How To Restore Dwr On Gore Tex

Gore-Tex is renowned for its exceptional waterproof and breathable qualities, making it a popular choice for outdoor gear, jackets, and footwear. Over time, however, the durable water repellent (DWR) coating on Gore-Tex fabrics can wear off due to regular use, washing, and exposure to the elements. When this happens, your waterproof gear may start to leak or become less effective at repelling water. Fortunately, restoring the DWR coating is a straightforward process that can significantly extend the life and performance of your Gore-Tex apparel or footwear. In this comprehensive guide, we will walk you through the steps to effectively restore DWR on Gore-Tex, ensuring your gear stays dry, breathable, and in top condition for your outdoor adventures.

Understanding DWR and Its Importance

Durable Water Repellent (DWR) is a special coating applied to the outer fabric of Gore-Tex and similar waterproof materials. Its purpose is to cause water to bead up and roll off the surface, preventing saturation and maintaining breathability. When the DWR layer starts to wear or becomes contaminated with dirt, oil, or detergent residues, the fabric no longer sheds water efficiently. This can lead to dampness inside the garment, reduced breathability, and decreased overall performance.

Restoring the DWR is essential to keep your gear functioning as intended. It’s a simple process that involves cleaning the fabric thoroughly and then applying a new DWR coating. Doing so not only improves water repellency but also prolongs the lifespan of your Gore-Tex products.

Signs That Your Gore-Tex Needs DWR Restoration

• Water soaking in: Water no longer beads and instead soaks into the fabric during rain or outdoor activity.
• Reduced breathability: Feeling damp or clammy inside the garment even during light activity.
• Persistent dampness: The outside of the jacket or gear remains wet for extended periods after exposure to moisture.
• Visible water stains or spots: Water no longer rolls off smoothly, leaving spots or streaks.
• Frequent washing: After multiple washes, the DWR may diminish, indicating it’s time for reapplication.

Preparing Your Gore-Tex Gear for DWR Restoration

Before applying a new DWR coating, proper preparation of your gear is crucial. Follow these steps to ensure optimal results:

• Clean thoroughly: Remove dirt, oils, and residues that can impair the DWR application. Use a specialized cleaner designed for waterproof fabrics or a gentle detergent free of fabric softeners.
• Avoid fabric softeners and bleach: These can damage the waterproof membrane and reduce breathability.
• Perform a cold or warm wash: Follow the manufacturer’s instructions, typically washing on a gentle cycle with warm water.
• Rinse well: Ensure all detergent residues are rinsed out completely.
• Dry properly: Air drying is preferred, or tumble dry on a low setting if the manufacturer permits. Heat helps activate the DWR coating.

Choosing the Right DWR Restoring Product

Not all DWR treatments are created equal. When selecting a product to restore the water repellency of your Gore-Tex gear, consider the following:

• Compatibility: Use a DWR spray or wash-in treatment specifically formulated for waterproof/breathable fabrics.
• Brand reputation: Opt for trusted brands such as Nikwax, Grangers, or Gear Aid, which are known for quality and effectiveness.
• Type of application: Decide whether you want a spray-on or wash-in product. Spray-on treatments are convenient for spot treatments, while wash-in products provide more thorough coverage.
• Environmental considerations: Choose eco-friendly options if possible, as they are safer for the environment and your gear.

Applying DWR Treatment to Gore-Tex

Once your gear is clean and dry, you can proceed with applying the DWR treatment. Follow these steps carefully to ensure the best results:

Applying Spray-On DWR

1. Lay your gear flat on a clean, dry surface.
2. Hold the spray nozzle about 6-12 inches from the fabric.
3. Spray evenly over the entire outer surface, paying special attention to seams and high-wear areas.
4. Ensure thorough coverage without oversaturating any one spot.
5. Allow the treated gear to air dry, or follow the product’s instructions regarding heat activation.
6. For best results, you may want to lightly tumble dry on a low heat setting if the manufacturer recommends it. This helps to bond the DWR coating to the fabric.

Applying Wash-In DWR

1. Pour the recommended amount of DWR wash-in product into a washing machine filled with warm water.
2. Add your clean, dry Gore-Tex gear to the wash cycle.
3. Run a gentle cycle, ensuring the entire garment is soaked with the treatment.
4. After washing, run an extra rinse cycle to remove any excess treatment.
5. Dry the gear as per the manufacturer’s instructions, often involving tumble drying on low heat to activate the DWR.

Always read and follow the specific instructions provided on the DWR treatment product for optimal application and safety.

Post-Treatment Care and Maintenance

Restoring DWR is not a one-time fix; maintaining it requires ongoing care. Here are some tips to keep your Gore-Tex gear performing well:

• Regular cleaning: Clean your gear after exposure to dirt, mud, or salt to prevent contamination of the DWR coating.
• Periodic reapplication: Depending on use, reapply DWR treatments every few months or after several washes to maintain water repellency.
• Proper storage: Store gear in a cool, dry place away from direct sunlight to prolong the DWR’s effectiveness.
• Avoid harsh detergents: Use specialized cleaners designed for waterproof fabrics to prevent stripping away the DWR.
• Gentle drying: When drying, avoid high heat or direct sunlight, which can degrade the fabric and DWR coating.

Additional Tips for Effective DWR Restoration

• Test first: Before treating your entire garment, test the product on a small, inconspicuous area to ensure compatibility.
• Work in a well-ventilated area: Many DWR treatments contain chemicals that should be used in open, ventilated spaces.
• Follow manufacturer instructions: Always adhere to the specific guidelines for each product to avoid damage.
• Use heat wisely: Applying gentle heat through tumble drying or ironing (if permitted) can help activate the DWR coating, but avoid excessive heat.

Conclusion

Restoring the DWR on your Gore-Tex gear is a simple, cost-effective way to enhance its waterproofing and breathability. By understanding the importance of DWR, recognizing when it needs replenishing, and following proper cleaning and application procedures, you can ensure your outdoor gear remains in peak condition. Regular maintenance and reapplication of DWR treatments will extend the lifespan of your Gore-Tex products, keeping you dry and comfortable during all your outdoor adventures. With these easy steps, you can enjoy the full benefits of your waterproof gear season after season, no matter the weather conditions.
