The gunky oil particles are sure to lead to a gun malfunction. To avoid this, gun lovers often choose to give their gun a regular thorough cleaning.
Are you worried about how to clean a shotgun? Don’t worry we’ve got you covered. Here are a few simple steps to keep your shotgun in good condition.
How To Clean A Shotgun Barrel?
There are people who never clean their guns and there are people who get their guns cleaned after every firing. You don’t have to belong to either of these categories and still maintain your shotguns in a good working condition.
Let’s take a look at a few basic steps to follow while cleaning a shotgun.
In the case of a semi-automatic shotgun, you have to carefully strip the gun into its prime parts. Make sure you are not in a public space, because there are chances that the screws or other tiny parts may go missing. For break action guns, you need to disconnect the forend from the barrels as the primary step.
Now cautiously remove it. In order to do this with a side-by-side or under shotgun, all you need to do is simply press the push button on the top. You can also do this by releasing the Auget. To disengage the barrels from the action hinge pins, make use of the unlocking lever to break the barrels completely. Ensure that the lever is fully open when you get this done. As a result, the barrels are detached from action.
On the other hand, you are required to unscrew the cap and remove the end of the magazine in the case of a semi-automatic shotgun. Slowly pull out the wooden forend. You can now separate the barrel. The barrel can easily be taken out of the receiver by applying a little force.
Moreover, you can also remove it with a few knocks of action. Now that the main parts of the gun have been disassembled, you can move onto the cleaning process.
Cleaning Operations
To start off with the cleaning process, you have to spray a little detergent gun oil into the barrel. This applies if you are intending to provide the gun a quick cleaning. You can also use an actual solvent if you want to give the shotgun a thorough cleaning.
Once you’re done with the spraying, the shotgun is to be placed on a horizontal workbench with care. Allow it to soak in for a few minutes. Now let’s get down to work.
While the gun rests, take a cloth piece and slightly dampen it with good quality gun oil. This aids you in cleaning the gun well. To begin with, diligently clean every part of the surface of the action or receiver. Try reaching every nook and corner by wiping perfectly around all the grooves.
By doing so, you will be able to eliminate traces of dirt and deposits, especially in the area around the hammers or firing pins. Use an old toothbrush or a short, stiff paint brush to clean hard-to-reach parts. As for holes and grooves, make use of a wooden toothpick.
Once you’ve gotten rid of all the dirt left by the firings, take a slightly oiled brush that is at least 4-5 cm. This brush will allow you to complete cleaning every tiny recess and places you couldn’t reach before. Also, make sure you thoroughly clean the places around the break hinge pins. Additionally, clean the areas around the seat of the recoil spring guide and the bolt guides on automatic guns.
You are now required to drip a few drops of lubricating oil into the unlocking lever’s mechanism. It is situated on the locking lugs, the release pin or the lever and the ejectors. While cleaning automatics, it is advisable to lubricate the extractor mechanism and the internal guides.
A compressor can be an amazing tool to use on automatics. Furthermore, the use of a detergent spray allows you to clean the firing mechanism well without the need to strip the gun much.
How To Clean Gas-operated And Reciprocating Barrel Semi-automatics?
In such kinds of shotguns it’s better to leave the area near the gas valve, pin and plunger clean yet dry. In the case of reciprocating barrel automatics, keep in mind to never lubricate the magazine tube, spring, and barrel friction rings.
Utilise a soft brass brush for chamois leather to clean the chequering of the wood. Follow the lines and cross over the grooves. Dip the brush in a drop of lemon oil or walnut oil to nicely clean the chequering.
Also, use a cloth dampened with oil to clean over the trigger guard, trigger, and the unlocking lever. Repeat the same with the outer and internal metal parts. Don’t forget to put them back in place as you go.
Place the barrel on a horizontal workbench in a safe and secure way. Ensure that you keep a thick rag below it for protection. And now swab well. To get this done, you need to fix a spiral phosphor bronze bore brush on a wooden rod. Spray the brush with oil and insert in the barrel from the action end.
You’ve got to swab at least 10-12 times. By pulling the brush all the way out at both the muzzle and the blocked ends, you’ll be able to clean thoroughly. Likewise, to clean interchangeable chokes, you need to take special care. Watchfully remove the chokes to clean the inside and outside of the delicate tubes. Furthermore, take particular care when you remove the part of the barrel that houses the chokes.
You will have to use a rough cloth to clean them. Alternatively, you can also make use of a fine steel wool pad. Moreover, if you utilise an effective product for cleaning stainless steel, the process will be easier for you. Such solvents will aid you in cleaning the gas plungers in gas-operated shotguns as well. Furthermore, it ensures that all the carbon, metallic, and plastic deposits left by the cartridges fired are eliminated.
It is very essential to tidy up the seat of the choke. Use a bore brush with a little bit of diesel or petrol to fully remove the residue from this delicate part of the barrel.
We’re almost there! The last step in the cleaning process is drying and the final cleaning. This can be done by using a piece of a clean rag threaded around the slot in the cleaning rod and slightly winding it around it. After drying the inner parts of the barrel, the bore and block should be polished well. Also, this should be done after changing the rag once or twice.
If you find a lot of fouling or matting on the insides of the barrel, it is best to wrap the bronze bore brush in a thin medium-coarse steel wool mat. This will effectively help you remove the stubborn deposits. Move the rag strip over the whole barrel and take an oily brush to apply a thin protective film all over the surface.
Before use, remember to wash the bronze bore brush in petrol and blow dry with a compressor. To prevent the brush from picking up dust and residue, keep it inside a plastic bag or a box. Use a cloth to clean the muzzle in a gentle way. Also, this will remove any trace of smoke and carbon remnants. And if it’s still difficult to remove, make use of a steel wool pad dipped in oil.
Lubricate all the moving parts with small drops of lubricating oil. You can finish it off by reassembling the gun by brushing it clean for one last time. Brush the rib and sling swivels neatly. Especially on hinges of break-action guns, it’ll be great if you add a little lithium grease, graphite grease, or white petroleum jelly.
Take into account the duration of your gun usage. If you won’t use the gun for many months, it’s a good idea to spray oil into the barrels. Additionally, swab with a wool pad to leave a thin film of oil for protection in each bore. Don’t forget to place the oiled wool swab inside a plastic bag or tube. This is done in order to dry out any accumulating dust or dirt.
For side-by-side and over/under shotguns, utilize a slightly oiled cloth to clean the inlay and the insides well. Use a brush to lubricate all the metal parts by paying extra attention to the ejector levers.
To sum up, it is really important to clean your guns and it is equally crucial to know how to clean a shotgun. Every now and then check your guns even while you’re not using them. This will help you keep the gun in a good condition.
