Lucas Oil Extreme Duty Bore Solvent is a professional-grade cleaning solvent built for shooters who want deep, effective firearm maintenance without the mess or guesswork. This 64-ounce solvent removes carbon fouling, powder residue, copper, and lead buildup from barrels, cylinders, and actions while leaving behind a thin corrosion-inhibiting film. It's trusted by major firearms manufacturers and works straight from the bottle—no mixing, no rinsing agent needed, no separate oil dip required after cleaning.

What sets this solvent apart is its versatility and safety profile. The formula is engineered specifically for ultrasonic cleaners, with a flash point of 210°F, making it suitable for heated ultrasonic tanks where standard solvents become a hazard. It cuts through old oils and grease effectively while staying safe on polymer frames and factory finishes. After ultrasonic cleaning, you simply drip-dry or use compressed air, then lubricate per your firearm's manual and reassemble—your gun is clean, protected, and ready to go.

The solvent contains no ammonia or kerosene and carries a pleasant grape scent with low odor, making shop time more tolerable. Whether you're running a high-volume cleaning routine with ultrasonic equipment or doing hand cleaning on the bench, this solvent handles carbon and fouling efficiently and leaves your bore and action protected against rust and corrosion. It's the kind of reliable, no-nonsense product you'd expect from a brand that works directly with manufacturers.
