Yes, we're talking about maintaining that little piece of metal and the accompanying teeth. A zipper is one of those items that's frequently taken for granted until it fails to do its job properly. Zip Care's push-pull brush top enables the cleaner to be delivered between the teeth and physically removes foreign debris that can jam the zipper, while leaving behind a mild lubricant containing no silicone. The new and improved formula is thicker, perfect for use on all types of zippers, nylon or metal, especially those on wet suits, dry suits, waterproof bags, gear bags, tents, packs, sleeping bags and outdoor clothing. 2oz.
