Description
You’re at the bench after a long range day. The smell of burnt powder hangs in the air, and your rifle’s bore is a dark tunnel of carbon and copper fouling. You need a solvent that cuts through the grime without a fight, one that preserves your barrel’s life and your time. That’s the mission of the Thompson Center No. 13 Bore Cleaner 8oz. It’s a specialized, non-ammoniated solvent engineered to safely and effectively remove powder residue, lead, and plastic fouling from shotgun, rifle, and pistol bores. This 8-ounce bottle provides a reliable supply for maintaining multiple firearms, ensuring your tools are clean, protected, and ready for their next use. Available at firearms-missouri.com for Missouri residents and nationwide.
When it comes to home defense or competition prep, a neglected bore can mean the difference between a center-hit and a flyer. The Thompson Center No. 13 formula attacks fouling without the harsh chemicals that can degrade steel over time. It’s designed for the practical shooter who values function over fuss—no complicated procedures, just a proven clean. Apply it to a patch, run it through, and follow with a dry pass. The solvent works to break down stubborn deposits, making the final polishing step straightforward. For the price of $16.51, it’s an affordable investment in firearm longevity.
Key Features
This cleaner’s primary advantage is its targeted action. It’s formulated specifically for the common fouling types left by modern ammunition, dissolving them so they can be wiped away rather than requiring aggressive mechanical scrubbing that can wear rifling. This non-abrasive approach is critical for maintaining the precise dimensions of a match barrel or the smooth bore of a defensive shotgun.
Compatibility is broad. It works safely on blued, stainless, and nickel-plated barrels, making it a versatile single-bottle solution for a diverse collection. Whether you’re maintaining a classic Winchester Model 70, a modern Ruger American, or a duty-ready Remington 870, this solvent handles the job. The application is straightforward—no gunsmithing required, just basic cleaning tools. Its effectiveness on plastic fouling also makes it a top choice for shotgun enthusiasts who run a lot of target loads.

Pros & Cons
Pros: Effective on multiple fouling types; safe for common barrel finishes; non-abrasive formula protects rifling; convenient 8oz size offers solid value; simple, no-fuss application process.
Cons: As a specialized bore cleaner, it is not an all-in-one lubricant or protectant—you’ll need separate products for those final steps. The bottle design is functional but basic.
Who It’s For
This cleaner is for the shooter who maintains their own tools and understands that consistency starts with a clean barrel. It’s ideal for the hunter cleaning a season’s worth of fouling from a Thompson Center Compass, the tactical shooter maintaining a Sig Sauer P320, and the clay shooter servicing their over-under. If your philosophy is “clean it right, keep it simple,” this solvent fits your bench.
Frequently Asked Questions
Q: Is this cleaner safe for all barrel types?
A: Yes. The non-ammoniated formula is specifically designed to be safe for blued, stainless, and nickel-plated barrels. It effectively removes fouling without damaging the metal substrate or finish.
Q: How does it handle tough copper fouling?
A: Thompson Center No. 13 Bore Cleaner is formulated for powder, lead, and plastic fouling. For severe or stubborn copper fouling, a dedicated copper solvent may be more effective. For general range use and maintenance, however, this cleaner handles the majority of common deposits.
Q: What’s the best way to apply it?
A: Apply a small amount to a clean patch and run it through the bore from chamber to muzzle. Let it sit for a few minutes to penetrate, then follow with dry patches until they come out clean. Always ensure proper ventilation during use.
