• Missing teeth?

Knowing the exact issue is the first step to the right fix.

Fixing a Stuck Zipper: A Simple Backpack Zipper Stuck Solution

A stuck zipper is usually the easiest problem to solve. Often, the issue is not with the zipper itself but with something caught in its teeth or a lack of lubrication. The first step is to carefully inspect the zipper. Look for any fabric, threads, or debris that might be jammed. Use tweezers to gently pull out any obstructions. Once the track is clear, you can add a little bit of lubrication.

This often happens when fabric or debris gets caught.

• Don’t force it! You might break the teeth.
• Clear the jam: Use a pair of tweezers to gently pull out any trapped cloth, thread, or dirt.

• Gently wiggle: Hold the fabric on both sides taut and gently work the slider back and forth until it moves freely.

• Gently squeeze the top and bottom of the slider to tighten the gap. Be careful not to crush it.
• Test the zipper. This usually solves the problem instantly!
