Good Morning-
First time rust blueing a shotgun barrel (VH), and I have immediately run into a problem.
I boiled this barrel in a solution of Simple Green and water. My heating set up has an issue, so I did not get to a full boil, but more of a simmer. I am hanging the barrel by a wire and a couple of wooden dowels in the tank, since I will hone the inside of the barrels after I am done.
When I pulled the barrels from the tank and dried them, I see streaking on the lower barrel. It appears to be oil leaking from under the rib?

These stains do not wipe off.
I'd appreciate your thoughts and suggestions!
