 1、 What if the zipper is stuck and the clothes can't be pulled
 Zipper is a common thing in our life. It is often used in clothes, bags, etc. It not only plays an ending role, but also has a certain decorative role. But sometimes when I put on my clothes and zip up, I find it doesn't move. At this time, you should use the correct method.
 1. First, we should hold the tail of the zipper with one hand, straighten the zipper, and then pull up the zipper head. If it is smooth, it is likely that the zipper is bent. If it is not smooth, it may be stuck. You can check whether there is any foreign matter or the cloth card beside the clothes has entered. Take out the foreign matter and take out the cloth.
 2. The zipper is stuck and cannot be pulled. It is likely that the zipper has been used for a long time, rusted or worn. You can use a candle to wipe the zipper surface back and forth, and then repeatedly pull it up and down several times. The candle has good lubrication effect and can make the zipper slide more smoothly.
 3. You can also apply some lubricating oil on the zipper, just like the candle, mainly for smoothness and better pulling. If the zipper cannot be pulled due to damage, the zipper shall be replaced in time to avoid affecting normal use.
