Thompson Center 9030R T17 FOAMING BORE CLEANER 7 OZ.
The Thompson Center T17 Foaming Bore Cleaner is purpose-built for muzzleloader shooters who want a faster, less labor-intensive way to manage black powder fouling. Whether you shoot traditional black powder or modern substitutes, this 7 oz. aerosol spray tackles stubborn bore deposits without requiring you to run a brush through the barrel repeatedly—just spray, wait, and wipe.
Black powder and substitute powders leave heavy, caked-on residue that can compromise accuracy and invite rust if left untreated. T17's foaming action penetrates deep into those deposits, breaking them down so you can remove them with a simple wipe. The cleaner also addresses copper and lead buildup that accumulates over shooting sessions, helping restore your bore to a cleaner state. Once the bore is clean, the formula leaves behind a micro-thin protective layer that guards against rust and corrosion between shooting trips.
The convenience factor is real: spray the bore, let it sit for about an hour, and the foam does the heavy lifting. No aggressive scrubbing, no extended soak times. For muzzleloader hunters and range shooters who want faster cleanup without sacrificing bore protection, this is a genuine time-saver. Thompson Center recommends following up with their T17 Seasoning patches to maintain that protective barrier.
