Before starting here is a list of things that you will require to clean your paintball gun.

Step 1: Remove the Air Tank

To prevent any kind of accidental fire, removing the gas tank is the number one priority while cleaning your paintball gun.

Make sure that there is no gas inside the gun to prevent any type of miss fire.

This is the first and most important rule when learning how to clean a paintball gun.

Now, remove your fuel canister and find its ASA lever.

If you have a gun without an ASA lever then you need to consider reading the instruction manual that came with your specific gun about de-linking your gas tank.

Most guns should come with an instruction manual.

Step 2: Disassemble your Paintball Marker

You might require Hex Keys for disassembling your marker.

When you have the hex keys in your hand, start with the hopper. Start dissembling it carefully.

Now, slowly start disassembling the bolt, hammer, barrel and grip frame and set them aside together in order.

Now, take your maintenance kit and let’s start cleaning. If you don’t have a maintenance kit, you can check out one here.

Firstly, check the gun’s manual to ensure it’s ok to use a squeegee to clean the gun.

If it is, go ahead and use a squeege to clean out any paint residue within the barrel of the gun.

A build up of paint residue can  affect the gun’s accuracy and performance during a match, so you want to make sure you clean the barrel gently but thoroughly.

After the squeegee, use warm water and paper to wipe down the barrel.

After that, use a paper towel to clean any remaining water or moisture inside the barrel. Now, set the barrel aside.

Step 4: Clean the Body of the gun

Again, check the instructions to ensure a squeegee is allowed.

If it is, you can go ahead and use it to clean the body of the gun, in a similar way as the barrel.

After using the squeegee, grab a toothbrush.

Dip it into warm water, and start scrubbing the gun.

This is to help you clean any hard reaching part of the gun that the squeegee might have missed.

Do not try to disassemble any part of the trigger. It will be extremely complicated to reassemble it again.

Once you have cleaned every part of the body, take a paper towel and use it over your gun to make sure that your marker is completely dry.
