How to clean your syringe for re-use: Discard any glue left into the trash. Pull out the plunger and air out. Push a paper clip through the syringe tip and one also into the end of the syringe to push out any leftover glue. Helpful hint: The Ninjas only squeeze in 1 ml of glue at a time.. no need to over fill syringes and waste glue.
