In addition to regular after-wear maintenance, you may deep-clean your straw hat using things you already have around the house, such as regular old window cleaner. If you prefer something tougher, invest in a bottle of Straw Hat Cleaner that will safely remove residue, dirt and grime from colorfast straw hats.
Keep clean and fresh by brushing with a small whisk broom or sponge lightly with a damp cloth. Use window cleaner for heavier stains.
Store hat on its top or hang from a peg or hat hook to help it retain its shape.
Keep most straw hats from getting soaked with rain. If your hat gets wet, wipe off the excess water with a dry cloth. Then, with the brim turned up, place on a level, clean surface to dry.
Steam your hat to reshape, if necessary.
Do not use artificial heat.
