Nikwax Tech Wash 34 fl. oz. Technical Cleaner for Jackets - Restores

Our review of Nikwax Tech Wash finds it best suited to people who own technical outerwear and want a simple, safe way to clean and revive water repellency without damaging performance fabrics. The product is a soap-based, machine-wash cleaner formulated specifically for synthetic jackets, rain gear and ski layers, and it removes the water-attracting residues that household detergents leave behind. For anyone holding onto a GORE-TEX, Patagonia, Arc'teryx or similar shell, this cleaner restores breathability and helps existing DWR work more effectively, making it a practical maintenance step in gear care.

Key Features

• Safe for technical fabrics: Cleans synthetic outerwear without harming factory DWR or membrane performance.
• Removes residues: Lifts water-attracting detergent and sweat residues that reduce breathability and cause wetting out.
• Machine wash friendly: Designed as an easy wash-in cleaner so routine gear maintenance is straightforward.
• PFAS-free and water based: Uses non-persistent ingredients with no optical brighteners or added scent for neutral fabric care.
• Prepares for waterproofing: Enhances the effectiveness of subsequent Nikwax waterproofing treatments when used beforehand.
• Measured dosing: One full cap equals approximately 50ml for consistent dosing per load.

Who It's For

People who regularly use technical shell jackets, ski clothing or synthetic sleeping bags and want to maintain waterproofing and breathability will appreciate Tech Wash. It is particularly useful for owners of GORE-TEX and branded technical shells from Patagonia, The North Face, Columbia, Outdoor Research and Arc'teryx who need a cleaner that will not leave harmful residues.

Those looking for an all-purpose household laundry detergent or a cleaner for natural fibers should look elsewhere, since Tech Wash is formulated for technical synthetics and to work as a preparatory step before applying waterproofing treatments.
