rickC- Yes, I have used this mix for about five years. The hydrogen peroxide costs about a buck a pint, the 70% rubbing alcohol 48 cents, and Murphy Oil Soap maybe $3.50 a quart. Mix in thirds and keep in a dark bottle. Very little needed and those volumes will be enough for years of shooting. Also, the Murphy Oil Soap is made for cleaning wood, so I use the mix to clean the blackened parts of the stock. You can even use it for a patch lube. A friend, Lynn, uses it in her little left handed custom .40 flintlock built by her husband, Neill Fields, with a .375 pistol ball and Ox-Yoke patching. She won the last high-dollar blanket shoot here (entry prize worth at least $100, about 15 shooters). I have never had any after-rust, and sometimes wait till next morning to oil the bore, just to see if it will rust. Very low humidity here, or I would oil it right away. And I also stand the muzzle down to drain any exess away from the flash hole or powder drum. For patch lube, I use half Murphy Oil Soap and half 91 % isopropyl alcohol (less water against the powder). Either pre-wet and keep in a cap can, or use a squeeze bottle at the bench. Can shoot as much as I want with no wiping or cleaning. See my post in Flintlock 8/01/05, "Swiss and Goex 2F and 3F compared". You can also use straight Murphy Oil Soap as a patch lube, it is almost a grease. I have not yet shot a long string with that, so don't know how well it works.
