This "Smyth Busters" episode debunks the myth that WD-40 is a suitable lubricant for firearms. Brownells Gun Techs Caleb and Steve strongly advise against its use, explaining that WD-40 is a water displacer, not a true lubricant. While it may offer temporary slickness, it can become gummy and gum up gun actions over time. The video suggests using WD-40 to displace water from a submerged firearm but emphasizes immediate removal and application of proper gun oil or CLP. It also provides a method for cleaning off sticky WD-40 residue.
