How to Clean and Care for a Straw Hat

1. Remove Ribbons and Trim When Possible

   If your hat has any ribbons or trim, remove them before you begin the cleaning process. Clean them separately by dusting or hand-washing. They can often be refreshed with a bit of steam or ironing.

2. Wipe Down the Hat

   Whether you have a natural straw hat or one made of a synthetic material, begin by using a clean, damp white cloth to remove any loose dirt or dust. Don't use a colored cloth, as the dye may transfer to the straw. If you need to get into the crevices, use a soft-bristled brush, brushing from the top of the crown to the brim.

3. Use a Vacuum Attachment

   If your hat is really dusty or sandy, place a piece of netting or pantyhose over the end of your vacuum brush, and use it to pull debris from the hat.

4. Wipe with a Cleaning Solution

   Make a solution of a few drops of mild dishwashing liquid and water. Wet a soft cloth, and test a small area of the hat to make sure the water doesn't cause any adverse effects. Once you know it's safe, wipe the hat in a circular pattern to avoid damaging the straw. Finish by wiping with a clean cloth dipped in water, and then use a clean dry cloth to soak up the excess water.

Ironing

If you have a hat with a veil that can't be removed, use steam from an iron or a clothes steamer or hold the fabric over a pot of boiling water to carefully reshape a crushed veil. Don't over-steam, or the entire hat can lose its shape. 

Storing a Straw Hat

Always store straw hats in a cool, dry place. If the brim is curved, store the hat upside down in a hatbox to prevent misshaping the brim and to keep off dust. Or, use a mannequin head form, and cover the hat and head loosely with a white cotton pillowcase to repel dust. Never store a straw hat in a plastic bag, which can cause discoloration and promote mildew.

Repairs

If you have a small tear in your hat, use a matching color of mesh netting to repair it in the following three steps. Your patching effort may be noticeable, but it will stabilize the straw.

1. Cut out three pieces of netting that are a bit larger than the size of the hole.
2. Place the netting, each piece stacked on top of each other, on the back of the hole inside the hat.
3. Use a needle and matching thread to hand-sew the netting to the hat by pushing the needle through the netting and the gaps in the straw's weave.

Treating Stains on Straw Hats

Perspiration is the usual culprit when it comes to stains on straw hats. To remove perspiration stains from a hat, wipe the area with a clean, damp white cloth as soon as possible after wearing to prevent body salts and oils from staining the straw.

For stains around the sweatband, use 1/2 teaspoon hydrogen peroxide and 1/2 teaspoon warm water on light-colored straw. For dark straw, use 1/2 teaspoon ammonia and 1/4 cup warm water. Use a soft-bristled brush, like an old toothbrush, dipped in the cleaning solution, and work on a small area, just one to two inches, at a time. Clean, and then blot with a white towel dampened with water. Allow the area to dry completely before wearing again.

For oily stains, sprinkle the stain with cornstarch or talcum powder to absorb the oil. Allow it to stand for a few hours, and then brush or vacuum away.
