I've been doing research for the easiest cosmoline removal technique for a Mosin Nagant 91/30. The general consensous is to soak it in mineral spirits. Naturally, the barrel is extremely long and difficult to find a proper tank for. I have seen people build a standing tank out of PVC pipe with the bottom sealed. Is this the best way? If not is there something else easier? PVC would most likely be the cheapest, at least I am guessing. What have you guys seen? What are your experiences?
