How to Unstick a Zipper on a Jansport Backpack

Having a zipper stuck on your Jansport backpack can be frustrating, especially in a hurry. A stuck zipper can prevent you from accessing the contents of your bag, leaving you feeling helpless. However, with a few simple steps and the right tools, you can easily unstick the zipper and get your Jansport backpack back to full functionality. In this article, we will guide you through unsticking a zipper on a Jansport backpack.

How to Unstick a Zipper on a Jansport Backpack

Before we delve into unsticking a zipper, it’s essential to understand how zippers work and the different types of zippers available.

How Zippers Work

Zippers consist of two strips of fabric with interlocking metal or plastic teeth that can be opened or closed by a slider. The slider moves up and down, aligning the teeth to connect or separate the two fabric strips. When a zipper gets stuck, the teeth are not properly aligned, making it difficult to move the slider.

Types of Zippers

There are various types of zippers, including coil zippers, plastic-molded zippers, and metal zippers. Jansport backpacks typically feature coil zippers, which are lightweight and flexible. These zippers are prone to getting stuck due to debris or misalignment.

Common Issues with Zippers

Before attempting to unstick a zipper, it’s important to identify the specific issue you’re facing. The two most common zipper issues are a stuck zipper and a broken zipper slider.

Zipper Stuck

A stuck zipper is the most common problem encountered. It can occur due to fabric caught in the teeth, debris or dirt buildup, or misalignment of the zipper teeth.

Zipper Slider Broken

In some cases, the zipper slider itself may be broken or damaged. This can prevent the zipper from moving smoothly, making it difficult to open or close the backpack.

Tools Required for Unsticking

To successfully unstick a zipper on your Jansport backpack, you will need some tools to help resolve the issue. These tools include:

  • Tweezers: Used to remove any fabric or debris stuck in the zipper teeth.
  • Lubricant: Such as graphite powder or silicone spray, lubricate the zipper and reduce friction.
  • Pliers: Used to manipulate the zipper teeth if necessary gently.

Step-by-Step Guide

Follow these step-by-step instructions to unstick the zipper on your Jansport backpack:

1. Preparing the Backpack

Start by emptying the contents of your backpack. This will give you better access to the zipper and reduce the risk of damaging any items inside.

2. Applying Lubrication

Using tweezers, carefully remove any fabric or debris stuck in the zipper teeth. Then, apply a small amount of lubricant to the zipper teeth. Graphite powder or silicone spray works well for this purpose.

3. Manipulating the Zipper

Gently move the zipper slider up and down, applying gentle pressure. The lubricant should help loosen any stuck or misaligned teeth. If necessary, use pliers to manipulate the teeth back into alignment. Be careful not to apply too much force, which can damage the zipper.

Preventing Zipper Sticking

To avoid future zipper-sticking issues with your Jansport backpack, consider the following preventive measures:

  • Regularly clean the zipper area to remove dirt and debris.
  • Avoid overstuffing the backpack, as this can strain the zipper.
  • Use a zipper wax or lubricant periodically to keep the zipper moving smoothly.


Unsticking a zipper on your Jansport backpack doesn’t have to be daunting. With the right tools and a little patience, you can quickly resolve the issue and restore the functionality of your backpack’s zipper. Remember to be gentle and take preventive measures to avoid future sticking problems. Now you can confidently unstick your Jansport backpack zipper whenever needed.

FAQs – How to Unstick a Zipper on a Jansport Backpack

1. Can I use WD-40 to unstick the zipper on my Jansport backpack?

While WD-40 is a common lubricant, it’s not recommended for zipper use. WD-40 can leave behind residue that attracts more dirt and debris, further exacerbating the sticking issue. Using graphite powder or silicone spray specifically designed for lubricating zippers is best.

2. Can I use soap or water to unstick the zipper?

Using soap or water can temporarily alleviate a minor sticking issue, but it’s not a long-term solution. Moisture can eventually lead to rust or corrosion on the zipper, worsening the problem. Using a dry lubricant like graphite powder or silicone spray is better.

3. What should I do if the zipper slider is broken on my Jansport backpack?

If the zipper slider is broken, you may need to replace it. Contact the manufacturer or a professional repair service to obtain a replacement slider or get advice on repairing the zipper.

4. How often should I clean the zipper on my Jansport backpack?

It’s a good practice to clean the zipper area of your Jansport backpack regularly, especially if you frequently use it in dusty or dirty environments. Aim to clean it at least once every few months or more often if you notice any debris accumulation.

5. Can I use a candle as a lubricant for my Jansport backpack zipper?

Using a candle as a lubricant is not recommended for zippers. The wax from the candle can leave a sticky residue on the zipper, which can attract dirt and debris, causing further sticking issues. It’s best to use a dry lubricant like graphite powder or silicone spray specifically designed for zippers.
