I guess this is what Gore says:
quote:
Regular wear and tear, plus exposure to dirt, detergents, insect repellant, and other impurities, causes DWR failure. DWR is not permanent on any fabric. Its effective life depends upon how you care for your garment and how rigorously it is used. The most effective way to maintain your Gore garment's water and stain repellency is to wash it, rinse it, and put it in your dryer. The washing removes contaminants and the heat from the dryer helps redistribute the DWR treatment on the fabric surface.I wash my GT jacket at least once a year, warm water, tumble dry on med. water beads up like a maniac still after 5 years...That's not to shabby. I've never used revivex, but have heard good thing, probably try it soon.
cheers.
