Nikwax Tech Wash

A non-detergent, biodegradable cleaner that removes dirt and detergent residue while leaving water repellency intact. As a result, water-repellent finishes last twice as long on garments washed in Tech Wash as those using detergent soap. Its highly effective cleaning agents and ability to rinse residue-free improve the perfomance of virtually anything made of fabric, fleece or synthetic insulation.
