Hoppe's No. 9 Black Powder Gun Bore Cleaner

Hoppe's No. 9 Black Powder Gun Bore Cleaner is a purpose-formulated solvent designed specifically for shooters who fire traditional black powder firearms. This dual-action cleaner removes powder fouling and residue from the bore while simultaneously lubricating the barrel, eliminating the need for separate cleaning and protection steps in your maintenance routine.

The formulation works equally well on both shallow and deep-grooved barrels, adapting to the varied rifling profiles common in historical and modern black powder rifles, pistols, and shotguns. As the solvent dissolves fouling deposits, it leaves a protective lubricant film that guards against rust and corrosion—a critical consideration for black powder shooters, since black powder combustion produces hygroscopic residue that attracts moisture when left untreated. This integrated approach reduces the number of products needed in your gun cleaning kit and shortens total maintenance time at the range or in the field.

Black powder enthusiasts—whether engaged in historical reenactment, competition shooting, hunting with traditional arms, or preserving antique firearms—depend on cleaning solvents that address the unique chemistry of black powder fouling. Standard modern firearm cleaners often fall short because they're formulated for smokeless residue, not the corrosive salts left by black powder combustion. Hoppe's No. 9 Black Powder formula bridges that gap, making it an essential component of responsible black powder firearm ownership and safe storage practices.

The 0.57 lb bottle provides efficient coverage for multiple cleaning sessions, and the compact 1.8 x 1.8 x 7 inch dimensions fit easily into shooting bags, cleaning kits, or home storage. Serious black powder shooters often maintain multiple firearms in this category and appreciate a solvent they can trust across their entire collection.
