How to Wash a Baseball Cap
A structured cap holds its shape with a stiffener in the front panels that a washing machine can crush. Hand washing is almost always the safe choice, and it keeps the embroidery crisp.
- Fill a sink or bucket with cool water and a small amount of mild detergent.
- Spot-clean the sweatband and any marks with a soft brush.
- Submerge the cap and gently agitate for a few minutes. Do not wring or twist.
- Rinse in clean cool water until no suds remain.
- Press out water in a towel, reshape the crown, and let it air dry over a round container.
Common Mistakes to Avoid
- Machine washing a structured cap, which crushes the brim and front panels.
- Hot water, which shrinks the band and fades the thread.
- A clothes dryer, which warps the brim. Always air dry.
