DH is trying to clear health issues with recurring thrush & fungal foot infection. He's made diet changes recommended by a nutritionist & on prescription cream. Nutritionist raised point which we hadn't thought of that he could be reinfecting himself through clothes & towels. I've just put our bedding through a 60 wash but not sure the elastic in his boxers and socks will stand up to such a hot wash. Does anyone know of anything I can use in the machine which will kill fungus? Do Dettol or Napisan work?
