I like Clenzoil for the same reasons Gene Batchelar does. I use it mostly for lubrication and long-term storage. For cleaning, I prefer Ballistol. Ballistol is even less toxic than Clenzoil and it cleans at least as well. Like Clenzoil, Ballistol is harmless to wood finishes, In fact, Ballistol works well as a wood polish. Ballistol also does a good job on cleaning and preserving leather...along with a whole lot of other applications. (See the Ballistol website. Unbelievable!)
Ballistol works well as a black powder/corrosive priming cleaner, too, mixed with various proportions of water. As a frugal (e-wives; CHEAP)type I like to spray a 10-to-one mixture of water to Ballistol mixture down my barrels, followed by brushing, as a first stage of bore cleaning. It is amazing the amount of "crud" that comes out. I then follow up with Ballistol, full strength. (Interestingly, a 10-to-one will still protect agains rust.)
