Often asked: How To Wash Dwr Clothing?

Regular Washing

  1. Wash the garment with an additive-free detergent like Nikwax Tech Wash (not liquid detergents or anything that contains fabric softeners as these can impact the effectiveness of the DWR finish).
  2. Before washing, read the care label inside the jacket and follow any specific instructions provided.

Does washing remove DWR?

First step: cleaning. Washing away dirt and oils does much to restore DWR water-shedding abilities. You can usually find care instructions on the label or on the manufacturer’s website. Technical fabric cleaners work best for this because they contain no additives that can interfere with garment performance.

Is DWR toxic?

The DWR we used as a standard for years was a long-chain (C8) fluorocarbon-based treatment that is highly effective and extraordinarily durable. Unfortunately, its by-products are toxic and persist in the environment, a combination that makes it unacceptable despite its excellent performance.

Does DWR mean waterproof?

Durable water repellent, or DWR, is a coating added to fabrics at the factory to make them water-resistant (hydrophobic). Durable water repellents are commonly used in conjunction with waterproof breathable fabrics such as Gore-Tex to prevent the outer layer of fabric from becoming saturated with water.

How long do DWR coatings last?

Like all good things, the waterproof nature of Gore-tex fabric will weaken over time and diminish in performance. At this time it will require some maintenance to restore its waterproof nature. Reproofing your jacket is quick and easy and recommended to be done every 3-6 months, or after a particularly heavy use*.

Is DWR breathable?

On outerwear and accessories with waterproof/breathable membranes like Gore-Tex, DWR prevents them from becoming saturated—a condition known as “wet out”—which can leave users feeling damp and clammy, as well as inhibit breathability.

How do I reactivate my DWR?

Follow the wash instructions for your product, then line dry your garment, or tumble dry it on a warm, gentle cycle. Once it’s dry, tumble dry your garment for a further 20 minutes —this will reactivate the durable water-repellent (DWR) treatment.

What is DWR treatment?
