ice cream containers full of disassembled pistols and trigger assemblies soaking in two-stroke fuel. He swore that it was all he used for his gun care. The petrol cleans and the oil lubes. While I'm not going to start doing it myself, to be honest I can't see in his fallacies in his logic. Any thoughts?
