Product DescriptionBore Tech Cu+2 Copper Remover is engineered to meet the demands of precision shooters by removing stubborn copper fouling faster than traditional petro-ammonia solvents. Its proprietary two-step chemistry first oxidizes copper deposits, then binds and lifts them from the bore to prevent redepositing. The ammonia-free formulation is completely barrel safe and can be left to soak without etching or harming steel. A built-in short-term rust inhibitor protects and conditions the bore after cleaning for up to two weeks. Packaged in a user-friendly 4 oz bottle, Cu+2 delivers fast, thorough copper extraction for dependable firearm maintenance.Product HighlightsAdvanced two-step process oxidizes and lifts copper for complete extraction100% ammonia-free and barrel safe; safe for extended soak without etchingIncludes short-term rust preventative to protect bores for up to 2 weeksBiodegradable, non-hazardous formulation; non-flammable for safer useConvenient squeeze bottle with twist open/close dispensing cap and foam gasket sealSpecsProduct Type: Copper fouling remover (bore cleaner)Series: Cu+2Container Size: 4 ozForm: LiquidContainer Type: Bottle with twist dispensing capComposition: 2-Aminoethylphosphonic Acid, Water, Diethylene Glycol Monobutyl EtherFlash Point: > 266AdegFBoiling Point: 230AdegFVapor Pressure: 17 mm Hg at 68AdegFAppearance: AmberOdor: Mild pineFor Use With: FirearmsUPC: 667739980036Manufacturer Part Number: BTCU26004Brand Name: Bore TechDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
