Forgive me if this has already been posted. With the summer month coming up, how do you keep a straw cowboy hat from getting sweat stains? I have an old George Strait straw Resistol that I got back in ‘98 that has all kinds of sweat stains. I just picked up a Cody Johnson straw Resistol and with the heat coming, do not want sweat stains destroying the hat. Is there a good way of preventing them? Thanks.
