Description
You know the feeling. After a long day at the range, the last thing you want is a complicated, hours-long cleaning ritual. You just want a solvent that works—no fuss, no strong lingering odors, and no damage to your prized barrel. That’s the practical problem the Thompson Center Number 13 Plus Bore Cleaner Spray Bottle 8 Ounce solves. It’s a straightforward, effective formula designed to cut through powder fouling and copper residue without breaking the bank or your patience.
Answer Capsule: The Thompson Center Number 13 Plus Bore Cleaner is an 8-ounce spray bottle of bore solvent designed for removing powder, lead, and copper fouling from firearm barrels. It’s a non-ammoniated, low-odor formula that works on rifles, shotguns, and pistols, offering a practical cleaning solution for the budget-conscious shooter who values efficiency.
Here’s the thing—you don’t need a boutique cleaner costing twice as much for routine maintenance. Number 13 Plus gets the job done. Its spray bottle application is a key feature, allowing for direct, controlled delivery right onto patches, brushes, or into the chamber. This minimizes waste compared to sloppy pours from a large can. The formula is non-ammoniated, which is a major plus for preserving the steel in your barrel over the long term, especially on modern rifles. It’s designed to be effective yet less aggressive, meaning no gunsmithing required for its use—just apply, let it work, and scrub or patch it out.
Compatibility is broad. Whether you’re maintaining a classic hunting rifle like a Remington 700, a modern sporting AR-15, or your everyday Glock 19, this cleaner is up to the task. It’s formulated for all common barrel steels. The 8-ounce size is a sweet spot, providing enough cleaner for dozens of range sessions without taking up much space in your cleaning kit. At $18.35, it sits in a very competitive price bracket, often coming in lower than many 4-ounce bottles of specialized copper removers. For general fouling removal, it represents serious bang-for-your-buck.

Pros & Cons
The clear advantage is value. You get a proven, T/C-branded formula in a convenient sprayer at a very fair price point. The low-odor aspect is a genuine benefit for those cleaning indoors or in confined spaces. Being non-ammoniated protects your barrel’s integrity. The tradeoff? For extremely heavy or stubborn copper fouling, a dedicated, stronger copper solvent might be marginally faster. This is a cleaner for regular maintenance, not necessarily for reviving a severely neglected barrel. That said, for 95% of shooters, it’s more than sufficient.

This cleaner is ideal for the practical shooter. The hunter who needs to clean their bolt-action after a season. The pistol owner who puts a few hundred rounds through their SIG P320 each month. The budget-minded AR-15 enthusiast who maintains multiple uppers. It’s for anyone who wants a reliable, no-nonsense cleaner that performs well without premium branding or price. It’s available at firearms-missouri.com for Missouri residents and nationwide.
