While at a local gun shop, the man behind the counter told me that 1....if you shoot corrosive ammo through a rifle that it should be cleaned with a water based cleaner, and 2.... if you couldnt clean it right away, you could spray down the bolt face, chamber and barrel with windex and that would take care of the problem till you cleaned the rifle. Has any one ever heard of this? It was a new one for me.
