Gun Cleaning Basics: What to Do When Your Auction Win Arrives

Your auction win just arrived at your FFL dealer. You've completed your Form 4473, paid the transfer fee, and you're walking out with a firearm that may have been sitting in someone's safe for a decade. Before you load a single round, there are things you need to check and do.

This isn't about making a used gun look pretty. It's about verifying it's safe and functional — and building the maintenance habits that keep it that way.

Step 1 — The Initial Inspection (Before You Clean Anything)

Before you touch a cleaning rod or a patch, do a thorough visual and tactile inspection:

• Verify the chamber is empty. Lock the action open, remove any magazine, and visually and physically confirm no round is present.
• Check for obvious damage. Cracks in the stock, deformation around the muzzle, rust inside the action, or evidence of amateur gunsmithing (stripped screws, mismatched parts) should go to a gunsmith before shooting.
• Inspect the bore. Use a bore light or hold it up to a strong light source. You should see clean rifling with no bulges, pitting, or obstructions. Light fouling is normal. Heavy pitting or a keyhole shape means professional inspection before shooting.
• Test the action manually. Cycle through the action by hand. It should be smooth, with positive lockup. Gritty resistance or failure to fully cycle suggests a cleaning issue, or a mechanical one that needs a gunsmith.
• Check safety function. Engage and disengage the safety. It should actuate positively and the trigger should not move when the safety is on.

Your First-Clean Supply List

The First-Clean Routine

1. Field strip the firearm according to the manufacturer's manual. Do not disassemble beyond field-strip without cause — you'll lose small parts and create problems you didn't have before.
2. Clean the bore with a bronze brush and solvent, pushing from chamber to muzzle. Run patches until they come out clean. For old carbon buildup, a 10-minute soak with solvent on a patch can help.
3. Clean the action. Use a nylon brush and solvent to remove carbon and old lubricant from all moving surfaces. An old toothbrush works well for recesses. Pay attention to the feed ramp and extractor area on semi-autos.
4. Dry everything. Solvent left on metal does nothing useful. Run dry patches, wipe down all surfaces, and let parts air for a few minutes before lubricating.
5. Lubricate correctly — less is more. A thin film of oil on friction surfaces is correct. Excess oil attracts carbon and gums up in cold weather. For most handguns and rifles, four to six small drops in the right places is the entire lubrication job.
6. Function check before loading. Reassemble, point in a safe direction, and manually verify all controls operate correctly. Rack the action fully, check safety operation, and verify the trigger resets after dry-fire (check your state and local laws on dry-fire before doing so).

"A gun that hasn't been shot in ten years is not a dangerous gun. A gun that hasn't been inspected in ten years might be. Those are different problems, and cleaning addresses one of them."

When to Go to a Gunsmith Instead

Not every issue is a cleaning problem. Take your auction win directly to a qualified gunsmith before shooting if you find: visible bore damage or obstructions, cracked or damaged receiver, ammunition stuck in the chamber, function that doesn't normalize after cleaning, or any signs of amateur repair work (improper welds, wrong parts, removed manufacturer markings).

A $40 inspection by a qualified gunsmith before your first range trip is cheap insurance.
