Best cleaning and lubrication for weapons using corrosive ammo? I've an AK74 with which I use surplus russian ammo which has corossive primers. Right now I pour a tea-kettle full of boiling water through the receiver/barrel/gas tube, then clean with Hoppes, and lube with a few drops of Dexron VI. This seems to work - no visible rust. Are there any other better/different/easier ways of cleaning corossive residue?
