The Hoppe's No. 9 Bore Cleaner Foam delivers deep-cleaning action that penetrates fouling and lifts stubborn copper deposits from rifle and pistol barrels. This 12-ounce aerosol formula expands into hard-to-reach areas of the bore, breaking down powder residue and metal fouling that standard liquid cleaners often miss.
What Makes This Different
Unlike traditional bore cleaners that rely solely on chemical action, this foam formula clings to barrel surfaces for extended contact time. The expanding foam reaches into rifling grooves and chamber areas where liquid cleaners tend to run off quickly. This extended dwell time allows the active ingredients to work more effectively on embedded copper fouling and carbon buildup.Key Features
