Thompson Center 9018R NUMBER 13 BORE CLEANER 8-OZ BOTTLE
Thompson Center Number 13 Bore Cleaner is a specialized solvent formulated specifically for muzzleloader barrels. This 8-ounce squeeze bottle delivers an all-natural cleaning solution that cuts through fouling and residue buildup without stripping away the seasoning layer that protects your bore. If you shoot traditional black powder or inline muzzleloaders, you already know that bore maintenance is part of the commitment—Number 13 makes that job genuinely fast and efficient, so end-of-hunt cleanup becomes a quick task instead of a chore.
What sets Number 13 apart is its composition: it contains no petroleum-based additives, which means it works in harmony with Thompson Center's Natural Lube 1000 Plus and respects the traditional seasoning that muzzleloader shooters depend on. The cleaner is non-toxic and odorless, so you can use it indoors, in your workshop, or in the field without worrying about fumes or disposal headaches. The 8-ounce squeeze bottle is sized for transport and storage—compact enough to stash in a range bag or truck, practical enough to have on hand whenever you finish a hunt or a shooting session.
Whether you're running a traditional flintlock, percussion cap rifle, or modern inline, muzzleloader barrel care directly affects your rifle's reliability and accuracy. Number 13 does the heavy lifting on residue removal, leaving you more time to focus on the rest of your cleaning routine and prep work for your next trip afield.
