Does it work better if you shoot corrosive? I have been shooting a bit of corrosive lately in my AK 74 and so far have not seen any rust. I have been cleaning with soap and water then blowing compressed air and setting it by the heater. I then apply Hoppe's oil.Love it, stopped using RemOil and Hoppe's years ago in favor of using Ballistol, it works great. Especially if you've got Black Power guns or shoot corrosive ammo in your military guns. I've not used anything else for about 10 years now.
