Omg this drives me nuts. DH's work shirts, it always happens to them. He admits he wears too much deodorant but that's not an easy habit to break or one he's willing to break. How can I get them clean? Not only how do I remove the crustiness but is there something I should be doing before this happens to prevent it from happening? I am literally useless at household stuff. I have a whole host of questions to start threads about but thought I'd tackle this one first.
