9 Best Ways to Wash a Baseball Cap and Keep It Looking New

Your favorite baseball cap has seen better days, but tossing it in the washing machine isn’t always the best option. Whether it’s a prized souvenir from a memorable game or just your go-to accessory for sunny days, knowing how to clean it properly can extend its life and keep it looking fresh.

Assess Your Baseball Cap Material

Before you start cleaning your cap, it’s crucial to know its material. Different fabrics require different cleaning methods.

Check the Label

Examine the label inside your cap. Often, it provides cleaning instructions and material details. Follow these guidelines to avoid damaging your cap.

Identify Material Type

Determine if your cap is cotton, wool, polyester, or a blend. Cotton caps are usually machine washable, while wool caps need gentle hand washing. Polyester caps often tolerate more rigorous cleaning, and blends may require mixed methods. Adjust your cleaning approach based on the material for the best results.

Prepare Your Baseball Cap for Washing

Before diving into the washing process, proper preparation ensures effective cleaning. Follow these steps to get your cap ready.

Remove Surface Dirt and Stains

Gently brush off loose dirt using a soft-bristled brush or cloth. Pay attention to areas around the brim and seams. This prevents surface grime from embedding deeper during the washing process. Check for visible stains and note their locations.

Pre-treat Stains

Apply a small amount of mild detergent or stain remover to the stained areas. Use an old toothbrush or soft cloth to gently work the solution into the fabric. Let it sit for about 15-30 minutes to break down the stains. Make sure to follow any specific product instructions to avoid damaging the material.

Hand Washing: The Safest Method

Hand washing your baseball cap is the safest method to preserve its shape and color.

Gather Your Supplies

Collect a mild detergent, a soft brush (like an old toothbrush), a clean cloth, and a basin or sink filled with cool water. Ensuring you have everything ready makes the washing process seamless and efficient.

Gentle Washing Techniques

Submerge your cap in cool water mixed with a small amount of mild detergent. Gently agitate the water to create suds without being too rough. Use the soft brush to delicately scrub any remaining stains, focusing on problematic spots. Be careful around the brim and seams to avoid deformation. Once the stains are addressed, rinse your cap thoroughly with cool water to remove all detergent. Avoid wringing your cap; instead, press gently to release excess water. Then, air dry it on a clean towel, reshaping it as needed.

Machine Washing for Durable Caps

For sturdy baseball caps, machine washing can be effective if done correctly. Follow these steps to keep your cap in great shape.

Picking the Right Washer Settings

Choose the gentle cycle on your washing machine to minimize agitation. Use cold water to prevent colors from fading. Add a mild detergent to clean your cap without harsh chemicals. Avoid using bleach, as it can ruin your cap’s fabric and color.

Using a Protective Case

Place your cap in a protective laundry cap or a mesh bag. These bags prevent the cap from losing its shape and protect decorative elements like embroidery. Make sure the case is securely closed before placing it in the washer. By using a protective case, you ensure your cap retains its structure and design after washing.

Spot Cleaning for Quick Touch-Ups

Sometimes, your baseball cap needs a quick refresh without a full wash. Follow these steps for effective spot cleaning.

Choosing the Right Cleaner

Pick a gentle cleaner for your cap. Mild dish soap or baby shampoo works best. Avoid harsh chemicals— they can damage the fabric and discolor your cap. Test the cleaner on a small, hidden area to ensure it doesn’t stain.

Spot Cleaning Procedure

Moisten a clean cloth with warm water and apply a small amount of cleaner. Gently dab the stained area, working from the outside in to avoid spreading the stain. Avoid soaking the cap; you just want to dampen the area. Rinse the cloth, dab off any residual cleaner, and let the cap air dry.

Drying Your Baseball Cap Properly

How you dry your baseball cap is crucial to maintaining its shape and integrity. Using the right techniques will help preserve your cap’s fit and look.

Avoid the Dryer: Air Drying Techniques

Avoid using the dryer at all costs. High heat can warp the cap and ruin its structure. Instead, air drying is the best method. Use a clean towel to blot excess water gently. Avoid wringing or twisting the fabric. Let your cap air naturally on a flat surface. You can place it on an upturned bowl or a rounded object to maintain its shape while drying.

Reshaping Your Cap While Damp

Reshape your cap immediately after washing, while it’s still damp. Mold the brim back to its original shape. If your cap has a structured crown, you can stuff it with a dry towel to maintain its form. This ensures your cap looks as good as new once it’s fully dried.

Maintaining Cap Shape and Color

Keeping your baseball cap looking new involves a bit of attention to detail. Here’s how to maintain its shape and color effectively.

Storing Caps Correctly

Store your caps properly to keep their shape intact. Use a hat rack or hooks to hang them when not in use. For long-term storage, consider using a cap organizer or placing tissue paper inside the cap to help retain its form. Avoid stacking caps, as it can cause them to lose their shape.

UV Protection and Color Fading

Protect your cap from sun damage that can fade its color. When not being worn, store your cap in a shaded area. Consider using a UV-protection spray designed for fabrics to shield it from harmful rays. Make sure to follow the product instructions carefully for best results. Similarly, avoid leaving your cap in direct sunlight for extended periods, especially in a car, to prevent color deterioration.

Special Tips for Vintage or Autographed Caps

Treat vintage or autographed caps with special care to preserve their value and condition.

Handling With Care

Preserve your cap’s condition by handling it gently. When touching the cap, always use clean hands to prevent oils and dirt from transferring. Avoid pinching or folding the brim, as this can cause permanent creases. Store the cap in a cool, dry place away from direct sunlight to prevent fading and wear.

Alternative Cleaning Options

Protect your cap’s integrity by skipping traditional washing methods. Instead, use a soft-bristled brush to gently remove dust and debris. For stains, dampen a microfiber cloth with water and mild soap, then blot the spot carefully. Avoid soaking the cap, as water can damage delicate materials and signatures. You can also use compressed air to blow off loose dirt without touching the fabric.


Taking proper care of your baseball cap ensures it stays in top condition for years to come. By following the right washing techniques and drying methods, you can maintain the cap’s shape and color. Remember to handle vintage or autographed caps with extra care to preserve their value. Using gentle cleaning products and avoiding harsh methods will help protect your cap’s integrity. With these tips, your favorite cap will always look its best.
