Yes Nikwax Techwash-do mine in the washing machine @ 30 C This cleans out the grease & dirt. Then reproof with Nikwax spray while jacket/trousers still damp. Both have stayed completely waterproof since 2005 when bought. Only need to do this once a year. Also have one of those Aldi Hi-viz jackets which seems pretty good although pockets not as good as more expensive brands-but for the money...great value!
