As our Springfree doesn’t get regular use these days, since we only get our Grandchildren a few times a month, I noticed the zipper didn’t zip smoothly. So I remembered getting a zipper lubricant with our yeti cooler a long while ago (I don’t think you get it anymore when you buy one). So I ran the wax lubricant over the teeth – just a little I wanted to make sure it worked and didn’t want to gunk up the teeth with wax. Well low and behold it worked like a charm! I found the company that made the one for yeti on Amazon. I would recommend getting a tube to have it on hand in case your zipper gives you a hard time.
