Hey all, here's a question. I managed to score an Imperial Stetson for practically nothing. The felt is wonderful, but it's got what I suspect are mildew spots on it - both on the hat and on the ribbon. (I'm guessing it's mildew from the smell.) I've been fortunate in that I've rarely bought a hat with mildew problems on the outside. Am I going to hurt the hat at all by trying to clean it, and what would anybody recommend for cleaning? I don't think I've ever used anything on my hats other than a damp, soft cloth. Will I make things worth with the damp cloth? The hat is a toffee-colored brown, and it has a Cavanagh-edge.
