I used the hot shower method also, but never for cosmoline. A friend of mine worked at "Ordnance" at Ft.Bragg while I was there. I visited him one day and he showed me how they did it in those days. They had a vat with Trichlorethelene(?) that was heated until it became a vapor. He lowered a 50 cal. machine gun barrel, packed full and a heavy coating on the outside, into the vapor with a hoist. Within a very short time he pulled it out and it was cleaned to the point of the pores of the steel had been cleaned. He had to dip it into a vat of oil to keep it from rusting right away. That stuff would pull all the oil out of a stock also, but I don't think it is allowed to be sold anymore due to the danger of cancer. It was impressive though.
