Hoppe's No. 9 Foaming Bore Cleaner Bottle 3.0 oz

Hoppe's No. 9 Foaming Bore Cleaner Bottle 3.0 oz is the industry standard for rapid firearm maintenance in the field and at the bench. Trusted by law enforcement, military personnel, and serious shooters for decades, this one-step bore cleaner eliminates the need for time-consuming mechanical scrubbing or additional cleaning agents. The compact 3.0 oz bottle delivers professional-grade cleaning power in a portable format, making it an essential component of any tactical or range bag.

The foaming action works by chemically dissolving both copper fouling and powder residue that accumulate during fire, allowing contaminants to be flushed away without abrasive brushing that can wear bore integrity over time. This proprietary formula penetrates carbon buildup and oxidized copper deposits, neutralizing them for effortless removal with a patch or rod pull-through. The visible color-change indicator confirms cleaning effectiveness—the solution darkens as it encounters bore fouling, giving you visual feedback on when your bore reaches optimal cleanliness without guesswork.

Law enforcement and military armorers rely on Hoppe's No. 9 for routine maintenance of rifles, carbines, handguns, and shotguns across all common calibers. The 3.0 oz size is ideal for shooters who conduct regular post-range cleaning or field maintenance during extended operations where bore condition directly impacts accuracy and reliability. Compatible with all modern firearm materials including chrome-lined and stainless steel bores, this cleaner is the choice of professionals who demand consistent, repeatable results without solvents that degrade seals or finishes.
