More information on Foul Weather Gear Waterproofing & Cleaning:
Restoring a DWR coating is easy -- we recommend starting with the ReviveX Cleaner, which is designed to clean technical fabrics and properly prepare them for revitalization. This cleaner works easily in your home washing machine; just follow the instructions. After using the cleaner, revitalize the DWR coating using either the ReviveX Water Repellent Spray or Gill Wash-In Water Repellent. The first is an easy to use waterproofing spray that quickly and easily sprays onto your garment, bonding with the fabric or existing DWR coating to revive and protect your foul weather gear. The second is even easier to use -- just add the wash-in repellent to a second washing machine cycle for no fuss application.
