When you’re trapped in a stuck zipper, Windex can save the day. First, test a hidden part of the fabric to make sure it won’t be damaged by the Windex. Then soak the zipper and slowly, slowly pull it to unzip. Go a little bit each time, resoak, and gently keep pulling. Be sure to keep the fabric from bunching into the zipper mechanism. No Windex handy? You can use pencil graphite, lip balm, Vaseline or bar soap to lubricate the stubborn mechanism. See a quick how-to video at http://youtu.be/seDQuPlKi9I
