Hoppe's No. 9 Powder Solvent 4oz

Hoppe's No. 9 Powder Solvent 4oz is the industry-standard bore cleaner trusted by law enforcement, military personnel, and competitive shooters worldwide for over a century. This solvent is purpose-built to dissolve and remove powder residue, primer fouling, lead deposits, and copper/metal buildup from rifle and pistol barrels. Whether you're maintaining duty weapons, cleaning match firearms, or performing routine field maintenance, Hoppe's No. 9 delivers the cleaning power and safety profile demanded by professionals who depend on firearm reliability.

The formula works by rapidly penetrating carbon and fouling deposits, breaking down hardened residue without requiring excessive scrubbing or soak time—critical when you need efficient cleaning between range sessions or field operations. Its low volatility and measured evaporation rate allow the solvent to remain active on bore surfaces long enough to be fully effective, while the controlled composition prevents the aggressive corrosion issues associated with harsher chemicals. The 4oz size is ideal for portable field kits, tactical go-bags, and regular maintenance without excess storage; it flows freely through patches and brushes, ensuring complete contact with interior bore walls and action surfaces.

Law enforcement armorers, military gunsmiths, and civilian marksmen rely on Hoppe's No. 9 for routine bore maintenance across all common rifle and pistol calibers, from .22 rimfire through .50 BMG platforms. The solvent is compatible with all standard cleaning rod systems, patches, and brass brushes, and works effectively on all barrel steel types and finishes. After solvent treatment, a light oil film prevents flash rust, making it the first choice for shooters who prioritize bore longevity and consistent accuracy. This compact 4oz bottle meets HAZMAT shipping standards and delivers professional-grade cleaning results at a fraction of the cost of bore obstruction removal services.
