Removes Rust Easy From Your Gun.
How it works: Frontier Metal Cleaner looks a lot like a steel scrubbing sponge made up of thin coiled ribbons of metal. The coils are composed of a proprietary alloy containing stainless steel, nickel silver, monel (a corrosion resistant nickel based alloy), and zinc. The alloy is effectively “harder than rust but softer than bluing.” As a result it can be used to scrape the rust, dirt, and dried greases and oils off blued steel without harming the finish.
 
Moreover, Frontier Metal Cleaner is significantly more effective than other “sponge”
cleaners, like bronze wool due to the shape of the individual strands. Since each strand of Big 45 Frontier Metal Cleaner is a thin, ribbon of metal with sharp leading and trailing edges, it has the effect of hundreds, if not thousands of small razor blades scraping away at surface build up. Steel or bronze wool, which is round in cross section does not have this advantage.
