Chapstik (or a similar lip balm) can be used to lubricate zippers to operate smoothly. I just could not find the 3-in-1 oil so I thought of this. Any petroleum jelly based lip balm will work fine. I used a knock off brand lib balm.

No matter how well a lip balm works, a spray lubricant like WD-40 works much better. A week later the zipper froze again and this time I used a spray lubricant instead for comparison. Stick with a spray lubricant and only use lip balm in an emergency.
