Can You Put a Cap in the Washing Machine? The Complete Guide
Placing a cap—especially a baseball cap—into the washing machine might sound like the quickest way to clean it. But is it safe for the cap? And will your cap come out looking as good as before, or end up misshapen and ruined? Let’s break down everything you need to know about washing caps in the machine so you can keep your headwear looking sharp and feeling fresh.
The Straight Answer: Is Washing a Cap in the Machine Safe?
The simple answer: it depends.
Some modern caps can handle a gentle cycle in the washing machine, while others can be damaged, stretched, or lose their shape entirely. The key factors are the cap’s material, construction, age, and whether you follow a few important precautions. For the best results, you’ll want to assess your cap and choose cleaning methods wisely.
Understanding the Parts and Materials
Before you toss your cap into the washer, it’s essential to know what it’s made of. Different caps handle water, agitation, and detergent in very different ways.
Common Cap Elements
- Brim (bill): The stiff part at the front. Older caps often have cardboard brims, while newer ones use plastic.
- Crown: The part that fits around your head. Made from cotton, polyester, wool, or blends.
- Sweatband: The inner band designed to absorb moisture.
Cap Materials and Washing
- Cotton and polyester: Generally washable, but can shrink or fade if treated harshly.
- Wool: Needs gentle cleaning; machine washing can shrink or distort it.
- Cardboard brim: Not washable; will warp or disintegrate when wet.
- Plastic brim: Can usually withstand careful washing.
When You Can (and Can’t) Machine Wash a Cap
Machine-Wash Friendly Caps
Your cap may be suitable for the washing machine if:
- It’s made after the 1980s (modern caps usually have plastic brims).
- The care label specifically allows machine washing.
- It’s not a collector’s item, signed memorabilia, or made from delicate/specialty fabrics.
- The shape is sturdy and the seams are intact.
Never Machine Wash These Caps
Avoid machine washing if:
- The brim feels like cardboard when you tap or bend it.
- It’s made of wool, suede, or leather.
- The cap is a vintage, collectible, or sentimental item.
- There are embellishments, glued patches, or handmade features.
When in doubt, hand washing is always safer.
Step-by-Step: How to Wash a Cap in the Washing Machine
If you’ve determined your cap is machine-washable, here’s how to do it right:
1. Check the Label
- Read any care instructions. If it says “hand wash only” or “spot clean,” skip the machine!
2. Pre-Treat Stains
- Use a gentle stain remover or mild detergent.
- Apply directly to sweatbands or stains with a soft toothbrush.
3. Prep the Cap
- Place the cap in a protective mesh laundry bag or a specially designed cap cage.
- This helps the cap keep its shape and prevents snagging.
4. Wash Gently
- Wash with like colors and lightweight items (think t-shirts, not jeans or towels).
- Use cold water—hot water can shrink fabrics and loosen glue.
- Select the gentle or delicate cycle.
5. Detergent
- Use a small amount of mild detergent.
- Avoid harsh chemicals or bleach.
6. Skip the Spin!
- Too much spinning can twist or crush the cap. If possible, skip the spin cycle or remove the cap before this phase.
7. Air Dry Only
- Absolutely do not use the dryer; heat can warp the cap.
- Instead, reshape the cap and let it air dry over a rounded object (like a small bowl, balled-up towel, or a hat stand).
- Never hang it by the brim, as this can deform the shape.
Benefits of Machine Washing Caps
- Convenience: Hands-free cleaning—just set the cycle and let the washer do the work.
- Effectiveness: Great for removing sweat, dirt, and odor, especially from polyester or cotton.
- Time-saving: Cleans thoroughly while you handle other chores.
Challenges & Risks of Machine Washing Caps
- Shape distortion: Brims and crowns can lose their form, making the cap look lopsided or sloppy.
- Color fading: Harsh cycles and detergents can dull vibrant colors.
- Stitch weakening: Vigorous agitation and spinning can stress or unravel seams.
- Water damage: Cardboard brims and certain fabrics can break down.
Practical Tips: Keep Your Cap Safe in the Machine
- Always use a mesh bag or cap shaper: These keep the cap from being pummeled and help it retain its form.
- Don’t overload the washer: Crowded loads mean more friction and possible damage.
- Stick to cold water: Hot water increases the risk of shrinking and fading.
- Dry with care: Stuff the cap with a towel or use a hat form to help it maintain shape as it dries.
- Double-check the fabric: If you’re not certain, consider hand washing just to be safe.
Alternatives to Machine Washing
If you’re hesitant about machine washing, or your cap is delicate or vintage, consider these gentler options:
- Hand washing: Use a sink or basin with lukewarm water and a mild detergent. Gently scrub, then rinse well.
- Spot cleaning: Dampen a cloth with soapy water and target only the stained areas.
- Cap cleaning kits: Some stores sell products specifically made to clean and reshape hats.
Hand washing, while less convenient, often extends the life of your favorite hats.
Common Mistakes to Avoid
- Using bleach or strong detergents.
- Washing with heavy or abrasive laundry (jeans, jackets, etc.).
- Putting the cap in the dryer.
- Ignoring the care label.
- Skipping the step of reshaping the cap while it dries.
What About Special Cap Types?
Wool Caps
Wash gently by hand in cool water. Machine washing can cause shrinkage or fuzziness.
Suede or Leather Caps
Do not wash with water. Use specialty cleaners designed for leather or suede.
Trucker Hats (Mesh Caps)
These often have plastic brims and mesh bodies, so gentle machine washing is sometimes possible. Use a laundry bag for added protection.
Collector or Signed Caps
Never machine wash! Spot clean with a damp cloth and keep them out of sunlight and excess moisture.
When to Replace Your Cap Instead
Despite all attempts at cleaning, some caps are better off replaced if:
- The sweat stains are permanent.
- The brim is warped or cracked.
- The stitching is coming undone.
- The color has faded beyond recognition.
Hanging onto an old favorite is tempting, but sometimes a fresh cap is the best option.
Final Thoughts
In summary, whether you can put a cap in the washing machine really depends on its construction, material, and age. Newer caps with plastic brims and sturdy stitching can often handle a gentle machine wash—but only with the right precautions. For delicate, vintage, or specialty caps, hand washing or spot cleaning will protect your headwear investment.
Always remember: when in doubt, treat your cap gently. A little extra care goes a long way toward keeping your favorite hats clean, fresh, and perfectly shaped.
Frequently Asked Questions (FAQs)
Can all caps be washed in the washing machine?
No, not all caps can be safely machine washed. Caps with cardboard brims, wool or leather materials, or special decorations should be washed by hand or spot cleaned instead.
How do I know if my cap has a cardboard or plastic brim?
Gently tap or bend the brim. Plastic brims feel flexible but don’t make a paper-like sound, while cardboard brims feel stiff and sometimes crunch or creak when bent.
Is it safe to dry a cap in the dryer after machine washing?
No, tumble drying can warp or shrink the cap. Always air dry your cap, placing it on a rounded object to help keep its shape.
What if the cap label says “hand wash only”?
Always follow the manufacturer’s instructions. “Hand wash only” means the cap shouldn’t go in the washing machine, as the risk of damage is high.
How often should I wash my cap?
Wash your cap whenever it shows visible dirt, sweat stains, or odor. Regular spot cleaning can help reduce the need for full washes and extend your cap’s lifespan.
With these tips and guidelines, you can enjoy cleaner, fresher caps—and keep your favorites looking their best, wash after wash!
