Step-by-Step Method
Zip up all zippers. Fasten all Velcro tabs (loose Velcro damages fabric in the wash). Empty pockets.
Use a technical fabric wash (NOT regular detergent) on gentle cycle with warm water. Regular detergent leaves residue that clogs the membrane pores and destroys breathability.
Tumble dry on low-medium heat for 20-30 minutes. Heat reactivates the DWR (Durable Water Repellent) finish on the outer fabric. This is essential.
If water soaks into the outer fabric instead of beading after the heat treatment, apply a DWR reproofing spray or wash-in reproofer per product directions.
- Never use regular detergent (clogs the waterproof membrane)
- Never use fabric softener (coats the membrane and kills breathability)
- Never dry clean (solvents damage the membrane)
- Do not wring or twist
- Gore-Tex works by having billions of tiny pores that are too small for liquid water but large enough for water vapor (sweat). Detergent residue blocks these pores.
- Wash your Gore-Tex jacket. Dirt and body oils clog the pores and reduce breathability. A clean Gore-Tex jacket performs dramatically better than a dirty one.
- The outer DWR wears off with use and washing, but can be reapplied indefinitely.
Frequently Asked Questions
Two causes: the DWR (Durable Water Repellent) on the outer fabric has worn off, or body oil and detergent residue is clogging the membrane. Wash with technical wash, tumble dry to reactivate DWR, and reproof if needed. The Gore-Tex membrane itself does not wear out.
Sources & Methodology
Gore-Tex care per W.L. Gore manufacturer guidelines. DWR reactivation through heat is the standard restoration method for fluoropolymer-based water repellent finishes.
