Should you leave a glue stick in a glue gun?
No, you do not normally need to remove a Bostik Hot Glue Stick from a glue gun after use. Glue sticks are designed to remain in the tool between applications and can be used again the next time the glue gun is heated.
To help prevent feeding issues, use the correct glue stick size and avoid forcing sticks through the mechanism. If a glue stick becomes jammed, allow the glue gun to cool before investigating the blockage.
