I did a great deal of experimenting with what worked and how well when Blackhorn came out. My conclusion was that nothing else worked as good as alcohol but I have experienced flash rust with it alone so I mix #9 with it anything from a 50/50 mix to a 80 /20 mix will allow the alcohol to do the job and the light oil distillate in the #9 will prevent problems with flash rust. If you oil right away its fine to use 90% but I don't put oil in my barrels when I am going to hunt.
