Tech Wash is a non-detergent 'pure soap' cleaner that is added to your washing machine in place of your normal powder. It safely penetrates and lifts dirt and oils without damaging technical fabrics like Gore-Tex or eVent, and prepares them for re-proofing if required.Once clean, your clothing can be reproofed by washing again with TX Direct Wash In. This revitalises the durable water repellent finish on the outside of the fabric so rain will bead up and run off rather than soaking in.
