Brownells Tank Solvent, 1 Gallon

Brownells Tank Solvent is a petroleum-based cleaning solution designed for bench-top dunk tanks and soak cleaning setups. Whether you're running a dedicated cleaning station or working from a bucket, this 1-gallon container delivers dependable solvent action for dissolving stubborn powder fouling, dirt, and hardened gun oil that accumulates in action crevices and hard-to-reach areas. The formulation suspends dissolved crud in solution so it rinses away cleanly without leaving residue behind.

The chemistry here includes organic additives that work on the gummy combination of residue buildup that standard cleaners struggle with—the kind of carbon and oil sludge that settles in bolt lugs, firing pin channels, and around springs. After the cleaning work is done, Brownells Tank Solvent leaves a light oily film that guards against surface rust and flash, buying you time before you need to apply a protective oil or grease for storage or transport.

One of the practical advantages of this solvent is its extremely slow evaporation rate. It stays effective in your tank for extended use, so you're not constantly topping it off or dealing with thickened, less effective cleaning fluid. The formulation is nearly odorless—a real advantage if you're cleaning indoors or in a shared space. It's also stable and non-corrosive to steel and iron parts, meaning extended soak times won't damage your firearms. Cleanup is straightforward: Brownells Dicro-Clean 909 removes residual solvent easily, and because this product won't interfere with bluing or plating processes, it's safe to use before sending guns out for refinishing work.

One caveat: avoid contact with painted surfaces, plastics, and some wood stock finishes, as the solvent can damage these materials. Store securely and use in well-ventilated areas for safety.

Yes. This solvent is formulated specifically for slow-soak and dunk applications in bench-top cleaning stations or buckets. Its slow evaporation rate means it remains effective during extended soaks without losing potency.

Will this solvent damage my gun's finish or bluing?

The solvent itself is non-corrosive to steel and iron, and it won't interfere with bluing or plating processes—making it safe for extended contact with bare metal parts. However, avoid contact with painted surfaces, plastics, and certain wood stock finishes, as the solvent can damage these materials.
