Brownells Inc OXPHO-BLUE LIQUID

Oxpho-Blue is a user-friendly bluing solution originally designed for occasional users, but favored by professional gunsmiths for its superior results. Simply dampen a piece of cotton flannel and rub the area—the chemical penetrates oil, removes thin rust, and blues the steel underneath without after-rust. While not intended to match the beauty of polished hot-blued guns, Oxpho-Blue can create a durable, weather-resistant finish in the hands of a careful craftsman. Key features include no after-rust, phosphate-like surface formation, rust removal, excellent wetting properties, and a highly durable finish that improves with rubbing. Ideal for firearms, tools, and instruments, Oxpho-Blue makes even worn guns look presentable with minimal effort.
