When cleaning your hat, you must be as gentle as possible. This hat brush is made of 100% ultra-horsehair, so it will easily make your hat look fresh and clean. It will safely remove the dust and lint, and the fine hair on the brush is safe enough that it will not tear or scratch the felt. Your hat will look brand new! I suggest you brush it in a counterclockwise motion on the top side of the hat and clockwise for under the brim. Hats are finished in a way (usually with a sanding device) that often puts a certain grain to the nap. That's why you want to brush counterclockwise. You'll be surprised how vibrant the fur-felt will look after a good, soft and proper brushing!
