Nikwax Tech Wash is a cleaner specifically designed for waterproof and water-resistant garments. When dirt gets into your garment it can compromise the DWR's ability to repel moisture. This clogs up the pores of the fabric and compromises breathability. It also causes the fabric to become saturated which can then cause conductive heat loss. Regular detergents can damage DWR or leave behind a residue. Nikwax Tech Wash is designed to clean your garment while revitalizing the DWR for better performance. Nikwax is easy to use and it's water-based and biodegradable.
