I figured this must be a late April Fool's joke.
Take it from a boy from down on the Gulf; you'd be dumb wash off a hammer in salt water, no matter how oily it is.
I've done it numerous times. Never any issues just make sure it completely dries before holstering in a leather holster. It would behove you to use fresh, incoming water on the incoming tide ( not Brackish ) for the thorough cleaning as it removes all acids and oils. I would not hesitate to try this with any of my revolvers as salt does clean away any plastic chemicals. A must try for anyone with a metal frame and great wood treatment that needs cleaning.
Good Luck and be safe
A blued revolver? UHHHH, No. A Glock? Heck, go ahead, it's already ugly and will probably outlive us all. Chuck Taylor is presently proving it with a G17.
For these who live too far from the Gulf, try this.
Tie a string to the trigger guard, drop in the toilet and flush once for every 50 rounds since last cleaning. Then hang on clothes line till dry.
