How Do You Clean Waterproof?

To effectively clean waterproof items, particularly waterproof jackets, you must use specialized products and methods to preserve their integrity and performance. Waterproof jackets should never be washed using ordinary detergent or fabric softener. The chemicals commonly found in these products can break down the composition of the fibers with each wash and strip the fabric of its essential waterproof coating. Instead, a cleaner specifically designed for technical outerwear is highly recommended.

Maintaining the cleanliness of your waterproof gear is crucial not only for hygiene but also for prolonging its life and ensuring it continues to repel water effectively.

Why Ordinary Detergents are Harmful to Waterproof Fabrics

Using standard laundry detergents or fabric softeners on waterproof materials, such as those found in high-performance jackets, can severely compromise their protective properties.

• Chemical Breakdown: The harsh chemicals in conventional detergents are designed to strip oils and dirt from natural fibers. When used on synthetic waterproof fabrics, these chemicals can degrade the specialized coatings and membranes that make the fabric waterproof and breathable.
• Coating Stripping: As mentioned, repeated washing with regular detergent actively strips away the Durable Water Repellent (DWR) finish, which is the initial barrier that causes water to bead up and roll off the fabric surface.
• Residue Build-up: Detergent residue can clog the microscopic pores of breathable membranes (like Gore-Tex or eVent), leading to a significant reduction in breathability and making the garment feel damp or clammy from the inside out. Fabric softener is particularly notorious for leaving residues that hinder breathability.

Recommended Cleaning Method for Waterproof Jackets

The most effective and safest way to clean waterproof jackets involves using dedicated technical cleaners. These cleaners are formulated to remove dirt and oils without damaging the DWR finish or the waterproof-breathable membrane.

Step-by-Step Cleaning Process:

1. Preparation:
   • Empty all pockets and close all zippers and fastenings (main zipper, pit zips, pocket zippers).
   • Loosen any drawcords.
   • Brush off any loose dirt or debris.
   • Check the care label inside your jacket for specific instructions.
2. Spot Cleaning (if necessary):
   • For heavily soiled areas, gently pre-treat with a small amount of the technical cleaner using a soft cloth or sponge.
3. Washing Machine Method:
   • Load: Place only the waterproof jacket (or a few similar items) in the washing machine. Avoid washing with heavily soiled items or anything that might damage the fabric (e.g., items with Velcro that can snag).
   • Dispenser: Clean out your washing machine's detergent dispenser to ensure no residual regular detergent is present.
   • Cleaner: Add the recommended amount of technical outerwear cleaner to the dispenser, following the product's instructions.
   • Cycle: Select a gentle cycle (e.g., delicate, synthetics) with cold or lukewarm water (check care label). A second rinse cycle can help ensure all cleaner residue is removed.
   • Spin: Use a low spin speed to avoid excessive creasing or stress on the fabric.
4. Hand Washing Method (for delicate items or extra care):
   • Fill a clean sink or tub with lukewarm water.
   • Add the recommended amount of technical cleaner.
   • Submerge the jacket and gently agitate the water.
   • Let it soak for 10-15 minutes, then gently rub any soiled areas.
   • Rinse thoroughly under cool, running water until all soap suds are gone.

Drying Your Waterproof Gear

Proper drying is essential for waterproof garments, as it can help reactivate the DWR finish.

• Air Drying: The safest method is to hang the jacket on a sturdy hanger in a well-ventilated area, away from direct sunlight or heat. Allow it to air dry completely.
• Tumble Drying (with caution):
  • If the care label allows, you can tumble dry on a low heat setting.
  • This gentle heat can help reactivate the DWR coating.
  • Place a few clean tennis balls in the dryer to help fluff the garment and prevent clumping.
  • Do not use dryer sheets.
  • Remove the jacket promptly once dry to prevent heat damage.

Re-waterproofing (DWR Reapplication)

Over time, even with proper cleaning, the DWR finish will wear off. When water no longer beads up on the fabric surface but wets out instead, it's time to reapply a DWR treatment.

• Wash-in Treatment: Applied in the washing machine, these treatments restore water repellency to the entire garment.
• Spray-on Treatment: Applied externally, these are ideal for targeting specific areas or for garments where only the outer fabric needs DWR restoration (e.g., lined jackets).

Always follow the instructions on the DWR product you choose. Often, a gentle heat application (like a low tumble dry or careful ironing) is required to activate the newly applied DWR.

Maintenance Tips for Longevity

Regular care goes a long way in extending the life and performance of your waterproof items.

• Frequent, Gentle Washing: Don't wait until your jacket is heavily soiled. Regular, gentle washes with the correct cleaner prevent dirt and body oils from degrading the fabric and DWR.
• Storage: Store your waterproof jacket unfolded in a cool, dry place. Avoid compressing it for long periods, as this can damage the membrane.
• Avoid Harsh Chemicals: Keep waterproof gear away from insect repellents, sunscreens, and strong chemicals that can damage the fabric.

Cleaning Summary for Waterproof Gear

By adhering to these guidelines, you can ensure your waterproof gear remains functional and durable for many adventures to come.
