Loosening Zipper
When a zipper gets stuck or seems difficult to move, WD-40 can be a handy solution. Simply spray a small amount of WD-40 along the zipper teeth on both sides. Gently wiggle and move the zipper to distribute the lubricant. The WD-40 will help loosen any debris or rust that may be causing the zipper to stick, making it easier to zip and unzip smoothly.
