Ski clothing takes a beating. Storms, mud, the occasional rainstorm, plus ski edges and random tree branches all can leave your ski jacket and trousers looking like they've been run over by a truck. Underlayers can quickly develop a funky odour if not cleaned regularly. Cleaning your ski clothing has the added benefit of restoring its functionality while keeping you looking snazzy on the slopes. For outerlayers, a proper cleaning also helps keep you dry during big storms.
Separate outer and underlayers and wash them separately.
Place underlayers, such as long underwear and fleece jackets, in a cold cycle with a small amount of nondetergent cleaner and run the wash cycle. Tumble dry on a low setting.
Place the jacket and trousers in the washing machine on a cold cycle with some nondetergent cleaner and run the cycle.
Run the cold cycle again on the jacket and trousers, this time adding some of the wash-in water repellent to the cold cycle.
Tumble dry the ski clothing on a low cycle.
Wash down clothing separately from synthetics and the outer shells, using a product like Down wash to clean it. Air dry down clothing flat.
Washing machines without an agitator may work better for Gore-Tex products; some agitators can cause the Gore-Tex to delaminate.
