How to Clean a Hat in the Dishwasher

Quck answer

Washing a hat in a dishwasher can be a convenient and effective way to clean it. Here are the steps to follow:

1. Check the hat’s label to see if it is dishwasher safe. Not all hats can withstand the heat and agitation of a dishwasher.

2. Remove any detachable components, such as stickers or patches, from the hat.

3. Place the hat in the top rack of the dishwasher, ensuring it is secure and won’t move around during the wash cycle.

4. Use a mild detergent and set the dishwasher to a gentle cycle with cool water.

5. Avoid using any heat drying settings as they can damage the hat’s shape. Instead, let the hat air dry naturally.

6. Once dry, reshape the hat if needed and it’s ready to wear again.

By following these steps, you can easily and safely wash your hat in a dishwasher, saving time and effort.


Using a washing machine to clean a hat may remove dirt from the fabric but can also distort its shape. This is especially true for baseball caps, as a damaged brim can obstruct the wearer’s vision and fail to provide protection from the sun. Additionally, a misshapen hat loses its aesthetic appeal.

Hat Cleaning Methods

Before risking damage to your favorite hat by using a washing machine for cleaning, it’s important to learn some tips for hat care and maintenance. One option is to use a dishwasher, which is actually a safe way to clean a baseball cap. Alternatively, you can use a hat frame to wash the hat in a washing machine. For older or delicate hats, spot cleaning is the safest method.

Is Spot Cleaning Recommended?

Check the inside of the hat for a care tag that provides information about the hat’s material. Wool caps require special attention when it comes to water temperature and should be spot cleaned or hand-washed. Hats with cardboard brims should also be spot cleaned, as soaking them in water can permanently damage the cardboard.

Cardboard brims are typically found in older, classic hats, while modern hats usually have plastic brims. If you’re unsure about the material of your brim, you can look up the specifications online or opt for spot cleaning to be safe.

To spot clean a hat, mix approximately 1 tablespoon of gentle hand-washing detergent, such as Woolite, with 1 gallon of warm water. You can either soak the hat in the soapy water and gently rub the fabric to remove dirt, or use a clean cloth soaked in the water to apply the soap suds. Allow the detergent to penetrate the fabric, then remove it with the cloth or rinse the hat with lukewarm water.

Cleaning a Hat in the Dishwasher

To clean a baseball cap in the dishwasher, place the hat on the top rack with or without a protective hat frame. It’s advisable to run the dishwasher without any dirty dishes to prevent food particles from settling on the fabric. Use your regular dishwasher detergent, but avoid using the hottest setting or a heated dry, as the plastic brim may distort due to the heat.

Cleaning a Hat in the Washing Machine

When washing a baseball cap in a washing machine, it’s crucial to use a hat frame. This frame prevents the hat from getting crumpled by the washing machine’s agitator and pressure during the spin cycle. Use your regular laundry detergent and select a gentle setting with warm water.

Drying a Hat

Never put a wet baseball cap in the dryer, as it will shrink regardless of whether it’s made of cotton or polyester. Instead, place it on a towel to air dry.

If you didn’t use a hat frame, the hat may be slightly misshapen after washing. To reshape the hat and prevent major wrinkles, place it over a balled-up towel that fills the entire cavity. You can also use a wrinkle release spray if any wrinkles do appear.
