tech wash is good
I used Tech Wash to clean my Gore-Tex jacket after a week-long trip. This product worked great, not only did it get the stink and dirt out, it kept the water repellency. Later, I made the mistake of washing the jacket with detergent. With the next rain storm, I found out the hard way, Tech Wash is the only way to go. The water repellency of the jacket was shot.
