Description
When your action is gummed up with carbon and old lube, sometimes patches and a brush just don't cut it. Birchwood Casey Gun Scrubber is a pressurized, fast-evaporating cleaner that does the heavy lifting for you. A quick blast pushes fouling and grime out of the internal metal parts, then flashes off dry so you can re-oil and get back to it. No wiping down for an hour, no soaking parts in a tray.
What the Gun Scrubber Aerosol Actually Does
The high-pressure jet is the real trick here. It literally blows built-up gunk out of the action, chambers, and gas ports where a brush can't reach. The included extension tube lets you pinpoint that spray into tight spots like magazines, barrels, and choke tubes. It leaves no residue when it dries, so once the grime is gone you just relube and you're finished. Regular use helps cut down on jams and keeps your gun cycling the way it should.
Guns the 13 oz Gun Scrubber Works On
This one earns its spot on the bench because it plays nice with just about everything. It's a solid choice for automatics, bolt guns, lever and slide actions, plus shotguns, air rifles, and muzzleloaders. Folks who shoot ARs especially like it for knocking loose the caked-on carbon that a CLP and toothbrush leave behind. It's also handy for cleaning your bore brushes and chamber brushes between jobs, so you're not scrubbing dirt right back into the next gun.
Worth Knowing Before You Spray
Gun Scrubber is a strong solvent built for internal metal parts. It can affect finished surfaces, plastics, laminates, composites, and rubber grips, so it's smart to hit an out-of-the-way spot first to see how your particular finish reacts. Use it in a well-ventilated space, and keep the good stuff on the metal where it belongs. Birchwood Casey has been making gun care products since 1948, and this can is a shop-tested standby for good reason.

Frequently Asked Questions
Does Gun Scrubber leave any residue on the parts?
No, it evaporates fast and leaves nothing behind once it dries. That's the whole appeal of an aerosol cleaner like this. After you blast the fouling loose, just re-oil and lubricate your firearm and you're good to go.
Can I spray the Gun Scrubber aerosol on grips and plastic parts?
This is a strong solvent meant for internal metal parts, and it can affect finished surfaces, plastics, laminates, composites, and rubber grips. Test a hidden spot first to see how your finish holds up. To be safe, aim it at the metal and steer clear of the plastic and wood.
What kind of firearms is the 13 oz Gun Scrubber good for?
It covers a wide range, including automatics, bolt actions, lever and slide guns, shotguns, air rifles, and muzzleloaders. That means one can can handle pretty much everything in the safe. AR shooters lean on it hard for clearing baked-on carbon that a brush struggles with.
How do I reach tight spots like gas ports and choke tubes?
The can comes with an extension tube that snaps onto the nozzle for a focused, high-pressure stream. That lets you drive the cleaner right into actions, magazines, gas ports, chambers, barrels, and choke tubes. It's the easiest way to flush grime out of spots your brush can't touch.
