Nikwax Tech Wash is absolutely essential for care of your Paramo Jacket or any waterproof and breathable fabric. Conventional laundry detergents leave behind a water attractive (hydrophilic) residue which masks the Durable Water Repellency (DWR), causing fabrics to absorb water and ‘wet out’ in damp or wet conditions. Therefore, they need to be avoided when cleaning waterproof clothing and equipment. Nikwax takes great care to minimise the effect of Nikwax products on the environment and on you, the consumer. Nikwax avoids materials in its cleaners like palm oil, which may be sourced from unsustainable plantations. Nikwax Tech Wash® is environmentally friendly; it is non-hazardous, WaterBased and biodegradable. It's incredibly easy to use in your washing machine. Technical cleaner for waterproof textiles Removes dirt and detergent residues from your garments Freshens and removes odours Revitalises breathability and restores water repellancy while cleaning your clothing Gives a superior clean, even at 30ºC
