I was just reading a 1976 National Rifleman mag, April issue I think, and a one page article caught my eye. To digress, I was just looking for some solvent that would not be toxic to me (as Hoppes is) not damage a gun. I found G96 but on another forum a person said he had used G96 on a nickel plated gun and it had dulled the finish irreparably. So, this article was carefully read by me and revealed the following: The author recommended using waterless handcleaner, he did not outrightly say the name but the tagline talked about de-Gooping a gun. I know Goop is a prominent brand of this stuff. Anyway, author simply said that guns should be periodically completely disassembled and cleaned. He said use the cleaner and an old toothbrush to clean the parts. It was emphasized that it will remove the lubricant so make sure and relube the gun when finished. I for one am happy to find this article because regular gun solvents have been extremely unpleasant for me to use, even in well ventilated spaces.
