Color test the fabric of your hat

Test to make sure your hat will stand up to the cleaning process by rubbing a small amount of cleaning solution like Swash® Laundry Detergent1 or a powdered stain remover mixed with water on a hidden part of the hat, like the underside of the bill.

How do you clean vintage baseball hats?

Since older hats often have cardboard bills instead of today’s more durable plastic, avoid soaking the hat and spot clean only to preserve the material. Generally, hats made prior to 1983 will have a cardboard bill—if the hat makes a hollow sound when you flick or tap the bill, you can probably assume that it’s cardboard.

Can you wash a baseball cap in the dishwasher?

It’s not recommended to wash a baseball cap in the dishwasher. While you may have heard that it’s okay to clean a hat in the dishwasher, the high heat and harsh, bleach-based dish detergents can damage fibers and remove color from the hat. Wash your baseball caps by hand to help avoid potential damage.

Can you wash a baseball cap in the washing machine?

It’s possible to wash a hat in the washing machine using the Delicates/Gentle cycle, but you still run the risk of the hat losing its structured shape due to friction and pressure caused by the washer’s agitation. To help keep hats looking great for as long as possible, avoid washing them in the washing machine and hand clean them as needed.

How to wash a baseball hat by hand

As long as it’s not a vintage hat, needing special care, spot clean the hat with mild, diluted detergent before submerging it completely in water. Let it soak for up to 15 minutes. Then, rinse the hat thoroughly in warm or cold water before gently patting it dry with a towel, reshaping it and leaving it to air dry.

5. Reshape the hat and drip dry

Reshape the hat by placing the cap (the part that sits directly on your head) on top of an upside down coffee can, small bowl or other container that mimics the shape of your head. Leave the hat out to dry.

 

Cleaning tip: Take extra care when cleaning wool baseball caps since the fabric is more delicate and prone to losing its shape. Use a mild detergent specifically designed for wool, dilute it in water and scrub gently. Reshape the hat either by wearing it until dry or placing it on something that mimics the shape of your head.
