How to free a stuck zip

Short answer: Find out what is caught, pull the zip back rather than forward, and lubricate the teeth with a pencil or a little soap. Pulling harder risks tearing the fabric. Take it calmly, and the zip usually comes free.

Stop before you pull harder

When a zip sticks, it is tempting to yank it harder. Do not. Hard pulling tears the fabric instead of freeing it, and a damaged zip is much harder to save than one that is simply caught. Take a deep breath and work out what is actually holding it.

First see what it is

In nine cases out of ten, a thread or a piece of fabric has got in between the teeth. Look from both sides in good light before you pull harder. You can often see a small tab of fabric or a loose thread caught right at the slider, where the teeth meet.

How to free the fabric

Hold the fabric with one hand and slowly pull the zip back towards the starting point with the other. Do not twist. When you back the zip up, the teeth let go of whatever is caught, and the fabric can come free. Do it in small tugs and feel whether it starts to give. See our bamboo jogging suit for men.

When the thread is stuck

If it will not come out, cut the thread with small scissors. Cut close to the teeth and avoid cutting the fabric itself. Once the thread is divided, you can pull the two ends out separately, and the zip comes free. Use tweezers if the ends are hard to grip.

When it just runs stiffly

Run a soft pencil over the teeth on both sides, or rub with a piece of dry soap. The graphite and the soap work as a lubricant. Let the zip run back and forth a few times so the lubricant spreads along all the teeth. Wipe off any excess with a damp cloth so it leaves no marks.

Why pencil and soap work

The graphite in a pencil and soap make the teeth smoother, so the slider can glide without catching. It is a simple method and gentle on the fabric. Apply only a little, because a thin film is enough, and add more only if the zip still runs stiffly. See our bamboo hoodie for men and bamboo hoodies for women.

Do not use oil

Avoid oil, because oil stains the fabric, and the stain can be hard to remove. Pencil or soap is better because they leave no greasy marks. If you are unsure, try first at the end of the zip where nobody sees it. Then you know whether the fabric tolerates the product before you use it all the way.

When the teeth are bent

If teeth are bent, you can straighten them carefully with pliers. Press lightly and go step by step so you do not snap them. If a tooth is missing, the zip cannot be repaired this way, and it must be replaced. Also check that no teeth sit loose in the fabric.

When it opens again afterwards

If the zip opens again by itself, the slider is worn. Squeeze it very lightly with pliers so it grips the teeth better. Squeeze gently, because too much pressure can break the slider. If that does not help, it is time to replace the zip. Take it to a tailor if you like.

Frequently asked questions

Can you use oil

No, oil stains the fabric. Pencil or soap is better because they leave no greasy marks. Try first in a spot where nobody sees it if you are unsure how the fabric reacts.

What if the teeth are bent

Straighten them carefully with pliers. If a tooth is missing, the zip must be replaced. Go calmly and press lightly, so you do not snap more teeth while you straighten them.
