Bought a Ventile Smock / Windshirt late last year and have used it regularly for bumbling around in the hills since then ... and a good buy it was too ... however it is now in need of a wash . Have checked on the Interweb and what I intend to do is to handwash in a liquid soap or Lux /rinse / reproof with appropriate Nikwax . I am going to chose a good drying day and finish it off by hanging it out in the back garden . Any hints tips would be appreciated ... I do not want to sh*g it with the first wash .
