How do you remove a stuck glue stick from a glue gun?
If a glue stick becomes stuck in a glue gun, unplug the glue gun and allow it to cool completely before attempting to remove the glue stick.
Do not force the glue stick through the gun. Glue stick jams can occur when an incompatible glue stick is used or when the stick is inserted incorrectly. Always use the recommended glue stick type for your glue gun and follow the product instructions.
