Cleaning titanium cylinders on guns like 329 pd and 342ti guns

M Pro 7 gun cleaner and a nylon brush. Give it a couple of squirts and let it sit a while then hit it with some elbow grease. Lead wipe away cloths are not good for the coating and stay away from any kind of wire brush.
 
I recently sent a 929 back to S&W for a broken trigger pin repair. Thousands of rounds thru the 929 and I just live with a black cylinder.
When it came back after the repair, the cylinder looked brand new. Not sure how the factory cleans them, but it looked new.
And it was my original cylinder, because I can see my chamfer on the cylinder.
 
My guess is the factory uses an ultrasonic bath…… but just guessing on that.
 
Never look new again

Don't try to make it look like new. Hopes elite or Mpro7 and nylon brush. Done. You have the ultimate lightweight revolver, not a heirloom show piece.
 
Has anyone tried ultrasonic cleaning? I wouldn't think it would damage the cylinder.

You have to be careful about what solution you use. Some of them can damage the coating and pit the metal. Stick to a solution that can be used on aviation parts.

I've yet to see Hoppe's #9 hurt anything. Why not use it?
