X-HT-300346

Marine and outdoor zippers are constantly exposed to harsh environments, making them susceptible to damage and corrosion. On your boat, saltwater and salt air can cause metal zipper components to corrode, leading to malfunctioning or stuck zippers. Likewise, zippers found on tents, hiking packs and golf bags can fail and jam from sand, dirt and debris. Fortunately, with the right maintenance, you can prevent this damage and extend the life of your marine and outdoor zippers. Read on to learn the best methods for maintaining, protecting and fixing your zippers.
How to Maintain, Unstick & Protect Marine & Outdoor Zippers

1. Regular Cleaning to Prevent Corrosion

The first line of defense against salt damage is routine cleaning. After each exposure to saltwater, salt air or dirt, rinse your zippers thoroughly with fresh water. Even if your zippers haven’t been in direct contact with debris, rinsing them regularly is a smart preventative measure.

Cleaning Steps:

  • Use an old toothbrush or a small brush to gently scrub the zipper teeth, removing salt, sand and debris.
  • Please make sure all parts of the zipper are clean.
  • Allow zippers to dry completely before folding or storing them to prevent moisture-related corrosion.
  • Even molded tooth zippers, which are more resistant to corrosion, should be cleaned regularly to prevent debris from interfering with their function.

2. Lubricate for Smooth Operation

If your zippers aren’t gliding as smoothly as they used to, applying a zipper lubricant can make a big difference. It’s essential to use products specifically designed for zipper lubrication, as other substances can attract dirt and cause further issues.

Recommended Products:

ZippyCool™ Kit: This two-step system includes a Cleaning Fluid to remove dirt and a Lubricating Stick to keep the zipper teeth moving smoothly. It works on all types of metal, coil and molded tooth zippers.

Pro Tip: Treat zipper lubricant like sunscreen — the more consistently you apply it, the better your zippers will perform over time. Follow the instructions on the product packaging for the best results.

3. How to Fix Corroded or Stuck Zippers

If your zippers are already corroded, you may notice a white film or difficulty moving the slider. Don’t worry — you can still restore functionality with these simple steps.

To Clean Corroded Zippers:

  • Mix white vinegar with boiling fresh water.
  • Use a small brush to scrub the corroded areas of the zipper.
  • Open and close the zipper during cleaning to ensure you reach every surface.
  • After cleaning, apply a protective, zipper-safe lubricant like ZippyCool to keep the zipper functioning smoothly.

To Free a Stuck Zipper:

McLube™ Sailkote: This dry lubricant has a hydrophobic clear coating that bonds to clean, dry surfaces and won’t wash away. It doesn’t attract dirt, water or contaminants, making it perfect for marine and outdoor zippers. To Use: Spray Sailkote on the stuck zipper and move the slider back and forth to distribute the lubricant.

Alternative Method: Use a lip balm or ChapStick. Rub the balm around the zipper teeth and slider, then move the slider to help free it. The wax helps lubricate the zipper, but be cautious — balms can attract debris if applied before heading outdoors.

Important Tips:

  • Avoid using silicone-based lubricants, as they attract dirt and debris.
  • Always clean the zipper thoroughly before applying any lubricant to prevent particles from getting trapped.
