CorrosionX products (USA) are used by the US military and a list of well-known international companies, one being NASA. Consequently, Magnum welcomed the opportunity to test two of their products, CorrosionX For Guns (a penetrant and lubricant) and Rust Remover.
The company claims that CorrosionX For Guns is a “super lubricant and penetrant” that lubricates under heavy loads and high temperatures. It is ideal for fishing reels and guns and is a superior penetrating agent – corroded or rusted nuts, bolts or fittings can usually be removed within a few minutes after application. It does not attract dust, and it outperforms lubricants fortified with Teflon* (PTFE). Due to its unique polar bonding technology, CorrosionX repels water and doesn’t dissipate quickly or wash off in harsh saltwater environments. Allegedly the penetrant will also cut through rifled bore deposits for easier and more thorough cleaning.
To me, an important factor is their claim that it’s not harmful to the environment, is nontoxic, non-carcinogenic and the volatile organic content is only 8.6%. The aerosol products distributed locally also contain a non-flammable propellant.
I began my test by using the pen- etrant on a stuck bolt on my Hilux. I sprayed the bolt and left it for about 10 minutes, then unscrewed the bolt. I then sprayed it on a windmill rod linkage that has been stuck for years, left the penetrant overnight and easily unscrewed the two pieces of rod the next morning. Through the years I have used a number of products – from expensive penetrating oils to Coca Cola – to loosen stuck bolts and nuts, but this is the best product by far.
To test its cleaning, lubricating and rust preventive properties, I took my well-worn CZ75 pistol apart, sprayed everything thoroughly and left it to soak for about half an hour. On my return I found the clean white cloth beneath the parts soaked in a black slush as dirt was running out of crevices I normally could not get clean unless I used boiling water. I then wiped the parts dry and on closer inspection found that an old black stain on the outside of the chamber was gone. Through the years I have grown used to the discoloured stainless steel as various other products would not remove it.
After wiping the gun clean several times, I could still “feel” a thin film of lubricant, though it left no residue on my hands. More than a month later, the ever-present rust spots caused by wearing the pistol against my sometimes sweaty thigh have not re-appeared.
Suitably impressed, I used the oil on all my firearms, especially my working Mausers’ actions, which now feel smoother than when lubricated with my traditional oil. Cleaning dirty barrels has also become a much easier task as the lubricant does, in accordance with the manufacturer’s claim, remove carbon and copper fouling. I tested this on several occasions after returning from the range and in every instance the barrel cleaned with CorrosionX produced a clean patch (run through the barrel) much sooner than when I used my traditional cleaning chemicals.
