The Hungarian is definitely corrosive and that's all I've fired from my SVT40. The best and easiest way to clean the SVT is to strip it down (not that hard really once you've done it a couple times), and foam it with the foaming gun cleaner. No scrubbing of small parts. Foam, leave for a while, then wipe off foam. Foam on foam off. The foam gets into the nooks and crannies and neutralizes the salts.
I bought my SVT from a member of this board and recieved it with the gas system rusted solid! Once I cleaned and fixed it, I've used nothing but the foaming cleaner with no additional rust since.
