Cleaning and re-waterproofing ski-wear

I have tried various products, but I would be very grateful to hear of other tips for cleaning/ waterproofing my ski jacket.

There comes a time when washing you coat becomes a necessity, but I've found even using nikwax products on my 700 down filled North Face Gore-tex jacket, it simply does not have anywhere near previous waterproof qualities in rainy scenarios.

Can any-one suggest an alternative method ?

the best products i have found are the grangers series, they use flouro chemicals to give the garment the same water repenellcy as new

the most important thing to do whatever product you use is to activate the product with heat

there are a few 2 in 1 solutions which are pretty good,if not using one of these you must wash the garment in a non detergent ligquid soap, powder clogs the pores of the gore tex

after the wash cycle and a further wash cycle with the proofer the garment must be either tumble dried on cool for 50mins or so or ironed with a cool iron, it is the heat which causes the water proofing chemicals to stick to the fibres and work properly

contary to popular belief gore tex loves to be washed properly, if it is not cared for the face fabric will wet out and this causes the garment not to breath correctly it is when this happens that normally it feels like the garment is leaking when it is actually persiration on the inside of the garment which cannot escape as the pores are blocked from the outside
