Empty your Syringe by plunging

Firstly, when cleaning your syringe start by emptying it. To do this, push the plunger into in the barrel, it will eject almost all of the resin out and make cleaning it a lot easier. Set the resin aside to dry before discarding it.

Next, take wipe away excess resin while still wet with a paper towel and then eject the epoxy onto a sheet of parchment or wax paper and let it harden before discarding it.

Fill up the barrel with solvent.

To do this, replace the plunger and draw in a solvent solution through the needle, such as isopropyl alcohol, acetone, or distilled white vinegar by pulling the plunger back to draw in liquid until the barrel is full.

Allow the resin stand in the syringe for about 30 – 45 seconds, while giving it a light shake, this will help loosen the resin. Some syringes do not have removable plungers while some are too small to clean inside. Ensure that only the inner part of the barrel and needle are exposed to the solvent, to preserve its lifespan.


Expel the solvent and resin

Push the plunger in, to empty the barrel of solvent and epoxy resin. Expel the solvent by pressing the plunger quickly to apply enough pressure and discard them appropriately based on the type of solvent. Repeat the process above at least twice for better results. Use fresh, unused solvent each time to ensure any remaining epoxy will be properly dissolved, shake and flush before you rinse the syringe out.

With the needle, draw in hot, soapy water to rinse the solvent. Shake to swish the water around and collect any left solvent or resin residue. Eject your used water through the needle and repeat twice or more with fresh water each time to thoroughly clean it.

Next, Use plain clean water for your final rinse to remove soap residue and all traces of solvent as prolonged exposure can damage the syringe.


Unclog the needle

Use a solvent or cleaning wire to remove dried resin from the needle or flush the needle with solvent. You may have to remove the plunger and pour solvent into the barrel from the other end.


Air dry the syringe

Allow the syringe to air dry thoroughly before you use it again. Preferably dislodge the components of your syringe and lay them individually on a clean cloth to dry faster.
