Hi Richard, here is some instruction for you

Cleaning Fur Felt Hats & Wool Hats

1. To clean a fur felt hat or wool hat, brush the top and bottom counter-clockwise with a soft bristle brush.
2. Set your hat on its top or hang from a peg or hat hook to help it retain its shape.
3. If your hat gets wet, shake off all excess water, let dry, then lightly brush clean.

How about using a sticky clothes roller to remove any dust build up for the felt one. And a suede brush for the suede one. Decker is right in saying go in one direction.

Have you tried the home dry clean method you buy at the store
