When your once-reliable waterproof jacket starts letting in moisture, it can be frustrating. Instead of replacing it, you can often restore waterproof clothing to its former glory with a few simple steps. Understanding how to restore waterproof clothing not only saves you money but also extends the lifespan of your valuable outdoor gear, keeping you dry and comfortable during all your adventures.
Understanding Why Waterproof Clothing Fails
Before you can effectively restore waterproof clothing, it is helpful to understand why it stops working. Most waterproof clothing relies on two key components: a waterproof membrane (like Gore-Tex or eVent) and a Durable Water Repellent (DWR) finish on the fabric’s exterior.
The DWR causes water to bead up and roll off, preventing the outer fabric from becoming saturated. Over time, dirt, oils, sweat, and repeated washing can degrade this DWR layer, causing the fabric to ‘wet out’. While the membrane still blocks water, a wet outer fabric can feel clammy and reduce breathability, making you feel cold and damp.
Signs Your Waterproofing Needs Restoration
Identifying when your gear needs attention is the first step in how to restore waterproof clothing. Pay close attention to these common indicators:
Wetting Out: Water no longer beads up and rolls off the fabric surface. Instead, it soaks into the outer layer, making it look dark and heavy.
Dampness Inside: You feel damp even when it is not raining heavily, suggesting moisture is penetrating the fabric.
Reduced Breathability: The garment feels clammy or less comfortable than usual, as the wet outer fabric hinders the membrane’s ability to transfer moisture vapor.
Essential Supplies for Waterproof Clothing Restoration
To successfully restore waterproof clothing, you will need a few specialized products. Using the correct cleaners and treatments is crucial to avoid damaging the delicate waterproof membranes and DWR coatings.
Technical Fabric Wash: A DWR-safe, non-detergent cleaner specifically designed for waterproof breathable fabrics. Brands like Nikwax Tech Wash or Grangers Performance Wash are excellent choices.
Durable Water Repellent (DWR) Treatment: This can be a wash-in solution or a spray-on application. Popular options include Nikwax TX.Direct or Grangers Performance Repel.
Clean Cloths or Sponges: For spot cleaning.
Washing Machine: Ensure it is free of detergent residues.
Tumble Dryer (Optional): For heat activation of some DWR treatments.
Step-by-Step: Cleaning Your Waterproof Clothing
Cleaning is arguably the most critical step in how to restore waterproof clothing. Dirt, oils, and residues from regular detergents can block the DWR and prevent new treatments from bonding effectively.
Prepare Your Garment
Before washing, make sure to empty all pockets, close all zippers and hook-and-loop fasteners, and loosen any drawcords. Inspect the garment for any heavily soiled areas.
Pre-Treat Stains
For stubborn dirt or greasy spots, gently pre-treat with a small amount of technical fabric wash using a soft brush or sponge. Work the cleaner into the stain and let it sit for a few minutes before washing.
Machine Washing
First, clean your washing machine’s detergent dispenser to remove any residual regular detergent. Add your waterproof garment to the machine. Use the recommended amount of technical fabric wash according to the product instructions. Select a gentle cycle (e.g., delicates or synthetics) with cold or warm water. Avoid hot water, as it can potentially damage the membrane.
Rinse Thoroughly
After the wash cycle, run an extra rinse cycle to ensure all soap residues are completely removed. This is vital for the DWR treatment to adhere properly.
Reactivating Existing DWR (Heat Treatment)
Sometimes, the DWR coating on your garment is still present but just needs to be reactivated. This simple step can often restore waterproof clothing’s performance without needing a new DWR application.
Many DWR finishes are heat-activated. After washing, you can place the garment in a tumble dryer on a low to medium heat setting for 20-30 minutes. Always check the garment’s care label first to ensure it is safe for tumble drying. Alternatively, you can gently iron the dry garment on a low, synthetic setting, placing a towel between the iron and the fabric.
Applying New DWR Treatment
If heat reactivation does not work, or if your garment has lost its DWR entirely, you will need to apply a new DWR treatment. This is the core process of how to restore waterproof clothing effectively.
Wash-In DWR Treatments
Wash-in treatments are convenient as they are applied in the washing machine. After the cleaning cycle (and without drying the garment), add the recommended amount of wash-in DWR treatment to your machine’s dispenser. Run another gentle cycle according to the product instructions. This method ensures an even coating over the entire fabric.
Spray-On DWR Treatments
Spray-on treatments offer more targeted application, which is ideal if only certain areas (like shoulders or elbows) are wetting out. Lay the clean, damp garment flat or hang it on a hanger. Spray the DWR treatment evenly over the entire exterior surface, holding the bottle about 6-12 inches away. Ensure complete coverage, paying extra attention to high-wear areas. Wipe off any excess or drips with a clean cloth.
Drying and Curing the DWR Treatment
Proper drying is essential for the DWR treatment to bond and cure effectively. After applying the DWR, follow the specific instructions on the DWR product. Many treatments require heat to fully activate.
If safe for your garment, tumble dry on a low to medium heat setting until completely dry. This heat helps to bond the DWR to the fabric fibers. If tumble drying is not an option, air dry the garment completely, then you can use a low-heat iron (with a towel barrier) or a hairdryer on a low setting to gently apply heat and aid the curing process.
Maintenance Tips for Longevity
Knowing how to restore waterproof clothing is only half the battle; proper maintenance will keep it performing its best for longer.
Wash Regularly: Clean your waterproof clothing as needed, using a technical fabric wash to prevent dirt and oils from building up and degrading the DWR.
Avoid Fabric Softeners and Bleach: These can damage the DWR and clog the waterproof membrane, reducing breathability and effectiveness.
Store Properly: Hang your waterproof gear in a cool, dry place away from direct sunlight when not in use.
Reapply DWR as Needed: When you notice water no longer beads, it is time to reapply the DWR treatment.
Common Mistakes to Avoid
To ensure you successfully restore waterproof clothing, be mindful of these common errors:
Using Regular Detergent: Standard detergents can leave residues that strip DWR and clog membranes.
Overwashing: While cleaning is important, excessive washing can wear down the fabric and DWR over time.
Not Rinsing Thoroughly: Any leftover soap from cleaning will prevent the new DWR from bonding properly.
Ignoring Care Labels: Always follow the specific care instructions provided by the garment manufacturer and DWR product.
Conclusion
Learning how to restore waterproof clothing is a valuable skill for any outdoor enthusiast.
