Introduction
The AK-47 has a reputation for being indestructible. You have likely heard the stories of rifles buried in mud for years or dragged through swamps, only to fire perfectly the moment the trigger is pulled. While the platform is legendary for its loose tolerances and reliability, no machine survives forever without maintenance. Carbon buildup, copper fouling, and the salts from corrosive ammunition will eventually degrade accuracy and lead to catastrophic failure. At Crate Club, our team of Special Operations veterans has seen gear fail in the most demanding environments, and we know that maintenance is a non-negotiable part of the tactical mindset. If you want field-tested gear to support that mindset, start by choosing the Lieutenant tier. This guide will walk you through the professional process of cleaning your AK-47, ensuring your rifle remains a reliable tool for self-defense or survival. We will cover field stripping, deep cleaning the gas system, and the critical steps for neutralizing corrosive salts.
Quick Answer: To clean an AK-47, field strip the rifle into its main components: the dust cover, recoil spring, bolt carrier group, and gas tube. Use a high-quality solvent to remove carbon from the piston and bolt, clean the bore from breech to muzzle, and apply a light coat of lubricant to friction points before reassembling.
The Importance of AK-47 Maintenance
The AK-47 operates on a long-stroke gas piston system. This means the gas piston is physically attached to the bolt carrier group (the internal component that moves back and forth to cycle rounds). When you fire a round, gas is diverted from the barrel into the gas block, pushing the piston back. This process is effective but inherently dirty. Carbon and lead deposits accumulate quickly on the piston head and inside the gas tube.
If you are using surplus ammunition, maintenance becomes even more critical. Much of the affordable 7.62x39mm or 5.45x39mm surplus ammo on the market uses corrosive primers. These primers contain potassium chlorate, which leaves behind salt deposits (residue) in the barrel and gas system after firing. These salts attract moisture from the air, causing rapid rust and pitting in the bore. Even a chrome-lined barrel can eventually succumb to this if neglected.
Field Note: Never trust a "chrome-lined" barrel to prevent all rust. Corrosion can still start in the gas block or on the bolt face. If you shoot surplus ammo, you must clean the rifle the same day you hit the range.
Essential Cleaning Supplies
Before you begin, you need the right tools. You do not need an expensive, specialized bench setup, but you do need components that can handle the heavy carbon of a piston-driven rifle.
- Cleaning Rod: Most AKs come with one under the barrel, but a high-quality brass or coated steel rod is better for regular use.
- Bore Brush: Match this to your caliber (usually .30 caliber for 7.62x39mm).
- Jags and Patches: For wiping the bore clean.
- CLP (Cleaner, Lubricant, and Preservative): A versatile solution that handles all three tasks.
- Dedicated Solvent: Useful for heavy carbon on the gas piston.
- Nylon or Brass Brush: To scrub the bolt face and carrier.
- Clean Rags or Microfiber Cloths: For wiping down large surfaces.
- Flashlight: To inspect the bore and gas block for debris.
Many of these items are frequently featured in our Gear Shop, which is a good place to browse practical cleaning and maintenance tools.
Safety First: Clearing the Weapon
Before any maintenance begins, you must ensure the rifle is completely unloaded. This is the most critical step in the process.
- Remove the Magazine: Press the magazine release lever and pull the magazine out of the mag well.
- Cycle the Action: Pull the charging handle back sharply several times to eject any round that might be in the chamber.
- Visual Inspection: Lock the bolt to the rear (if your rifle has a bolt-hold-open notch) or hold it back. Look into the chamber to verify there is no brass.
- Physical Inspection: Stick a finger into the chamber to feel for a round. This is especially important in low-light environments.
- Remove Ammunition: Move all live ammunition to a separate room or a distant part of your workbench to prevent accidental loading.
Field Stripping the AK-47
Field stripping refers to taking the rifle down to its primary component parts for cleaning and inspection without the use of specialized tools.
Step 1: Remove the Dust Cover
The dust cover is the metal shell on top of the receiver. To remove it, push the rectangular button (the rear of the recoil spring assembly) located at the back of the receiver. While holding the button in, lift the rear of the dust cover up and away from the rifle.
Step 2: Remove the Recoil Spring
Push the recoil spring assembly forward (toward the muzzle) until it clears the grooves in the rear of the receiver. Lift it up and pull it straight out of the back of the bolt carrier.
Step 3: Remove the Bolt Carrier and Bolt
Pull the charging handle all the way to the rear. At the very back of the receiver, there are notches that allow the bolt carrier to be lifted upward. Lift the carrier out. To remove the bolt from the carrier, push the bolt to the rear of the carrier, rotate it, and pull it forward and out of the carrier track.
Step 4: Remove the Gas Tube
Located on the right side of the rear sight block is a small lever. Rotate this lever upward (usually to a 45-degree angle). Do not force it past its natural stop. Once the lever is up, you can lift the rear of the gas tube up and pull it away from the gas block.
Key Takeaway: The AK-47 is designed for simplicity. If you have to use a hammer or extreme force to field strip the rifle, something is wrong. Check the alignment of the parts and the position of the takedown levers.
Cleaning the Components
The Barrel and Chamber
The barrel is the heart of your rifle's accuracy. Always clean from the breech (the rear) to the muzzle when possible to avoid damaging the crown. The crown is the very end of the barrel where the rifling terminates; any nick here will cause the gas to escape unevenly, throwing off your MOA (Minute of Angle, a measurement of accuracy).
For a broader look at what maintenance schedules should feel like in practice, how often you should clean your hunting rifle is a useful follow-up. Apply solvent to a bore brush and run it through the barrel 10 to 15 times. Let the solvent sit for a few minutes to break down copper and carbon. Follow this with dry patches on a jag until they come out clean. Finally, run a patch with a light coat of oil through the bore to prevent rust.
The Bolt and Bolt Carrier Group (BCG)
The BCG is where most of the mechanical action happens. Use a nylon brush and solvent to scrub the bolt face. Pay close attention to the extractor—the small claw that pulls the spent casing out of the chamber. Carbon buildup under the extractor can lead to failures to extract.
The gas piston (the long rod attached to the carrier) will likely be covered in hard, black carbon. You can use a brass brush or even a specialized carbon scraper to get this clean. It does not need to be shiny like a mirror, but you should remove any thick "crust" that has formed.
The Gas Tube and Gas Block
The gas tube is a hollow pipe that directs gas back to the piston. Because it is a simple tube, you can use a large bore brush (like a 12-gauge shotgun brush) or a rag wrapped around a rod to wipe out the interior. Inspect the gas block (where the tube connects to the barrel) for any obstructions. A clogged gas port will turn your semi-automatic rifle into a single-shot bolt action.
Dealing with Corrosive Ammunition
If you have been shooting "spam can" surplus ammo, standard CLP might not be enough. The salts left behind are water-soluble. Professional operators and experienced preppers often use a mixture of hot water and soap, or specialized ammonia-based cleaners, to flush the barrel and gas system before starting the standard cleaning process.
If you want a related look at how ammunition choice affects maintenance, are steel cases bad for your gun is a helpful comparison.
The Water Flush Method:
- Pour hot, soapy water down the barrel and through the gas tube.
- Rinse with clean water.
- Immediately dry the components using compressed air or patches.
- Proceed with your standard solvent and oil cleaning.
The water neutralizes and washes away the salts that cause rust. If you skip this step and only use oil, the salts can remain trapped under the oil layer and continue to eat away at the metal.
Proper Lubrication Points
The AK-47 does not need to be soaked in oil, but it does need lubrication on high-friction surfaces. Over-lubricating can actually be a disadvantage in sandy or dusty environments, as the excess oil will attract grit and turn into a "grinding paste."
If you want to round out the tools you keep on hand, browse the Gear Shop for practical maintenance gear and field-ready accessories.
Apply a light coat of oil or grease to:
- The rails on the inside of the receiver where the bolt carrier slides.
- The tail of the bolt where it interacts with the carrier.
- The cam pin track on the bolt carrier.
- The hammer face (where it strikes the firing pin).
- The recoil spring assembly guide rod.
Do not put oil inside the gas tube or on the gas piston head. These areas get extremely hot, and the oil will simply burn off or create a sticky sludge that hinders performance.
Field Note: In extreme cold, use a dry lubricant or a very thin synthetic oil. Standard grease can thicken in sub-zero temperatures, slowing down the action and causing light primer strikes.
Reassembly and Function Check
Once everything is clean and lubricated, reverse the field stripping steps to put the rifle back together.
- Insert the Gas Tube: Seat the front into the gas block and lower the rear into the sight block. Rotate the lever down to lock it.
- Assemble the Bolt: Drop the bolt into the carrier, rotate it, and pull it forward into the locked position.
- Install the BCG: Align the piston into the gas tube and the carrier into the receiver tracks. Push it forward until it seats.
- Install the Recoil Spring: Slide the spring into the carrier and lock the rear into the receiver notches.
- Replace the Dust Cover: Seat the front of the cover in the groove near the sight block and snap the rear down over the recoil spring button.
The Function Check
Before you consider the job done, perform a function check to ensure the rifle is safe to operate:
- Ensure the rifle is clear.
- Charge the action and pull the trigger (pointed in a safe direction). You should hear a "click."
- Hold the trigger down and cycle the action again.
- Slowly release the trigger; you should hear a "clack" as the sear resets.
- Engage the safety and attempt to pull the trigger. The trigger should not move, and the hammer should not fall.
Bottom line: A clean AK-47 is a reliable AK-47. Regular maintenance prevents corrosion, ensures smooth cycling, and extends the life of your rifle for decades.
Advanced Maintenance: Beyond the Field Strip
For the serious tactician, occasional deep cleaning involves looking at the furniture and the trigger group. If your AK has wooden furniture, check for cracks or places where oil has soaked into the wood, which can soften it over time. If you have modern polymer furniture, ensure all mounting screws are torqued to spec.
The trigger group (the FCG or Fire Control Group) usually stays relatively clean, but it can accumulate blown primers or brass shavings. Use compressed air or a brush to clear out the bottom of the receiver. We often include high-performance tools and cleaning accessories in our Major tier crates that make these deep-cleaning tasks much easier for the experienced owner.
Maintaining Your Cleaning Kit
Your cleaning kit is a piece of tactical gear just like your rifle. If your brushes are flattened or your solvent bottles are leaking, you won't be able to maintain your weapon in the field. Periodically inspect your kit. Replace worn brushes and ensure you have an ample supply of patches.
If you are building a "Go Bag" or a SHTF (Sh*t Hits The Fan) kit, include a compact cleaning kit. A pull-through bore cleaner (like a BoreSnake) is excellent for a quick field clean when you don't have the space for a full rod set. However, a pull-through should never replace a thorough rod cleaning for long-term maintenance. A good example of the kind of practical support gear that belongs in a preparedness kit shows up in Supply Drop - Lieutenant VII.

FAQ
How often should I clean my AK-47?
If you are shooting non-corrosive, modern ammunition, you should perform a basic field strip and clean every 500 to 1,000 rounds. However, if you are using corrosive surplus ammunition, you must clean the rifle the same day you shoot it to prevent rust. Even if you haven't fired the rifle, a quick wipe-down and re-lubrication every few months is recommended if you live in a humid environment. For broader maintenance planning, the subscription pages can also help you pair your kit with the right level of gear support.
Do I really need to use water to clean after shooting corrosive ammo?
Yes, because the corrosive salts left by the primers are not dissolved by oil or most standard gun solvents. Water is the most effective and cheapest way to dissolve these salts and flush them out of the barrel and gas system. After using water, you must dry the rifle completely and apply oil to prevent flash rusting.
Can I over-clean my rifle?
You can damage a rifle by cleaning it improperly, such as by using a steel cleaning rod from the muzzle end, which can wear down the crown and ruin accuracy. However, cleaning the components with the proper tools and solvents will not "wear out" the metal. The key is to use the right materials—like brass brushes and coated rods—and to follow the correct procedure.
What are the most important parts of the AK to lubricate?
Focus on the parts that move against each other. The receiver rails, the bolt carrier's underside, the cam track on the bolt carrier, and the hammer face are the primary friction points. Avoid putting oil in the gas system, as the extreme heat will cause the oil to carbonize and potentially gum up the action.
