How to Clean Spray Foam Gun

Why Does a Spray Foam Gun Get Dirt

The number one reason that your spray foam gun will get dirty is because of the nature of the product itself. Spray foam is made up of two main ingredients: a polymer and a copolymer. These two materials work together to create the expanding, foamy substance that we know and love.

Over time, these polymers will start to break down and separate. When this happens, the co-polymer will start to clump up and collect in the nozzle of your gun. This can lead to a decrease in performance and an increase in gun cleaning time.

Necessary Materials You Need to Clean Spray Foam Gun:

  1. Rubber gloves
  2. Goggles
  3. A spray bottle
  4. White vinegar
  5. A cleaning brush
  6. A toothpick or other sharp object (optional)

You’ll need these basic materials to clean your foam gun. You may also want to have some rags on hand to help with the cleaning process.

10 Steps on How to Clean Spray Foam Gun

1. Remove the Canister:

The first step is to remove the canister from the gun. This will give you better access to the gun parts that need to be cleaned.

Removing canisters is essential because you do not want to get any water or cleaners inside of them. if any water or cleaner gets in the canister, it could ruin the spray foam. So, be careful while removing the canister, and do not put it back on until all of the parts of the gun have been cleaned.

2. Clean the Nozzle:

The next step is to clean the nozzle. The nozzle is where the spray foam comes out, so it can quickly become clogged with dried-on foam. To clean the nozzle, unscrew it from the gun and soak it in a cup of hot water for about 15 minutes.

3. Clean the Barrel:

The barrel is the part of the gun that holds the canister. Unfortunately, it can also become clogged with dried-on foam, so it’s important to clean it as well. To clean the barrel, unscrew it from the gun and soak it in a cup of hot water for about 15 minutes.

4. Clean the Trigger:

The trigger is another part of the gun that can become clogged with dried-on foam. To clean the trigger, soak it in a cup of hot water for about 15 minutes. Make sure to pull the trigger a few times while it’s soaking to help loosen any dried-on foam.

5. Clean the Screen:

The screen is located at the end of the barrel. It’s there to catch any debris that might be in the canister, and it can become clogged with dried-on foam, just like the other parts of the gun. To clean the screen, soak it in a cup of hot water for about 15 minutes.

6. Clean the O-Ring:

The O-ring is located at the base of the nozzle. It’s there to create a seal between the nozzle and the gun, and it can become clogged with dried-on foam, just like the other parts of the gun. To clean the O-ring, soak it in a cup of hot water for about 15 minutes.

7. Clean the Canister:

Once all of the parts have been soaked and cleaned, it’s time to flush the gun. To do this, attach the barrel to the gun and fill it with hot water. Be careful not to overfill the barrel, as this can cause water to leak out of the gun. If you cram the barrel, you’ll need to start the flushing process over again.

9. Dry the Gun:

Once the gun has been flushed, it’s essential to dry it off. To do this, remove all of the parts from the weapon and allow them to air dry. Once they’re dry, reassemble the gun and test it out to make sure it’s working correctly.
