Nikwax Tech Wash
Detergents can diminish the durable water repellency (DWR) of a technical fabric. Opt for Tech Wash instead.
Use Nikwax Tech Wash to clean and care for your waterproof/breathable garments. Dirt will attract water and reduce the beading-up of droplets on the fabric's surface. Plus, after a couple days out in the backcountry, your shell reeks. Wash the garment in Nikwax Tech Wash non-detergent soap. Detergents can leave water-attractive residues that will not rinse out. They also contain agents that can wash away water-repellent treatments. Never use liquid detergents or fabric softeners. 10 fl oz. (300 ml)
