Sometimes a good couple of cycles in the washing machine with lots of detergent can restore waterproofness. When I was commuting to London in all weathers my gear got very grimy after a few weeks and they started to let in water even in mild downpours. Someone told me that goretex stops working if dirt gets in because the particles of dirt act like a wick letting water through the membrane, which makes sense I suppose. Maybe that's what the Nikwax wash is all about.
