Lucas Oil 10907 Extreme Duty Bore Solvent - Rust & Corrosion Protection, 4 oz Jar

Lucas Oil Extreme Duty Bore Solvent is a solvent-based cleaner formulated to handle the full spectrum of firearms fouling—carbon, powder residue, copper, and lead—in a single product. The 4 oz jar is sized for regular maintenance and range work, whether you're cleaning rifle barrels, handgun cylinders, or action components. This formula was engineered by a trusted manufacturer partner for shooters who want thorough cleaning without complexity: no mixing, no rinsing agents required, no separate oil dip needed after use. Just apply, let it work, and you're done.

The solvent base cuts through old oils and grease while depositing a micro-thin corrosion barrier on metal surfaces and bores—critical protection for firearms in storage or humid conditions. Because it contains no ammonia, kerosene, or water, it's safe on modern polymer frames and factory finishes, so you don't have to worry about stripping coatings or damaging components. The pleasant grape scent and low odor make bench work less unpleasant than ammonia-based alternatives.

Extreme Duty Bore Solvent is equally at home in an ultrasonic cleaner, where its high flash point (210°F) makes it suitable for heated tank systems without safety compromise. For the shooter who values efficiency—whether you're maintaining a single rifle or rotating through a larger battery—this solvent consolidates cleaning and light corrosion protection into one step, saving both time and money on additional products.

Frequently Asked Questions

Is Lucas Extreme Duty Bore Solvent safe to use in an ultrasonic cleaner?

Yes. The formula was specifically designed for ultrasonic cleaning, and its 210°F flash point makes it safe for heated ultrasonic units without additional precautions beyond manufacturer guidelines for your cleaner.

Will this solvent damage polymer or modern firearm finishes?

No. The formula is safe on polymers and factory-applied finishes, so you can use it confidently on modern frames, coatings, and treated surfaces without risk of stripping or degradation.

Do I need to add anything else after cleaning—like a rinsing agent or oil?

The solvent-based formula is used straight from the bottle without mixing. After ultrasonic cleaning, simply allow the firearm to drip dry or use compressed air, then lubricate per your manufacturer's instructions and reassemble. No rinsing agent or separate oil dip is required.

What fouling does this solvent remove?

The formula removes carbon and powder residue from actions, copper and lead fouling from barrels and cylinders, and old oils and grease from components.
