cleaning a hat?

got a nice hat (a real ht not ball cap, one of those old folks type hats), but its satrting to look a lil funky. it doesnt have any cleaning instructions, and i dont have a clue as to how to get it cleaned. its not on the tag inside the hat, all that says is “35% wool 50% acrylic 15% nylon” any help?

You probably need to have it drycleaned, unless you have a hat form to block it after washing.
