Store your hat in a hatbox or on a flat shelf, in a cool dry place.
Felt/Wool, brush lightly with a clean soft brush or a lint roller for surface lint.
Straw, for stains spot clean gently with a slightly damp cloth, too much water will distort the shape.
Avoid using chemical cleaners on your felt/wool/straw hat as this may cause damage and discoloration.
