The epoxy mixing nozzles are not designed to be reused indefinitely. The mixing chambers inside the nozzle can become worn and compromised over time, leading to inaccurate mixing and potential failure of the bond.

However, in some cases, it is possible to clean epoxy mixing nozzles to extend their lifespan and reuse them a few times before they need to be replaced. The cleaning process outlined in the article can dissolve any cured epoxy inside the mixing chamber and restore the nozzle to a functional state.

Cleaning epoxy mixing nozzles is essential to prolong their lifespan and ensure that they work effectively.

The following steps outline how to clean epoxy mixing nozzles:

  • Step 1:

    Remove the used nozzle from the epoxy cartridge.

  • Step 2:

    Cut off the end of the nozzle using a pair of scissors or a craft knife. This will expose the mixing chamber inside the nozzle.

  • Step 3:

    Place the cut nozzle into a container of acetone or another suitable solvent. The solvent should completely cover the mixing chamber.

  • Step 4:

    Allow the nozzle to soak in the solvent for at least 30 minutes. This will dissolve the cured epoxy inside the mixing chamber.

  • Step 5:

    Once the epoxy has dissolved, remove the nozzle from the solvent and rinse it thoroughly with warm water. This will remove any remaining epoxy and solvent from the nozzle.

  • Step 6:

    Leave the nozzle to air dry before reusing it.


It is important to note that epoxy mixing nozzles should not be reused indefinitely. The mixing chambers will eventually become worn, and the nozzles will need to be replaced. However, by cleaning your mixing nozzles regularly, you can extend their lifespan and save money in the long run.

Furthermore, it’s essential to wear personal protective equipment, such as gloves and safety glasses, when working with epoxy resins and solvents. Always work in a well-ventilated area and follow the manufacturer’s instructions for use and disposal.


In conclusion, cleaning epoxy mixing nozzles is a simple process that can save you money and ensure that your epoxy resins are mixed correctly. By following the steps outlined in this article, you can effectively clean your mixing nozzles and prolong their lifespan.
