How to Get a Zipper Unstuck on a Jansport Backpack

Anyone who has ever used a Jansport backpack knows the frustration of a stuck zipper. Zipper teeth can become caught on the fabric of the bag or on the zipper puller, making it impossible to move the zipper up or down. When this happens, it can seem like the zipper completely refuses to budge no matter what you do. But there are a few simple tricks that can help get stuck zippers unstuck.

Before we discuss how to get a zipper unstuck on a Jansport backpack, let’s find out what causes it in the first place.

What Causes a Zipper to Get Stuck

Most zippers have two main components, the teeth, and the slider. The teeth are the interlocking metal or plastic pieces that run along either side of the zipper, while the zipper slider is the piece that opens and closes the gap between the teeth. Usually, when a zipper gets stuck, it’s because either the teeth are worn down, they’ve become bent or broken.

Worn Down

Zippers can get stuck for a variety of reasons. The most common reason is that the zipper pull has come detached from the zipper itself. This can happen if the zipper is old and worn or if it was not installed properly in the first place.

Zipper Is Too Long

If the zipper is too long, there’s a chance it might not close all the way. In other words, if you want this garment to actually zip up, make sure the zipper length is appropriate. The zipper has been pulled out.

Snagged Fabric

Sometimes, the zipper is stuck because there is fabric caught in it. If the surrounding fabric is wrinkled, it can make it difficult for the slider to move up and down the zipper. Hoodies, Sweatshirts, Jeans, Lingerie, and everything that comes with zippers can get caught in the teeth. Inspect the area surrounding the zipper to see if there is any fabric that might be caught, and gently remove it.

A stuck zipper can be incredibly frustrating, especially when you’re in a hurry to get out the door. There are a few different types of zippers, and each has its own specific function. The good news is that there are a few simple tricks you can use to get your zipper unstuck.

Pencil Method

Pencils are made from Graphite and are known as a natural dry lubricant,

Step 1: Rubbing Pencil

Rub the graphite pencil over both holes in the tooth. Keep rubbing with the tip of the pencil and you should be able to see a trace of enough graphite behind it. Then focus where the lines intersect because that’s usually where jams happen!

Step 2: Apply Gentle Force

Lubricant Method

One of the easiest way to unstuck a zipper is to use a lubricant. This can be anything from Vaseline, olive oil, or lip balm to WD-40 or even cooking oil.

Use a cottonswab or brush to apply lubricant on the zipper teeth, apply a generous amount.
