How to Wash Hats: Restore Your Favorite Caps to Pristine Condition

Whether it’s your favorite baseball cap, a vintage-style hat, or a wool bucket hat, your headwear goes through a lot. Over time, it collects sweat stains, dirt, and oils from your skin.

But here’s the good news: you don’t need to toss your favorite hat or let it gather dust in the closet. With the right washing process, you can restore even the filthiest baseball caps and oldest vintage hats to like-new condition.

The most important thing is to use the best approach based on the hat’s material and structure. In this guide, we’ll explain the safest ways to wash baseball hats—both by hand and in a machine.

Understanding Your Hat: Materials and Construction

Before you begin cleaning, the first thing to do is understand what your hat is made of. This is essential because different materials require different cleaning methods. For example, wool baseball caps and vintage-style caps often include delicate materials that can shrink or warp when exposed to high heat or water.

A hat with a cardboard brim, sometimes called a cardboard bill, should never be submerged in water. While, newer hats usually have plastic inserts that are more durable and machine washable.

To figure this out, press on the brim. If it makes a hollow sound and gives slightly, there’s a good chance it contains a cardboard insert. Also, check the care label or care tag inside the hat, as this often indicates the safest cleaning method.

Key Takeaway

• Always check your hat’s material and construction before cleaning—different fabrics and brims require different care methods.
• Hand washing is the safest and most effective method for most hats, especially vintage or delicate ones.
• For sturdier hats, machine washing or dishwasher cleaning can work, but only with the right precautions.
• Proper air drying and gentle maintenance are essential to preserving your hat’s shape, color, and longevity.

How to Care for Your Vintage Hat: A Step-by-Step Guide

Here are step-by-step tips for cleaning, washing, and drying your vintage hat without damaging its delicate material.

1. Hand Wash vs. Machine Wash

When it comes to preserving a hat’s shape and protecting its delicate materials, hand-washing is the best method. Here’s how to do it properly:

• First, fill a clean sink or bucket with cool or cold water.
• Next, add a tablespoon of laundry detergent or a mild detergent suitable for delicate fabrics.
• Then, if your hat has sweat stains or visible grime, apply a stain remover to the affected area and let it sit for a few minutes.
• After that, gently submerge the hat and use a soft-bristled brush or soft brush to scrub in a circular motion, especially on stained areas.
• Once done, rinse thoroughly with cool water to remove all soap residue.
• Finally, press out excess water using a clean towel or paper towel.

Following these steps will keep your hat in great condition, preserving its shape, color, and durability for years.

Machine Washing: Best for Newer, Durable Hats

Some hats—particularly those with plastic brims or made from sturdy cotton—can survive a machine wash cycle. But caution is key:

• Check the care label. Only machine wash your hat if the tag specifically states it’s safe to do so.
• Use protective gear. Place the hat inside a washing cage or mesh laundry bag to prevent it from getting crushed or losing its shape.
• Choose the right settings. Choose a gentle or delicate cycle, and always use cold or cool water to minimize stress on the fabric.
• Add the right detergent. Use a tablespoon of mild laundry detergent. Avoid dishwasher detergents—they’re too harsh and can damage the material.
• Skip the hot water. High temperatures can distort the hat’s shape and cause colors to fade.

After washing, reshape the hat and let it air dry using the same method described above.

Alternative Dishwasher Route

Washing hats in the dishwasher is a debated method, but it can work for newer hats with plastic inserts. Here’s how:

• Place the hat on the top rack and use a hat cage to help it hold its shape.
• Use cool water and a mild detergent.
• Avoid dishwasher detergents, as they may contain bleach or harsh chemicals.
• Skip the drying cycle—remove the hat before it starts and let it air dry to prevent heat damage.

This isn’t the safest method, but it can be effective if you follow the proper precautions.

2. Spot Cleaning & Soaking

Not every hat needs a full soak or machine wash. If you’re dealing with light surface dirt or want to maintain your hat between deep cleans, spot cleaning is a great option.

1. Dampen a damp cloth or soft brush.
2. Use mild detergent mixed with cool water.
3. Rub the stained area or affected area gently.
4. Rinse with a damp cloth to remove excess soap.
5. Let the hat air dry.

This is especially helpful for vintage hats, which may have cardboard brims or sensitive materials. Always test cleaning solutions on an inconspicuous area of the hat or a hidden part of the hat first to prevent damage.

Cleaning Specific Types of Hats

• Trucker Hat: Usually made with mesh backs and foam fronts, these are best cleaned by hand washing them in cold water and a mild detergent.
• Wool Baseball Caps: These need extra care. Stick to hand washing with cool water, a mild detergent, and a gentle scrubbing technique. Let them air dry to retain their shape.
• Bucket Hats: Soft and flexible, they handle hand washing well. Use a soft brush and let them air dry on a hat rack or towel.
• Vintage Baseball Cap: Handle with care due to potential cardboard inserts. Use the hand-washing method only.

Each hat needs a different way to be cleaned, so check what it’s made of before washing. With the right care, your hats will stay clean and last a long time.

3. Drying Your Hat

Properly drying your hat is just as important as washing it. The wrong method can lead to shrinking, fading, or a loss of shape. To keep your hat looking its best, follow these tips:

• Never use a dryer—heat can shrink or deform your hat, especially if it has a cardboard brim.
• Avoid drying in direct sunlight, which can cause fading or warping.
• Place a balled-up towel or clean cloth inside the hat to help it maintain its shape.
• Let the hat air dry in a cool, dry place with good airflow.
• Check on it occasionally and reshape it if needed while it dries.

By taking the time to air dry your hat properly, you’ll help it retain its shape, color, and fit for longer. A little extra care goes a long way in keeping your favorite hat looking fresh and ready to wear.

Additional Tips for Caring for Your Favorite Hats

To keep your hats looking good and lasting longer, follow these easy care tips for cleaning and storing them:

• Avoid hot water at all costs unless the label specifies it’s safe.
• Never dry hats in a dryer or with major appliances that emit heat.
• Keep hats in pristine condition with regular maintenance.
• When in doubt, go with the safest method: hand washing.
• Be cautious if the hat has sentimental or collector’s value; consult professionals if needed.
• Keep hats away from high heat to prevent skin irritation or structural damage.
• Never use oxygen bleach or strong chemicals unless approved for your hat’s material.
• If your hat exceeds a certain dollar threshold in value, consider spot cleaning only.
• Use cardboard inserts during drying to preserve the shape of hats that need structure.
