Yes and we also aggressively attempt to limit it's affects as much as possible. So why on earth would you want or need to use something that has the same corrosive propagating characteristics as what your trying to eliminate? Personally don't care how anyone else cares for their guns. Of course it's a shame when you see a perfectly serviceable gun with a ruined barrel because of improper cleaning. I don't feel any need for some fancy wonder cleaner with peroxide as part of the mix. Though I got to say Stumpy's Moose Juice is pretty darn good stuff for a lot of BP applications. Even use it now for my wiping solution in my BPCR rifles.Ever wonder what role potassium nitrate plays in black powder?
