I don't see how that is any more thorough than doing it in a wash basin with warm water. I understand he will be shooting it again soon so he doesn't clean and dry the internals, which from the way he cleans it, must be soaked. and rusting He could have soaked it with WD-40 and blown it out with high pressure air, that might have made me rest easier, HAH!. Did I miss something? I don't take them completely apart if I going to shoot them again soon, but with a basin of water I have more control of where exactly the moisture goes.
Its a pretty cool idea, but unless I missed something, not for me.
