Before You Start
Before cleaning, check the label for fabric care instructions and test any cleaner on a small, inconspicuous area. Work on a clean, dry surface and use cold or lukewarm water to avoid color fading.

- Lightly mist the crown and brim, focusing on stained areas, then let the solution sit for 1–2 minutes.

- For tougher stains, apply a bit of the hat cleaner solution directly and work with the brush in small circular motions.
- Rinse a clean cloth with water and wipe away any soap residue from the hat’s surface.
- Reshape the crown gently with hands and place the hat on a clean towel to air-dry away from direct heat or sunlight.
- If the brim is especially dirty, repeat the cleaning cycle with minimal moisture and light brushing to restore the flat brim’s form.

- Reassemble any detachable parts and store in a cool, dry place to prevent mildew.
- For routine upkeep, spot-clean after wear and avoid soaking the entire hat.
