How can I fix a stuck zipper?
assistant
Start by making sure the zipper is all the way up. Then, move the slider back and forth gently to see if the zipper will move. If it does, continue sliding it up and down until it opens and closes properly. If the slider is still stuck, try applying some lubricant to the teeth on the zipper, such as regular lip balm, petroleum jelly, or a lubricant specifically designed for zippers. You can also try slightly loosening the zipper teeth. Hold the top of the zipper, then pull the bottom away from the teeth to give it more space. Lastly, if all else fails, you can insert a small needle or pin into the zipper's teeth to gently pull the zipper apart.
