A zipper is one of the most used parts on an RTIC cooler, which allows easy access inside the cooler. However, like any other mechanical part, zippers can jam or break over time due to wear and tear. A stuck zipper not only hampers access but also allows cold air to escape, affecting the cooler’s ability to retain ice.
Lubricating the zipper is an easy DIY fix to keep it gliding smoothly for years. This comprehensive guide covers everything you need to know about lubricating RTIC cooler zippers.

Why Should You Lubricate the RTIC Cooler Zipper?
Here are some key reasons why lubricating the zipper is recommended:
- Prevents zipper from jamming or breaking by reducing friction
- Allows smooth gliding of the zipper teeth
- Protects the zipper material from wear and tear
- Minimizes dirt buildup on the zipper teeth
- Maintains airtight seal to maximize ice retention
- Prolongs life of the zipper
- Prevents zipper damage during opening/closing
- Restores smooth functioning of an old stiff zipper
Regular lubrication after every few uses ensures the zipper remains functional for many years. Neglecting this can make it prone to damage and ruin its water-resistant sealing ability.
When to Lubricate the Zipper?
The frequency of lubricating the zipper depends on usage:
- For frequent users: Lubricate every 1-2 months
- For moderate users: Lubricate every 4-6 months
- For occasional users: Lubricate once a year
Apart from regular lubrication, also do it whenever you notice:
- Zipper not gliding smoothly
- Increased effort needed to open/close
- Zipper making screeching noises
- Broken zipper teeth
- Difficulty maintaining the seal
Catching zipper issues early and lubricating it can prevent more expensive repairs or replacement later.
What You’ll Need
Lubricating the zipper is easy and requires just a few supplies:
- Lubricant – Zipper wax sticks, paraffin wax, beeswax, bar soap
- Clean cloth – For cleaning the zipper
- Brush – Small toothbrush or groove brush
- Mini screwdriver – For fixing any broken zipper teeth
You probably have most of these items readily available at home. Ensure the cloth is lint-free to avoid leaving residue on the zipper. Avoid oils or greases that can damage the zipper material.
How to Lubricate RTIC Cooler Zipper
Follow these simple step-by-step instructions to properly lubricate your RTIC cooler zipper:
Step 1: Open the Zipper Fully
The zipper needs to be fully extended to properly reach all the teeth while lubricating. Open it all the way and keep it unlocked in the open position.
Step 2: Clean the Zipper
Use a clean dry cloth to wipe down the zipper rails on both sides carefully. This removes any dirt, grime, or old lubricant residue buildup.
Make sure to reach the corners properly. For stubborn deposits, use mild soap and water followed by drying with a cloth.
Step 3: Apply Lubricant
Take a zipper wax stick, bar soap, or paraffin/beeswax. Rub it along the length of the zipper teeth on both sides. Apply a thin uniform coat and let the lubricant penetrate in between the teeth.
It helps to use an old toothbrush or a groove brush to smear it evenly and get it deep inside the zipper grooves.
Step 4: Close and Open the Zipper
Once sufficiently lubricated, move the zipper slider across the full length a few times. This evenly spreads the lubricant over all the teeth surfaces.
Zip it close and open a few more times to allow the lubricant coating to transfer through the moving components.
Step 5: Remove Excess Lubricant
After moving the zipper multiple times, wipe off any excess lubricant built up near the ends or edges with a clean dry cloth. This prevents dirt from sticking.
Step 6: Check Zipper Functioning
The zipper should now glide smoothly with minimal effort. Open and close it fully to check for any remaining stiff spots and re-lubricate if needed.
If some teeth are still stuck, use a mini screwdriver to gently pry them loose and realign. Don’t force the zipper if teeth are damaged.
Step 7: Make it Water-Repellent (Optional)
For extra water repellency, rub a bar of soap on the zipper rails. This adds a water-resistant coating to maintain the seal.
Use mild soap that does not have strong fragrance or color additives. Let the soap dry completely before closing the zipper.
Following this simple lubrication process periodically will maximize the zipper lifespan and performance. Just a few minutes of maintenance prevents expensive zipper replacement down the road.
Tips for Proper Zipper Care
Here are some additional pointers to keep your RTIC cooler zipper in the best condition:
- Keep zipper free of grit, salt, and sand that can abrade the teeth
- Don’t force the zipper if it snags to avoid damage
- Store cooler with the zipper slightly open to prevent creasing
- Protect zipper from direct sun exposure and chemicals
- Clean with only mild detergent and avoid bleach/harsh cleaners
- Check for Missing/worn out zipper pulls and replace promptly
- Use only lubricants approved for plastics to avoid cracks
- Replace severely damaged or corroded zippers
A well-maintained zipper improves the cooler’s performance and longevity.
Frequently Asked Questions
How often should I lubricate the zipper?
Lubricate every 1-2 months for frequent use, 4-6 months for moderate use, and annually for occasional use. Also lubricate whenever zipper feels stiff.
What household items can be used as DIY zipper lubricants?
Commonly used homemade lubricants are beeswax, paraffin wax, bar soap, crayon bits, lip balm, and grease pencil. Avoid oils and petroleum jellies that deteriorate plastic.
Can I use WD40 or silicone spray to lubricate the cooler zipper?
WD40 and silicone sprays work for metal zippers but should be avoided for plastic zippers as they can damage the material and finish. Stick to wax or soap lubricants.
How do I fix a sticky zipper that doesn’t close fully?
Sticky zippers need cleaning before lubricating. Check for any obstructions in the teeth. Pry open stuck portions gently with a flat screwdriver and lubricate thoroughly. Replace if too damaged.
Why does the zipper make loud squeaky noises after lubricating?
The squeaking is due to excess lubricant building up. Wipe away any extra lubricant on the outer rails with a dry cloth. The noise should stop after the lubricant spreads evenly after a few uses.
Should I lubricate both sides of the cooler zipper?
Yes, to work properly, the zipper needs to be lubricated on both the inside and outside rails for the slider to move smoothly across the full length.
Conclusion
Lubricating the zipper is essential maintenance to keep your RTIC cooler working flawlessly for many years. This prevents premature wear, damage, and replacements. Follow the easy DIY steps using household items to lubricate periodically. With minimal effort, you can restore smooth zipper function and maintain optimal cooler performance.
