Should you remove a Glue Stick from a glue gun?
No, it is generally recommended to leave a partially used Glue Stick inside the glue gun. Removing it may put unnecessary strain on the feeding mechanism and could affect how the tool operates.
If excess Glue Stick extends from the back of the gun, it can be trimmed carefully. Once the remaining Glue Stick becomes too short to feed properly, simply insert a new Glue Stick and continue using the glue gun as normal.
