The YKK Zippy Cool system combines a cleaning fluid and lubrication stick to keep outdoor zippers running smoothly season after season. The cleaner dissolves salt, dirt, and residue that cause sticking, while the lubricant creates a protective barrier against corrosion and wear. Perfect for cushions, covers, tents, and marine gear, it extends zipper life and prevents costly replacements. Pair it with our full range of DIY trims, fasteners, and embellishments to keep every detail of your fabric project performing like new.
