Dan D is right. Gore recommends powdered detergent or Nik-wax tech wash (which is a liquid, but NOT a detergent), and machine washing. NEVER dry clean Gore-tex. The second thing you need to do is to renew the DWR (durable water repellancy) on the outer surface of the jacket fabric that keeps the rain or snow beading off the fabric surface. Goretex is a membrane on the inside of the fabric, but the outer surface of the shell is coated (or in some cases impregnated) with some sort of stuff that is hydrophobic. This is what prevents "wet-out" , the condition that occurs when the shell fabric becomes totally drenched with water. When this happens, the goretex membrane can no longer breathe, and you get wet and clammy. There are 2 ways to renew the DWR. 1. toss the jacket in the dryer, or iron it- heat will do it. 2. Use Nikwax wash in (best for older jackets, and works great once a year in any case). See the Goretex and Nik-wax web sites for more information. As far as I know, these guidelines are the same for Goretex competitors like Marmot Membrain, Conduit, Entrant, etc.
