I Tested WD-40, Hoppe's, Ballistol & Motor Oil On Guns — A Clear Winner!

Stop wrecking good guns with the wrong can. After four decades as a gunsmith, I’ve seen firsthand how "counter talk" and clever marketing lead to gummed-up actions, rusted bores, and dead primers. In this video, I put the four fluids most likely to be in your garage or range bag—WD-40, Hoppe’s No. 9, Ballistol, and even Motor Oil—to an honest, three-part test. We evaluate each product based on real chemistry: does it actually clean, does it lubricate under pressure, and does it protect your steel during long-term storage? You’ll discover why a water displacer is the "villain" of your gun safe, why a legendary American solvent is only half a system, and how a quart of synthetic motor oil is a secret budget-saver for high-friction parts. Finally, I reveal the century-old winner that neutralizes acidic fouling and handles every job in a single bottle. Take care of your guns, and they'll take care of you.
