How to Clean Ender 3 (Pro/V2) Nozzle

An Ender 3 (Pro/V2) is a fantastic 3D printer for creating your own unique designs. Like all machinery, proper maintenance is necessary to keep your printer functioning at its best. One of the critical components of an Ender 3 (Pro/V2) is the nozzle. Over time, the nozzle can become clogged, which can lead to improper printing results. For this reason, it’s essential to learn how to clean an Ender 3 (Pro/V2) nozzle properly.

In this post, we’ll walk you through the steps to clean your printer’s nozzle to ensure that it remains functioning correctly.

Step 1: Heat Your Printer

The first step in cleaning an Ender 3 (Pro/V2) nozzle is to heat your printer to the optimal temperature. You can usually check the recommended temperature in your printer’s manual or online. Once your printer has reached the perfect temperature, then turn it off.

Step 2: Remove the Nozzle

The next step is to remove the nozzle gently. You can use a wrench to make it easier. Remember to wear gloves to avoid burning your fingers. Turn the nozzle in a counterclockwise direction to loosen it. Once the nozzle has been detached, you can set it carefully aside. Avoid losing any nozzle components, such as a heating block or a bowden tube.

Step 3: Clean the Nozzle

Now it’s time to clean the nozzle. You can use a brass wire brush to remove any gunk or debris that may have accumulated inside the nozzle. Don’t use any metal tools to clean the nozzle as they can scratch the brass surface and impact the printing quality negatively. Once you’re sure that there’s no residual blockage or debris, submerge the nozzle in acetone for around an hour. This process will clear any plastic residue that may be inside the nozzle. After that, wash the nozzle with water and let it dry.

Step 4: Re-Place the Nozzle

After cleaning and drying the nozzle, it’s time to install it back into your 3D printer. Ensure that all components are tightened and secure with a wrench and your gloved hand. Be sure to test print something basic initially to assure the clean nozzle is still working well.

Step 5: Maintain Regular Cleanings

It’s essential to maintain regular cleanings of your Ender 3 (Pro/V2) nozzle. By doing so, you’ll prevent any blockages or clogs from occurring, significantly extending the life of your printer. Plan a cleaning schedule of your machine to avoid missing a session and to guarantee its performance.


Proper maintenance of your Ender 3 (Pro/V2) nozzle is critical to its longevity and printing quality. It’s essential to follow the steps above to clean your printer’s nozzle regularly. So, always ensure that before cleaning, you have shut off and let the printer cool down, have removed your nozzle safely and carefully, and utilize proper cleaning tools and materials.

With regular cleaning, you’ll avoid productivity issues and enjoy continued usage of your 3D printer for a much longer period.
