I dont really care about the history of corrosive salts including that cropped up in the 1920's ???. I know for a fact if you rinse the chamber and barrel with water and clean with hoppe's you will remove the corrosive salts and not have to worry about rust. Water removes the salts and hoppe's takes care of the ''oils''. I never said water alone was the magical solution but water and good ole hoppes #9 seems to be. Could be the chlorine in the water aiding in the salt removal. Its been working for me and my three mosin's for over 10yrs. Dont know jack about chemistry, just what works on corrosive ammo in my rifles.
