2. Sun Hats
Nothing makes a statement like a big, floppy sun hat, but it’s bound to get dirty. For straw hats, remove any trim or sweat band that’s meant to detach — you can hand wash those separately. For the hat itself, a good rinse with your garden hose can usually remove any sweat, sand, or dirt, followed by an air-dry outside. If any sweat stains remain on light-colored straw, try mixing 1/2 teaspoon of hydrogen peroxide with an equal amount of warm water. For a darker straw hat, use 1/2 teaspoon of ammonia mixed with 1/4 cup warm water. Grab an old toothbrush and work the stain one small section at a time, then rinse again.
For fabric fedoras or similar style hats that may have sun lotion or other product on them, the top rack of your dishwasher can work just fine.
After washing, make sure your hats are totally dry before storing, so you don’t get that musty smell. If you’re not worried about fading colors, a couple of hours in the sun should be enough. However you wash your sun hats, pay special attention to maintaining the shape.
