Before You Start
Use an uncluttered working table, workbench or surface to take apart your gun – this will save time later, looking for all the parts, screws and tools you need to put the gun back together.
The first step in how to clean a paintball gun is to de-gas it entirely – you don’t want any accidental shots being fired while you’re working on it! Make sure you take out the fuel canister or CO2 tank and then find the ASA lever to de-gas it. If yours does not have one of those levers, check the manual for the model, and find the method to de-gas it completely.
2. Disassemble the Paintball Gun
The next step in how to clean a paintball gun is to disassemble the entire thing. You make a start with the hopper and air tank, and then work your way around the rest of it. Remove the bolt, the hammer, barrel, and the grip frame. It is a good idea to keep all of these items aside with all of their bolts & fasteners placed with them so that you can put it all back together quickly.
3. Clean the Barrel
Next up, you have to clean the barrel of the marker. Use a purpose-made paintball marker swab you can pull through the barrel (like this one). Clear out the barrel rigorously, so you remove all signs of built-up paint or chopped paintballs in there. If you leave the paint residue there, it can cause your gun to jam up.
If it’s still not clean after using a swab, you can also use a squeegee. Once you’re done cleaning out the paint, give it a proper wipe down with a paper towel so that it’s dried.
4. Clean the Body
Next, the body. Check your marker’s manual to confirm if your model’s body can be cleaned with a squeegee. If it is OK, clean it up with a squeegee. Some paintball guns should not be cleaned using a squeegee – if this affects your model, you should use either a Q tip or a wet toothbrush to clean out the body carefully. Cleaning out the gun prevents any jamming or damage to the paintball gun. Wipe down the body to make it completely dry.
5. Clean the Frame
Using a Q-tip or a wet toothbrush, clean up the grip frame of the paintball gun. Make sure you do not mess around with the trigger assembly. It’s not easy to put it all back together if you don’t know how to. Focus on the frame itself and dry it up.
6. Clean the Bolt and Hammer
The next step in cleaning a paintball gun is the bolt and the hammer. Use a clean paper towel to give them both a good wipe down. Dry the parts off once you have wiped them properly. The O-rings on both of these parts need to be checked for any signs of damage. A little wear and tear is OK but if there’s extensive damage, you should consider replacing both of them. Take care when moving the bolt slide – do it slowly, to avoid spring damage.
7. Lubricate the Parts
Once it’s all cleaned up, you should give each part a thorough inspection for signs of damage again. If there’s anything too worn out, this is when you replace the part. With everything properly cleaned, you need to lubricate the entire thing carefully. Use a Q-tip to lightly coat the O-rings. Make sure you only use paintball oil recommended by the manufacturer of your model.
8. Reassemble the Gun
The last step in how to clean the paintball gun is to just put it all back together. While it will be pretty easy to put it back together once you have cleaned out the paintball gun a few times, you should reassemble it using the schematic to help you when you go for it the first time. You need to make sure that the order of assembly is correct, and every part is installed properly.
With your gun assembled properly, you can rest assured that you have a marker in excellent working order for a long time. To protect it, keep it in a gun case – this will help prevent dust and debris working its way in when you’re not using it.
It is literally as easy as that. Best of luck and play safe!
