Hoppe's No. 9 Black Powder Gun Bore Cleaner

Hoppe's No. 9 Black Powder Gun Bore Cleaner is the industry standard for shooters who rely on black powder rifles, shotguns, and historical firearms. This cleaner is purpose-formulated to dissolve and remove stubborn black powder residue, lead fouling, and copper deposits that accumulate in the bore and chamber. It has earned the trust of law enforcement, military armorers, and competitive shooters for over a century.

The proprietary formula works by chemically breaking down black powder residue and carbon buildup without requiring excessive scrubbing or extended soak times. This is critical for preserving bore condition and extending barrel life. Its strong penetrating action disperses into tight spaces around the rifling, making it effective for both rifle and shotgun applications where residue typically hardens as it cools.

Black powder shooters, historical firearms collectors, and gunsmiths rely on Hoppe's No. 9 as part of routine bore maintenance after each range session or hunting outing. Its effectiveness on both modern smokeless primers and traditional black powder loads makes it indispensable for maintaining firearm performance.
