Premium Gun Cleaner, Lubricant and Rust/Corrosion Preventative
BLU protects your investment under extreme weather conditions. Gunsmiths, hunters, sport shooting enthusiasts and competitive shooters choose their carefully balanced formula for its superior cleaning, lubrication and protection.
Use BLU to prevent rust and corrosion—even when firearms and knives are exposed directly to salt and fresh water. Laboratory ASTM B117 salt-fog tests prove BLU protects up to 300% longer than leading gun oils.
BLU goes on fast, flashes off quickly and dries to a protective barrier that is never oily or tacky. Surfaces won’t pick up dust, grit or grime or even show fingerprints.
BLU protects factory-blued barrels and steel parts from corrosion and moisture. It cleans, lubricates and prevents rust inside chambers, receivers and actions. BLU even dissolves surface rust. Supported and endorsed by leading gun manufacturers.
