How to Wash a Baseball Cap in a Dishwasher

Baseball caps are not only a stylish accessory but also a functional item that shields us from the sun and adds a touch of personality to our outfits. Over time, these caps can accumulate dirt, sweat, and odors, making them in need of a thorough cleaning. While many people resort to hand washing their baseball caps, did you know that you can wash them in a dishwasher? In this article, we will guide you through the steps of washing a baseball cap in a dishwasher, ensuring it comes out clean and fresh without losing its shape or color.

Importance of Washing Baseball Caps

Regularly washing your baseball cap not only helps maintain its appearance but also contributes to its longevity. Sweat, dirt, and oils can accumulate on the cap’s surface, leading to discoloration, odors, and even potential damage to the fabric. By washing your baseball cap, you can keep it looking and smelling great while extending its lifespan.

Preparing the Baseball Cap for Dishwasher Washing

Before placing your baseball cap in the dishwasher, it’s important to prepare it properly. Start by inspecting the cap for any loose threads or damaged areas. If you notice any, it’s best to repair them before washing to prevent further damage. Additionally, check the care instructions on the cap’s label to ensure it is dishwasher safe.

Choosing the Right Dishwasher Cycle

To effectively wash your baseball cap, it’s crucial to select the appropriate dishwasher cycle. Opt for a gentle or delicate cycle that uses lower temperatures and less agitation. Avoid using a cycle with a drying feature, as the high heat can misshape the cap or cause the colors to fade.

Using Dishwashing Detergent

Next, choose a mild dishwashing detergent for cleaning your baseball cap. Avoid using bleach or harsh chemicals, as they can damage the fabric. Instead, opt for a gentle detergent that is suitable for delicate items.

Placing the Baseball Cap in the Dishwasher

To protect the shape of your baseball cap during the dishwasher cycle, it’s essential to use a cap frame or a specialized cap washer. These accessories keep the cap in place and prevent it from losing its shape or getting crushed by other items in the dishwasher. Place the cap frame or cap washer in the top rack of the dishwasher, ensuring it is secure.

Adding Extra Protection

If you’re concerned about the colors of your baseball cap fading or bleeding, consider placing it inside a pillowcase or a mesh laundry bag before putting it in the dishwasher. This extra layer of protection can minimize any potential damage caused by direct contact with the dishwasher’s water jets.

Running the Dishwasher Cycle

Once your baseball cap is securely placed in the dishwasher, it’s time to start the cycle. Close the dishwasher and select the appropriate settings. Remember to choose a gentle cycle with lower temperatures and minimal agitation to prevent any potential damage to the cap. Start the dishwasher and allow it to complete the washing cycle.

Drying the Baseball Cap

After the dishwasher cycle is complete, avoid removing the baseball cap immediately. Let it air dry inside the dishwasher to minimize the risk of shrinking or losing its shape. Opening the dishwasher door slightly can help speed up the drying process.

Removing Wrinkles and Reshaping

Once your baseball cap is dry, you may notice some wrinkles or slight deformations. To address this, use a fabric steamer or a clothing iron set to low heat. Gently steam or iron the cap, reshaping it back to its original form. Be cautious not to apply too much heat or pressure, as it can damage the cap.

Hand Washing Alternative

If you prefer not to use the dishwasher, you can still hand wash your baseball cap effectively. Fill a basin or sink with lukewarm water and add a small amount of mild detergent. Gently agitate the water to create suds, then submerge the cap and scrub it lightly using a soft brush. Rinse thoroughly and follow the drying and reshaping steps mentioned earlier.

Cleaning the Sweatband

The sweatband on a baseball cap often absorbs sweat and oils, resulting in unpleasant odors. To clean the sweatband, create a mixture of warm water and mild detergent. Dampen a clean cloth or sponge with the soapy water and gently wipe the sweatband. Rinse the cloth or sponge frequently and continue until the sweatband is clean. Allow it to air dry completely before wearing the cap.

Stain Removal Techniques

If your baseball cap has stubborn stains, there are a few techniques you can try. For grease or oil stains, apply a small amount of dishwashing liquid directly to the stain, gently rub it with a soft brush, and let it sit for a few minutes. Then, rinse with warm water and repeat if necessary. For ink stains, use a cotton swab dipped in rubbing alcohol to dab the stain until it lifts. Always test any stain removal method on a small, inconspicuous area of the cap first to ensure it doesn’t cause any discoloration or damage.

Maintaining the Shape of the Baseball Cap

To keep your baseball cap in good shape between washes, avoid placing heavy objects on top of it and store it in a cool, dry place. Consider using a cap rack or a cap storage system that allows the cap to maintain its shape while being stored. Avoid folding or crushing the cap, as this can lead to permanent deformations.

Can I wash a baseball cap with other dishes in the dishwasher?

No, it’s recommended to wash your baseball cap separately in the dishwasher to avoid any potential damage caused by other dishes or utensils.

How often should I wash my baseball cap?

The frequency of washing depends on how frequently you wear the cap and the level of dirt and sweat accumulation. As a general guideline, washing it every few weeks or when it appears visibly dirty is a good practice.

Can I wash a baseball cap made of wool in the dishwasher?

No, it’s not advisable to wash a woolen baseball cap in the dishwasher as it can shrink or lose its shape. It’s best to follow the care instructions provided by the manufacturer for woolen caps.

Are all baseball caps dishwasher safe?

Not all baseball caps are dishwasher safe. It’s important to check the care instructions on the cap’s label before attempting to wash it in the dishwasher.

Can I use fabric softener when washing a baseball cap in the dishwasher?

No, it’s best to avoid using fabric softener when washing a baseball cap in the dishwasher as it can leave a residue and affect the cap’s appearance and texture.


Washing a baseball cap in the dishwasher is a convenient and effective method to keep it clean and fresh. By following the steps outlined in this article, you can ensure your cap remains in great condition while retaining its shape and color. Whether you choose the dishwasher or hand washing method, proper care and maintenance will prolong the lifespan of your beloved baseball cap.
